Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence. GAs are one of the longest-known classes of plant hormone. It is thought that the selective breeding of crop strains that were deficient in GA synthesis was one of the key drivers of the "green revolution" in the 1960s, a revolution that is credited to have saved over a billion lives worldwide.

Momilactone B is an allelopathic agent produced from the roots of rice. It has been shown to be produced in high concentrations by the roots of rice seedlings. The production of momilactone B has also been induced in response to infection by blast fungus or irradiated with UV light. More recently it has been shown to be a potential chemotherapeutic agent against human colon cancer.
In molecular biology, this protein domain belongs to the terpene synthase family (TPS). Its role is to synthesize terpenes, which are part of primary metabolism, such as sterols and carotene, and also part of the secondary metabolism. This entry will focus on the N terminal domain of the TPS protein.
