Gibberellic Acid Production by Fungi- A Review

Abstract

The gibberellins (GAs) are one of the major groups of growth promoting hormones, which play an essential role in regulation of growth and development of angiospermic plants. Gibberellins are diterpenoid acids biologically derived from tetracyclic diterpenoid hydrocarbons and produced in good quantity by microorganism. A number of micro-organisms have been reported to produce GA3 and GA like substances. Among these, the fungal cultures are able to produce GA like activities in higher yields. These GA producing fungal species could be exploited well to meet with the growing demands of exogenous GA for the agricultural crops to increase yield.
