Brassinosteroids : a new class of plant hormones

Plants possess the ability to biosynthesize a large variety of steroids, but it was not until 1979 that a hormonal function was demonstrated in plants. Today, about 40 structurally and functionally related steroids, known as brassinosteroids, have been isolated from natural sources. Brassinosteroids...
