    The paper presents the data of gaseous and alkali elements in above-ground biomass of energy crops. The investigations objects were Phalaris arundinacea L., Populus nigra, Artemisia vulgaris, Sylphium perfoliatum, Sida hermaphrodita, Dactylis glomerata, Salix viminalis, Medicago sativia L. The aim of the research: to evaluate the amount of chemical elements in energy crops. Evaluating the energy crops it can be seen, that the most alkaline metals are contained in Sida hermaphrodita, and the least in Sylphium perfoliatum L

    New fluorescent auxin probes visualise tissue‐specific and subcellular distributions of auxin in Arabidopsis

    In a world that will rely increasingly on efficient plant growth for sufficient food, it is important to learn about natural mechanisms of phytohormone action. In this work, the introduction of a fluorophore to an auxin molecule represents a sensitive and non‐invasive method to directly visualise auxin localisation with high spatiotemporal resolution. The state‐of‐the‐art multidisciplinary approaches of genetic and chemical biology analysis together with live cell imaging, liquid chromatography–mass spectrometry (LC‐MS) and surface plasmon resonance (SPR) methods were employed for the characterisation of auxin‐related biological activity, distribution and stability of the presented compounds in Arabidopsis thaliana. Despite partial metabolisation in vivo, these fluorescent auxins display an uneven and dynamic distribution leading to the formation of fluorescence maxima in tissues known to concentrate natural auxin, such as the concave side of the apical hook. Importantly, their distribution is altered in response to different exogenous stimuli in both roots and shoots. Moreover, we characterised the subcellular localisation of the fluorescent auxin analogues as being present in the endoplasmic reticulum and endosomes. Our work provides powerful tools to visualise auxin distribution within different plant tissues at cellular or subcellular levels and in response to internal and environmental stimuli during plant development

    Contains fulltext : 216444.pdf (publisher's version ) (Open Access)Rapid population growth together with improving living standards is causing bigger and more rapid consumption of resources in industrial, household and personal consumption areas. Unsustainable consumption patterns are negatively affecting our surroundings. In order to promote sustainable consumption it is important to engage consumers in active and mutual dialogue. This study introduces the construct of consumer engagement into the context of sustainable consumption and aims at revealing the factors influencing consumer engagement in sustainable consumption. Two groups of factors, internal and external, each comprising three determinants (environmental attitude, perceived responsibility and perceived behavioral efficiency; and conditions for sustainable consumption, social environment and promotion of sustainable consumption) were identified as having direct positive impact on consumer engagement in sustainable consumption, which in turn had a positive impact on green product buying. The results revealed an important mediating role of the consumer engagement construct, suggesting that application of the engagement construct in the context of sustainable consumption would allow a deepening understanding of actual consumer behavior related with different contexts of sustainable consumption.12 februari 202019 p
