Benefits of brassinosteroid crosstalk.
Brassinosteroids (BRs) are a group of phytohormones that regulate various biological processes in plants. Interactions and crosstalk between BRs and other plant hormones control a broad spectrum of physiological and developmental processes. In this review, we examine recent findings which indicate that BR signaling components mainly interact with the signaling elements of other hormones at the transcriptional level. Our major challenge is to understand how BR signaling independently, or in conjunction with other hormones, controls different BR-regulated activities. The application of a range of biotechnological strategies based on the modulation of BR content and its interplay with other plant growth regulators (PGRs) could provide a unique tool for the genetic improvement of crop productivity in a sustainable manner.
