Title: Brassinosteroids in Transit: The Role of Short-Distance Transport in Maintaining Brassinosteroid Homeostasis
Abstract:
Brassinosteroids are steroidal phytohormones essential for plant growth, development, and adaptation to environmental stresses. Acting in a dose-dependent manner, they do not move over long distances within plants, making the maintenance of brassinosteroid homeostasis crucial for their function. In roots, bioactive brassinosteroid synthesis depends on cell-to-cell movement of hormone precursors, while brassinosteroid perception in the apoplast requires their export from the cell. However, the mechanisms governing short-distance brassinosteroid transport remain unknown, and its role in regulating endogenous brassinosteroid levels is still unexplored.
In this presentation, I will provide evidence for the symplastic movement of brassinosteroids and their active export to the apoplast, where they initiate signalling. Our work reveals a previously unrecognized mode of steroid transport in eukaryotes and highlights an additional layer of brassinosteroid homeostasis regulation in plants, which is vital for brassinosteroid function.
