Brassinolide is a potent growth-promoting hormone that is believed to be a key element in the plant's response to light. Such responses, which include adjusting plant growth to reach light or strengthening stems to support leaves, are central to plant survival.

Brassinosteroids are essential for normal plant growth, development, and reproduction; mutants that cannot make brassinolide are dwarfs and are generally sterile. In contrast to what is known about steroids in animals, very little is known about the mechanisms of how brassinosteroids work at a cellular level in plants.

Brassinolide is a naturally occurring plant steroid that promotes growth, increases yields for grain and fruit crops, and makes plants more resistant to drought and cold weather. Brassinolide was first isolated from rapeseed plant pollen (Brassica napus L.). Related compounds, called brassinosteroids, are found in a wide variety of plants. Brassinolide improves plant growth through improved plant photosynthesis, resistance to cold, water shortage and disease.
