Volatile Profile of Wall Rocket Baby-Leaves (Diplotaxis erucoides) Grown under Greenhouse: Main Compounds and Genotype Diversity
[EN] Wall rocket is a leafy vegetable with pungent flavor related to the presence of isothiocyanates (ITCs). Despite interest in it as a crop of high organoleptic quality, the variability of the volatile profile in the species remains unknown. Twenty-four populations grown under a greenhouse were evaluated. A considerable diversity for the total levels of volatiles was found, providing information of the aroma intensity among accessions. ITCs represented the main fraction. Allyl ITC was the main compound, and levels showed up to 6-fold difference among populations. The esters fraction was mainly represented bycis-3-hexenyl isovalerate andcis-3-hexenyl butyrate, with 20-fold differences among populations. Additionally, the content in sinigrin was evaluated as main GSL in wall rocket. Differences reached up to 13-fold. These results suggest that some populations can be used to develop highly pungent varieties, whereas some others can be selected for mild-pungent varieties, as it is the case of DER045 with low levels of ITCs and high in esters. The presence of several ITCs in the profile also suggested the presence of other novel GSLs. Overall, the work increases the knowledge in the variability of wall rocket for the volatile profile and sinigrin accumulation, a starting point for future breeding programs.C.G. thanks the Ministerio de Educacion, Cultura y Deporte of Spain (MECD) for the financial support by means of a predoctoral FPU grant (FPU14-06798).Guijarro-Real, C.; Rodríguez Burruezo, A.; Fita, A.

Prospección, recuperación, selección y pre-domesticación de plantas autóctonas con alto potencial funcional
Tesis por compendio[ES] En las sociedades modernas ha aumentado la demanda de alimentos funcionales, así como la alimentación como una experiencia gastronómica. Surge así una oportunidad de revalorizar el uso de plantas silvestres comestibles mediante su domesticación y adaptación a cultivo. Algunas de estas especies, además de incorporar sabores distintos, son percibidas como beneficiosas para la salud, factor que a nivel científico puede corresponder con la acumulación de compuestos bioactivos.
La presente Tesis es un trabajo de evaluación y pre-domesticación de dos especies de amplia distribución en nuestra región, destacadas por su alto potencial funcional y calidad organoléptica. El objetivo es, por un lado, aumentar el conocimiento en estos componentes de la calidad; y por otra parte, establecer una base para los programas de domesticación y adaptación a cultivo.
La primera parte de esta Tesis se centra en el potencial de la berraza. Hasta la fecha se ha descrito su alto potencial en términos de contenido en fenoles totales y capacidad reductora de radicales libres. Nuestros resultados ampliando el número de muestras no sólo confirman dicho potencial, sino que establecen además una clara correlación entre ambos caracteres. Se sugiere así que la capacidad reductora de la berraza está principalmente definida por la acumulación de compuestos fenólicos, especialmente derivados de la quercetina. Por otro lado, el perfil volátil revela una prevalencia de compuestos terpenoides y fenilpropanoides. Este perfil es único en comparación con otras especies cultivadas; se identifican, sin embargo, ciertas similitudes que podrían explicar la relación de sabor entre ellas. Pese a su interés funcional y aromático, el cultivo convencional resulta poco prometedor. Queda no obstante la vía abierta a nuevos trabajos de adaptación a cultivo hidropónico como alternativa prometedora.
La segunda parte de la Tesis está orientada al estudio de la rabaniza. Debido a la latencia secundaria de su semilla, se hace necesario en primer lugar establecer un tratamiento efectivo que permita obtener una germinación elevada y uniforme. Nuestros resultados sugieren un uso combinado de hipoclorito de sodio y ácido giberélico, tratamiento adecuado en los programas de mejora y que puede ser además adaptado para su uso comercial a gran escala.
Los resultados de calidad funcional destacan especialmente la acumulación de ácido ascórbico, de alto poder antioxidante. En su perfil de glucosinolatos destaca la sinigrina, de potencial funcional y responsable en gran medida de su aroma; los resultados sugieren, no obstante, la síntesis de otros glucosinolatos. Es, por el contrario, acumuladora de nitratos como antinutrientes, factor que será determinante en las prácticas aplicadas para su futuro cultivo.
