What is brassinolides?

Brassinolides are a group of plant hormones that regulate several physiological processes in plants, including cell elongation, growth, differentiation, and stress response. They were discovered early in the 1970s and are part of the steroid hormone family.

Brassinolides are produced in the cytoplasm and move through the plant's vascular system to initiate signaling and regulate cellular functions. They bind to cell surface receptors called BRI1 (Brassionosteroid Insensitive 1) to activate intracellular signaling cascades that activate various genes involved in plant growth and development.

Brassinolides have been found to enhance plant growth, increase seed germination and yield, improve stress tolerance, and stimulate root growth. They are also involved in regulating flowering time, leaf senescence, and fruit ripening.

Currently, brassinolides find applications in agriculture as a commercial plant growth regulator to optimize crop yields and improve the overall quality of agricultural production. They commonly come in a sprayable formulation and can be used for a variety of crops including rice, wheat, corn, cotton, and vegetables.
