The Chemical Structures and Occurrence of Brassinosteroids in Plants

  • Chapter
Brassinosteroids

Abstract

Brassinosteroids are plant hormones with high-promoting activity. Brassinosteroids are hydroxylated derivatives of cholestane and their structural variations comprise the substitution pattern at rings A and B as well as the C-17 side chain. They can be classified as C27, C28, and C29 compounds, depending on the alkyl-substitution pattern of side chain. Up to now 65 free brassinosteroids and 5 brassinosteroid conjugates have been characterized. This chapter gives a comprehensive survey on the hitherto known brassinosteroids isolated from lower and higher plants. The occurrence of brassinosteroids has been demonstrated in almost every part of plants such as pollen, flower, shoot, vascular cambium, leaf, fruit, seed, and root.
