In this way, what are Brassinosteroids and how do they act in plants?

Brassinosteroids (BRs) are plant steroid hormones that regulate cell proliferation and other developmental processes (Kim and Wang, 2010). They act through a complex signaling pathway that leads to activation of two transcription factors, BZR1 and BES1, which in turn modify the expression of over 1000 genes.

Also, what do gibberellins do? Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence.

In this way, how do Brassinosteroids affect growth and development of plants?

The plant steroid hormone brassinosteroids (BRs) play important roles in plant growth and development, regulating diverse processes such as cell elongation, cell division, photomorphogenesis, xylem differentiation, and reproduction as well as both abiotic and biotic stress responses.

What does auxin do in plants?

They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation. Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant.
