Description

Brassinolide is a naturally occurring plant steroid hormone that plays a crucial role in regulating plant growth and development. It is considered the most potent member of the brassinosteroid family. Brassinolide has been shown to promote cell elongation, division, and differentiation, as well as enhance photosynthesis, stress tolerance, and yield. Its synthesis involves a complex pathway with multiple enzymatic steps. Researchers study brassinolide due to its potential for improving crop yields, enhancing stress resistance in plants, and contributing to a better understanding of plant growth and development. Its effects on plant physiology have led to the development of synthetic brassinosteroid analogs that are being investigated as potential agricultural bioregulators.'
