FUL — Arabidopsis thaliana

Summary

AT5G60910, known as FUL, FRUITFULL, or AGL8, encodes a MADS-box transcription factor that localises to the nucleus and binds sequence-specific DNA to regulate transcription. In Arabidopsis thaliana, FUL is associated with fruit morphogenesis, dehiscence, and abscission, as well as carpel and floral organ identity, meristem determinacy, and inflorescence development. The gene has been connected to numerous traits including fruit yield, seed yield, silique morphology, shattering resistance, flower and petal morphology, stem length, leaf area index, branch angle, photoperiod-sensitive flowering time, and heterosis. Phenotypic associations include valve tissue differentiation, silique elongation and dehiscence, carpel development, inflorescence meristem arrest, and drought tolerance. Studies of the related gene AP1 link the family to cauline leaf development and global proliferative arrest.
