Brassinosteroids (BRs) are steroid phytohormones which regulate various developmental and physiological processes throughout plant life cycle, from seed development germination, up to modulation of reproduction senescence. Importantly, mutants defective in the BR biosynthesis or response show degree height reduction (dwarfism semi-dwarfism). This agronomic trait is particular importance considering that contrast tall cereal varieties, semi-dwarf plants more tolerant lodging occurs during unfavorable weather conditions constitutes a serious threat yield. Moreover, it was shown deficiency insensitivity lead erect stature what enables increase planting density The valuable combinations these traits make BR-related exceptional alternatives breeding programs. Noteworthy, BRs play noticeable role regulation grain/kernel shape size. Therefore, crucial may be manipulated specifically BR-dependent manner. have been successfully introduced into programs past, new developed through application gene editing approach recently reported as promising for novel, high-yielding cultivars. review presents comprehensive description genetic manipulations genes aimed at improvements major crops - rice, wheat, maize, barley. These achieved panicle- grain-specific promoters, overexpression gain-of-function approaches, silencing, targeted editing.