Se han caracterizado además los materiales disponibles para identificar rasgos de interés a nivel morfoagronómico. La moderada variabilidad morfológica tiene claras implicaciones para los programas de mejora, limitando el número de cultivares a desarrollar. Por otra parte, el test hedónico sugiere que se pueden desarrollar distintos productos comerciales, como germinados y brotes tiernos, destinados a distintos nichos de mercado.
Finalmente, se han evaluado dos sistemas modelo de cultivo, campo e invernadero, y el comportamiento en diversos ciclos. La producción en campo aumenta la calidad visual y funcional, con mayor contenido en vitamina C y fenoles y menor acumulación de nitratos. Sugerimos pues la producción de rabaniza en campo. No obstante, los meses más fríos pueden afectar negativamente la calidad, lo que supone una vía a nuevos estudios.
En definitiva, los trabajos de esta Tesis aumentan, por un lado, el conocimiento morfroagronómico, nutracéutico y volátil de las plantas silvestres utilizadas. Suponen además una base para el establecimiento de estas especies como nuevos cultivos en las regiones mediterráneas, identifican[CA] En les societats modernes ha augmentat la demanda d'aliments funcionals i s'ha promogut a més l'alimentació com una experiència gastronòmica. Sorgeix així una oportunitat de revaloritzar l'ús de plantes silvestres comestibles, mitjançant la seua domesticació i adaptació a cultiu. Algunes d'aquestes espècies, a més d'incorporar sabors diferents, són percebudes com a beneficioses per a la salut, factor que a nivell científic pot correspondre amb l'acumulació de compostos bioactius.
La present Tesi es un treball d'avaluació i pre-domesticació de dues espècies d'àmplia distribució a la nostra regió, destacades per un alt potencial funcional i qualitat organolèptica. L'objectiu és, d'una banda, augmentar el coneixement d'aquests dos components de la qualitat; i d'altra banda, establir una base per als programes de domesticació i adaptació a cultiu.
La primera part d'aquesta Tesi se centra en el potencial del creixen de sèquia. Fins hui s'ha descrit el seu potencial en termes de contingut en fenols totals i capacitat reductora de radicals lliures. Els nostres resultats ampliant el nombre de mostres no solament confirmen aquest potencial, sinó que estableixen a més una clara correlació entre els dos caràcters. Se suggereix així que la capacitat reductora del creixen està principalment definida per l'acumulació de compostos fenòlics, especialment derivats de la quercetina. D'altra banda, el perfil volàtil revela una prevalença de compostos terpenoids i fenilpropanoids. Aquest perfil és únic en comparació amb altres espècies cultivades; no obstant això, s'identifiquen certes similituds que podrien explicar la relació entre aquestes espècies. Malgrat el seu interés funcional i aromàtic, el cultiu convencional és poc prometedor. No obstant això, queda oberta la via a nous treballs d'adaptació a cultiu hidropònic com a alternativa prometedora.
La segona part de la Tesi està orientada a l'estudi de la ravenissa. A causa de la latència secundària de la seua llavor, es fa necessari en primer lloc establir un tractament efectiu que permeta obtindre una germinació elevada i uniforme. Els resultats suggereixen un ús combinat d'hipoclorit de i àcid giberèlic. Aquest tractament és adequat en els programes de millora i pot ser a més adaptat per al seu ús comercial a gran escala.
Els resultats de qualitat funcional destaquen l'acumulació d'àcid ascòrbic, de gran poder antioxidant. En el seu perfil de glucosinolats destaca la sinigrina, de potencial funcional i responsable en gran manera de la seua aroma; els resultats suggereixen, a més, la síntesi d'uns altres glucosinolats. És, per contra, acumuladora de nitrats com a antinutrients, factor que serà determinant en les pràctiques que s'empren per al seu futur cultiu.
S'han caracteritzat a més els materials disponibles per a identificar caràcters d'interés morfoagronòmic. La moderada variabilitat morfològica té clares implicacions per als programes de millora, limitant el nombre de varietats comercials a desenvolupar. D'altra banda, el test hedònic suggereix que es poden desenvolupar diferents productes comercials com són germinats i brots tendres, destinats a diferents mercats.
Finalment, s'han avaluat dos sistemes de cultiu, camp i hivernacle, i el comportament en diversos cicles. La producció en camp augmenta la qualitat visual i funcional, amb un major contingut en vitamina C i compostos fenòlics i menor acumulació de nitrats. Suggerim doncs la producció de ravenissa sota camp. No obstant això, els mesos més freds poden afectar negativament la qualitat, el que suposa una via a nous estudis.
