Interests: Mechanisms of genetic regulation of the brassinosteroid biosynthesis and signaling in plants, particularly in barley. This area of interest encompasses characterization of physiological and metabolic reaction of semi-dwarf barley mutants defective in BR metabolism to environmental stresses, particularly drought and heat stress.
Special Issue Information
Dear Colleagues,
Brassinosteroids (BRs) are a class of steroid phytohormones which regulate key metabolic, cellular, and physiological processes in plants. Intensive studies conducted over the last three decades, mostly in the model species Arabidopsis thaliana, have led to the identification of numerous genes regulating BR biosynthesis and signaling. This has enabled great progress in allowing these processes to be described. However, these aspects are far less understood in other plant species, including crops. Moreover, many recent reports indicate that regulatory functions of BRs and their impact on plant biology is mediated through a complicated network of interactions involving metabolic pathways of other phytohormones. Although the emerging view of inter-hormonal crosstalk is quite complicated, understanding this is crucial for elucidating the mechanisms and responses of plant development and adaptation to constantly changing environmental conditions. Interestingly, an accumulating body of evidence indicates that genetic regulation of the phytohormonal metabolism and crosstalk involves a group of microRNAs, which has opened a new, fascinating direction in this area of research. Understanding of these issues is very important, taking into account the key role of BRs in the regulation of plant metabolism and stress response, particularly in the face of global climate change.
Therefore, the scope of this Special Issue encompasses various aspects of brassinosteroid biosynthesis, signaling, and metabolism in relation to their physiological functions and interconnection with other phytohormones. The Special issue aims to address these aspects in model and crop species. We welcome original research articles from the areas of plant genetics, biochemistry, and physiology, as well as reviews that fit into the above-described scope.
