Why are brassinosteroids important in plant biology? Brassinosteroids regulate a wide range of physiological processes including plant growth, development and immunity. How do brassinosteroids affect plant growth? · brassinolide steroids, also known as brassinosteroids, are naturally occurring plant hormones that regulate a plant’s growth, development and immunity. Brassinosteroids (brs) are a class of polyhydroxylated steroidal phytohormones in plants with similar structures to animals’ steroid hormones. Are brassinolide steroids a natural fertilizer? However, br signaling also plays a role in various developmental processes, including reproductive and vascular development. Tae-wuk et al. , 2012). What are brassinolide steroids? · this review aims to provide an in-depth examination of the critical functions of brassinolide in plant growth and metabolism. · after brassinolide (br) enters the plant , it not only enhances photosynthesis and promotes growth and development, but also has a special protective effect on the plant cell membrane system to resist reverse environmental damage. Additionally, the complex molecular mechanisms of brs biosynthesis, signal transduction, and its interactions with other plant hormones were identified. The hormone is naturally produced, as needed, to help plants grow, create pollen, set flowers, fruits and seeds, and resist diseases or pests. In arabidopsis, the process begins with the bri1 receptor (brassinosteroid insensitive 1 receptor). They are involved in several aspects of plant development and growth including cell division and expansion, shoot induction, differentiation of vascular tissue, and stomatal development (cheon et al. , 2010; · br action in plants the essential role of br signaling in plant growth is evident to the naked eye when observing null mutants for br signaling and biosynthesis. This receptor is a type of protein called a leucine-rich receptor kinase and allows brassinolide to attach to it from outside the cell.