En definitiva, els treballs d'aquesta Tesi augmenten, d'una banda, el coneixement morfroagronòmic, nutricèutic i volàtil de les plantes silvestres utilitzades. Suposen a més una base per a l'establiment d'aquestes espècies com a nous cultius adaptats a les regions mediterrànies, identificant punts clau per a la seua adaptaci[EN] Modern societies have increased the demands on functional, as well as the consideration of feeding as a gastronomic experience. These key points encourage the revalorization of wild edible plants by means of the domestication and adaptation into crop systems. Some of these species, apart from providing new tastes, are also perceived as beneficial for health. These perceived benefits can scientifically correspond to the accumulation of bioactive compounds.
The current Thesis is aimed at the evaluation and pre-domestication of two wild species broadly found in our region, which highlight for their functional potential and organoleptic quality. The aim is, on one hand, to increase the knowledge on these components of quality; and, on the other hand, to establish a basis for the domestication and crop adaptation programs.
The first part of this Thesis is focused on analyzing the potential of water celery. Previous authors have described high antioxidant properties for this species in terms of content in total phenolics and free radical scavenging capacity. Our work with a larger quantity of materials confirms this potential and establishes a clear correlation between both traits. Thus, we suggest that the free radical scavenging capacity is mainly due to the accumulation of phenolics, mainly quercetin derived compounds. On the other hand, the volatile profile is rich in terpenoid compounds and phenylpropanoids. Such profile is unique compared to other cultivated species. However, there are some similarities that may explain the resemblances among them. Despite the functional and aromatic interest of water celery, its adaptation into conventional systems is not greatly promising. Nevertheless, we suggest that future works could consider the hydroponic system as a promising alternative.
The second part of this Thesis is focused on the study of wall rocket. Due to the secondary dormancy of their seeds, it is firstly needed the establishment of an adequate treatment for a high and uniform germination. Our results suggest the synergistic use of sodium hypochlorite together with gibberellic acid. This treatment can be successfully used in breeding programs, and also adapted for commercial application in a productive scale.
Results of the functional quality highlight the accumulation of ascorbic acid, with high antioxidant power. Sinigrin is the main glucosinolate determined. Sinigrin has high functional potential and is great responsible of the aroma in wall rocket. Moreover, results suggest that other glucosinolates are also present. On the other hand, wall rocket accumulates high levels of nitrates as antinutrients. This trait is a critical determinant for the cultivation practices to be used.
The available materials have been also characterized in order to identify morphoagronomic traits of interest. The moderate morphological variability has clear implications for breeding programs and the quantity of cultivars that can be obtained. On the other hand, the hedonic test suggests that several products could be commercially exploited, including microgreens and baby-leaves. The development of different commercial products can increase the market opportunities.
Finally, two model systems of cultivation, field and greenhouse, and also the behavior of plants under different growing cycles, have been evaluated. The field production increases the visual and functional quality, with the enhancement of vitamin C and total phenolic and the reduction of nitrates. Thus, we suggest that commercial production should be performed under field conditions. Nevertheless, increasing the quality during the coldest months is still an area of study.
In summary, this Thesis increase the morphoagronomic, nutraceutical and volatile knowledge on the wild plants used. In addition, these works are a basis for the establishment of these species as new crops adapted to the Mediterranean regions, with the identification of key points for crop adaptation.Guijarro Real, C.

