FMA — Arabidopsis thaliana

Summary

AT3G24140 (FAMA) in Arabidopsis thaliana encodes a member of the FAMA/SPEECHLESS/MUTE family of bHLH transcription factors. The gene is associated with numerous biological processes including peptidyl-lysine trimethylation, cellular response to selenium ion, positive regulation of cell wall cellulose biosynthesis, choline anabolism, and flavone metabolism. FAMA has been linked to a wide range of traits such as temperature-sensitive male sterility, rolled leaf, seed volume and shape, root width, seedling cotyledon size, plastochron, drought sensitivity, carbon isotope discrimination, sodium and potassium content, abscisic acid concentration, and fruit quality. It is also connected to phenotypes including root hydraulic conductivity, drought stress tolerance, meristem size, and smaller rosette leaves with deformed pollen and reduced fertility. The gene product localizes to multiple cellular compartments including the cytochrome b6f complex, cell wall, and photosystem I reaction center.
