The molecular mechanisms of brassinosteroids in plant breeding

Two growth-promoting groups of substances, or phytohormones, the gibberellins and the brassinosteroids are used independently of each other for the breeding and production of crop plants. It is discovered that without brassinosteroids, a plant is unable to produce gibberellins.