Notch Pathway Modulation on Bone Marrow-Derived Vascular Precursor Cells Regulates Their Angiogenic and Wound Healing Potential
Bone marrow (BM) derived vascular precursor cells (BM-PC, endothelial progenitors) are involved in normal and malignant angiogenesis, in ischemia and in wound healing. However, the mechanisms by which BM-PC stimulate the pre-existing endothelial cells at sites of vascular remodelling/recovery, and their contribution towards the formation of new blood vessels are still undisclosed. In the present report, we exploited the possibility that members of the Notch signalling pathway, expressed by BM-PC during endothelial differentiation, might regulate their pro-angiogenic or pro-wound healing properties. We demonstrate that Notch pathway modulates the adhesion of BM-PC to extracellular matrix (ECM) in vitro via regulation of integrin alpha3beta1; and that Notch pathway inhibition on BM-PC impairs their capacity to stimulate endothelial cell tube formation on matrigel and to promote endothelial monolayer recovery following wounding in vitro. Moreover, we show that activation of Notch pathway on BM-PC improved wound healing in vivo through angiogenesis induction. Conversely, inoculation of BM-PC pre-treated with a gamma secretase inhibitor (GSI) into wounded mice failed to induce angiogenesis at the wound site and did not promote wound healing, presumably due to a lower frequency of BM-PC at the wound area. Our data suggests that Notch pathway regulates BM-PC adhesion to ECM at sites of vascular repair and that it also regulates the capacity of BM-PC to stimulate angiogenesis and to promote wound healing. Drug targeting of the Notch pathway on BM-PC may thus represent a novel strategy to modulate neo-angiogenesis and vessel repair
Cellular polarity in aging: role of redox regulation and nutrition
Cellular polarity concerns the spatial asymmetric organization of cellular components and structures. Such organization is important not only for biological behavior at the individual cell level, but also for the 3D organization of tissues and organs in living organisms. Processes like cell migration and motility, asymmetric inheritance, and spatial organization of daughter cells in tissues are all dependent of cell polarity. Many of these processes are compromised during aging and cellular senescence. For example, permeability epithelium barriers are leakier during aging; elderly people have impaired vascular function and increased frequency of cancer, and asymmetrical inheritance is compromised in senescent cells, including stem cells. Here, we review the cellular regulation of polarity, as well as the signaling mechanisms and respective redox regulation of the pathways involved in defining cellular polarity. Emphasis will be put on the role of cytoskeleton and the AMP-activated protein kinase pathway. We also discuss how nutrients can affect polarity-dependent processes, both by direct exposure of the gastrointestinal epithelium to nutrients and by indirect effects elicited by the metabolism of nutrients, such as activation of antioxidant response and phase-II detoxification enzymes through the transcription factor nuclear factor (erythroid-derived 2)-like 2 (Nrf2). In summary, cellular polarity emerges as a key process whose redox deregulation is hypothesized to have a central role in aging and cellular senescence.PTDC/QUI/69466/2006PTDC/QUI-BIQ/104311/2008PTDC/BIA-PRO/101624/2008PEst-OE/QUI/UI0612/201
Co-creating social and sustainable innovation in makerspaces and fab labs. Lessons learnt from the SISCODE European project
“Making” and the Fourth Industrial Revolution have been extensively investigated in the last few years. Several pieces
of research have been carried out on the topic of fab lab networks and makers movements; in many cases, these
studies highlighted problems of their economic sustainability, stressing -however- their cultural-related role.
Nowadays, it is evident that Makerspaces and Fab Labs do not only produce physical goods, but they also develop
knowledge and relationships, which are expressed through physical productions and activities.
The European Union has been particularly interested in the study and development of innovative ecosystems, which
might serve as levers for sustainable growth, because of their focus on co-creation and the involvement of different
groups of stakeholders. SISCODE Horizon 2020 project was developed according to this European requirement.
Within the SISCODE project, a co-creation methodology for societal challenges was proposed and tested throughout
ten pilot projects carried out by Living Labs, Science Museums and Makerspaces, and Fab Labs.
In this paper, we are going to present the three pilot projects developed by three Makerspaces and Fab Labs
(Polifactory (Milan), Maker (Copenhagen), and Fab Lab Barcelona) and discuss main insights on co-creation practices
Potential of wall rocket (Diplotaxis erucoides) as a new crop: influence of the growing conditions on the visual quality of the final product
[EN] Wild edible plants can be used for developing new crops and diversifying food markets. Wall rocket (Diplotaxis erucoides) is an annual weed with potential as a new crop. The present study aims at evaluating the effects of different growing conditions in the visual quality of this potential new crop. We evaluated eleven accessions of wall rocket, together with commercial rocket accessions (Eruca sativa and D. tenuifolia). Experiments were simultaneously conducted under field and greenhouse systems, and performed during two seasons. Fifteen descriptors related to leaf size, colour and shape were evaluated. Analysis of variance detected significant differences in size and shape among the three species studied, revealing the distinctiveness of wall rocket from the other rocket crops. This distinctiveness may enhance its establishment as a new crop. Comparison between the wall rocket accessions was also performed. There was relatively low morphological diversity among them. By contrast, the growing conditions had a high effect on the visual quality, especially for colour related traits and intensity of lobation, and also in the flowering time. As a consequence, the heritability estimates were low to moderate. The principal component analysis (PCA) clustered accessions according to the growing conditions, thus reinforcing the importance of environment in the morphology of wall rocket. The most promising quality of the leaves was obtained under field conditions, where the bright green colour and intensity of lobation were enhanced. In particular, accession DER006-1 was identified as a good candidate for developing a new cultivar. These results establish a basis for the management of wall rocket as a new crop. At the same time, results regarding the low diversity registered for morphology in the accessions evaluated have important implications for future breeding programmes of wall rocket.C.

