FTA — Medicago truncatula

Summary

MTR_2G098650, designated FTA (MtFTA), encodes a protein with a Prenyl_trans_a domain and possesses protein farnesyltransferase, geranylgeranyltransferase, and prenyltransferase activities. The gene is associated with protein farnesylation, geranylgeranylation, and palmitoylation. FTA is linked to diverse biological processes including seed and leaf abscission, auxin transport, petal morphogenesis, cuticle development, and regulation of osmotic stress and salinity responses. The gene has been connected to numerous agronomically relevant traits such as seed yield, seed protein content, biomass yield, flowering time, disease tolerance, phosphorus uptake, root hair length, stomatal regulation, and drought tolerance. It is associated with heterotrimeric G-protein complex and polarized growth sites, and studies of related genes in other species link the family to abscisic acid signaling, root architecture, and meristem development.
