Alfa Chemistry - Gibberellins as Plant Growth Regulators

Gibberellins (GAs) are tetracyclic diterpene carboxylic acids that are present in nature and act as plant hormones to control several developmental processes in plants. The majority of them have carbon skeletons made of ent-gibberellane (C20) or ent-20-norgibberellane (C19). They participate in a number of biological processes in plants, including stem lengthening, germination, dormancy, flowering, the growth of flowers, and the withering of leaves and fruits. GAs mutants played a key role during the Green Revolution thanks to their sturdier semi-dwarf stature that can increase yields.