Morphological diversity and bioactive compounds in wall rocket (Diplotaxis erucoides (L.) DC.)
[EN] Wall rocket is a wild vegetable with interest to become a crop. However, the information regarding morphological variability in the species is scarce, despite the interest it has received for breeding programs. In addition, evaluating the phytochemical composition can also be useful for developing materials of a high quality. In this study, forty-four populations were evaluated for selected morphoagronomic traits and contents in ascorbic acid (AA), total phenolics (TP), and nitrates (NO3¿). Wall rocket plants had, on average, an intermediate growth habit and a good response to transplant. Moderate variability, mainly for size-related traits, was found, with low to moderate heritability estimates (H2 < 0.35). A Principal Component Analysis revealed that some materials may be selected for differenced traits. On the other hand, wall rocket materials had, on average, high contents in AA (53 mg 100 g¿1) and TP (116 mg CAE 100 g¿1) but also accumulated high levels of NO3¿ (891 mg 100 g¿1). Significant positive correlations were found for AA and TP, which could be exploited for increasing the antioxidant activity and properties of the final product. We provide new information on the variation of wall rocket for traits of morphological and phytochemical interest, which together with other traits, such as the profile of glucosinolates, can be useful for the selection of materials in future breeding programs.C.G. thanks the Ministerio de Educacion, Cultura y Deporte of Spain (MECD) for the financial support by means of a predoctoral FPU grant (FPU14-06798).

Consumers acceptance and volatile profile of wall rocket (Diplotaxis erucoides)
[EN] Wall rocket (Diplotaxis erucoides) is a wild edible herb traditionally consumed in the Mediterranean regions with a characteristic, pungent flavour. However, little is known about its acceptance as a potential new crop. In the present study, an hedonic test with 98 volunteers was performed in order to evaluate the potential of wall rocket as a new crop. Three products were tested corresponding to microgreens, seedlings and baby-leaves. The volatile constituents were also studied due to their probable influence on acceptance, and compared to Dijon's mustard and wasabi. The degree of acceptance was mainly related to taste and pungency. Microgreens were well accepted, whereas seedlings and baby-leaves were mainly appreciated by individuals that enjoy pungent tastes. The purchase intent was also highly related to the acceptance of taste and pungency. The volatiles profile revealed that wall rocket was rich in allyl isothiocyanate, like mustard and wasabi. This compound may be greatly responsible of the relationship between the acceptance of mustard, wasabi and wall rocket. Microgreens displayed the highest levels of isothiocyanates, although the quantity of product tested by panellists did not probably allow the appreciation of such compounds. In baby-leaves, a significant decrease in isothiocyanates GC area and relative abundances was observed. These results suggest that wall rocket microgreens would be accepted by a significant proportion of the general public since pungency is lowly perceived in the product, despite its high levels of isothiocyanates. By contrast, baby-leaves may become a crop for a cohort of consumers that enjoy pungent flavours.C.

Influence of the Growing Conditions in the Content of Vitamin C in Diplotaxis erucoides
Diplotaxis erucoides is an edible plant with potential for marketing. Here, we analysed the influence of the growing conditions in this species, D. tenuifolia and Eruca sativa, and studied the relation among the ascorbic (AA) and dehydroascorbic (DHA) acid forms. Plants were grown in the late winter-spring season under two conditions, greenhouse and field. The contents in AA, DHA and vitamin C (VC) were analysed by HPLC. The content of VC and AA were, in general, remarkable higher in the plants grown in the field. On the other hand, the mean percentage of DHA was less than 11%, being in this case higher for plants grown in the greenhouse. Thus, growing this potential crop in the field seems a better option in order to increase the content in VC, being AA the main form present at the moment of gathering
