Abstract
Plant steroid hormones, brassinosteroids (BRs), were originally isolated from extracts of pollen because of their growth-promoting properties and their potential use for enhancing crop production. Mutants in the biosynthesis, metabolism, and signaling of brassinolide (BL), the most bioactive BR, are important resources in helping to establish BRs’ essential role in plant growth and development. The dark green and distinctive dwarf phenotype of BR-related mutants identified in pea, tomato, and rice highlights the importance of BRs in crops. These mutants are helping to elucidate both the conserved and the unique features of BR biosynthesis and signaling. Such insights are providing the key knowledge and understanding that will enable the development of strategies towards the production of crops with enhanced qualities.
