A linkage map for the B-genome of Arachis (Fabaceae) and its synteny to the A-genome

<p>Abstract</p> <p>Background</p> <p><it>Arachis hypogaea </it>(peanut) is an important crop worldwide, being mostly used for edible oil production, direct consumption and animal feed. Cultivated peanut is an allotetraploid species with two different genome components, A and B. Genetic linkage maps can greatly assist molecular breeding and genomic studies. However, the development of linkage maps for <it>A. hypogaea </it>is difficult because it has very low levels of polymorphism. This can be overcome by the utilization of wild species of <it>Arachis</it>, which present the A- and B-genomes in the diploid state, and show high levels of genetic variability.</p> <p>Results</p> <p>In this work, we constructed a B-genome linkage map, which will complement the previously published map for the A-genome of <it>Arachis</it>, and produced an entire framework for the tetraploid genome. This map is based on an F₂population of 93 individuals obtained from the cross between the diploid <it>A. ipaënsis </it>(K30076) and the closely related <it>A. magna </it>(K30097), the former species being the most probable B genome donor to cultivated peanut. In spite of being classified as different species, the parents showed high crossability and relatively low polymorphism (22.3%), compared to other interspecific crosses. The map has 10 linkage groups, with 149 loci spanning a total map distance of 1,294 cM. The microsatellite markers utilized, developed for other <it>Arachis </it>species, showed high transferability (81.7%). Segregation distortion was 21.5%. This B-genome map was compared to the A-genome map using 51 common markers, revealing a high degree of synteny between both genomes.</p> <p>Conclusion</p> <p>The development of genetic maps for <it>Arachis </it>diploid wild species with A- and B-genomes effectively provides a genetic map for the tetraploid cultivated peanut in two separate diploid components and is a significant advance towards the construction of a transferable reference map for <it>Arachis</it>. Additionally, we were able to identify affinities of some <it>Arachis </it>linkage groups with <it>Medicago truncatula</it>, which will allow the transfer of information from the nearly-complete genome sequences of this model legume to the peanut crop.</p

Identification of candidate genome regions controlling disease resistance in Arachis

<p>Abstract</p> <p>Background</p> <p>Worldwide, diseases are important reducers of peanut (<it>Arachis hypogaea</it>) yield. Sources of resistance against many diseases are available in cultivated peanut genotypes, although often not in farmer preferred varieties. Wild species generally harbor greater levels of resistance and even apparent immunity, although the linkage of agronomically un-adapted wild alleles with wild disease resistance genes is inevitable. Marker-assisted selection has the potential to facilitate the combination of both cultivated and wild resistance loci with agronomically adapted alleles. However, in peanut there is an almost complete lack of knowledge of the regions of the <it>Arachis </it>genome that control disease resistance.</p> <p>Results</p> <p>In this work we identified candidate genome regions that control disease resistance. For this we placed candidate disease resistance genes and QTLs against late leaf spot disease on the genetic map of the A-genome of <it>Arachis</it>, which is based on microsatellite markers and legume anchor markers. These marker types are transferable within the genus <it>Arachis </it>and to other legumes respectively, enabling this map to be aligned to other <it>Arachis </it>maps and to maps of other legume crops including those with sequenced genomes. In total, 34 sequence-confirmed candidate disease resistance genes and five QTLs were mapped.</p> <p>Conclusion</p> <p>Candidate genes and QTLs were distributed on all linkage groups except for the smallest, but the distribution was not even. Groupings of candidate genes and QTLs for late leaf spot resistance were apparent on the upper region of linkage group 4 and the lower region of linkage group 2, indicating that these regions are likely to control disease resistance.</p

Ser e estar ansioso: a busca de plantas medicinais e fitoterápicos no tratamento do transtorno de ansiedade generalizado e a influência das políticas públicas

A ansiedade pode ser entendida sob diferentes óticas, como um sentimento desagradável relacionado ao medo e a apreensão que gera desconforto, ou como uma resposta fisiológica do organismo desencadeada por eventos. Para o tratamento dos transtornos relacionados a ansiedade, são utilizados medicamentos e associados a eles estão a prática de atividade física e a mudança dietética. No entanto, muitos desses medicamentos apresentam efeitos adversos indesejados, o que leva o paciente a buscar por novas alternativas. Nesse cenário, surge o uso dos fitoterápicos, os quais são obtidos, exclusivamente, de matérias-primas vegetais. A presente revisão sistemática com metanalise estatística objetivará verificar se o uso da fitoterapia está diretamente ligado ao alívio dos sintomas da ansiedade em pesquisas realizadas entre 2015 a 2021 em uma perspectiva cienciométrica. Para a realização dessa revisão sistemática com análise estatística, as seguintes variáveis respostas serão coletadas: (i) Ano de publicação dos artigos encontrados dentro do objetivo deste trabalho; (ii) Periódico em que o artigo foi publicado; (iii) Primeiro autor do artigo encontrado; (iv) Resultados estatisticamente positivos para a ansiedade e fitoterápicos/plantas medicinais; (v) Diferentes quantidades de uso em ansiolíticos e fitoterápicos utilizadas nas metodologias das pesquisas; (vi) Resultados sobre utilização de plantas medicinais (vii) Estado brasileiro no qual a pesquisa foi desenvolvida. Com estas variáveis, será possível mensurar descrever características sobre o transtorno de ansiedade, seu impacto sobre as pessoas, e a utilização de plantas medicinais/fitoterápicos em comparação com o uso de outras drogas

Investigation of an outbreak of disease compatible with scurvy in a male penitentiary in the state of Ceará, Brazil, 2019-2020: a case-control study

ABSTRACT Objective: to identify the occurrence of an outbreak compatible with scurvy and exposure factors associated with typical signs/symptoms of hypovitaminosis that occurred in a male penitentiary in Ceará, Brazil between 2019-2020. Methods: this was a population-based case-control study; we used clinical records and interviews with compatible cases - based on sign/symptom onset during the study period - and with controls; we carried out multivariate analysis. Results: out of 62 cases, mean age was 40.6 years (SD = 10.8); main signs/symptoms were edema and pain in the lower limbs (100.0%), difficulty in walking (91.9%), hematoma/ecchymosis in the lower limbs (90.3%) and fever (88.7%); we identified being over 40 years old as an associated factor (aOR = 1.10; 95%CI 1.05;1.17; p-value = 0.001); and as protective factors: working (aOR = 0.11; 95%CI 0.03;0.36; p-value < 0.001) and taking part in classes (aOR = 0.21; 95%CI 0.08;0.59; p-value = 0.003) in the prison. Conclusion: we considered the penitentiary outbreak to be compatible with scurvy due to characteristic signs/symptoms, associated with the identified factors; we recommended regular provision of a diet rich in vitamin C to all male inmates and clinical follow-up of cases

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
