FMA — Daucus carota subsp. sativus

Summary

DCAR_026607 (FMA, DcFMA) on carrot chromosome 8 encodes a protein belonging to the FAMA/SPEECHLESS/MUTE family, containing a bHLH domain and an ACT domain. The product is annotated with delta3,5-delta2,4-dienoyl-CoA isomerase activity and numerous other molecular functions. In carrot, the gene is associated with diverse biological processes including peptidyl-lysine trimethylation, cellular response to selenium ion, positive regulation of cell wall cellulose biosynthesis, choline anabolism, and triglyceride breakdown. It is linked to traits such as calcium sensitivity, seedling cotyledon size, total soluble sugar content, abscisic acid concentration, fruit quality, water stress response, cadmium concentration, cellulose content, and wheat powdery mildew disease response. The gene is also associated with phenotypes including drought stress tolerance, seed germination under cold stress, and root hydraulic conductivity. Studies of related genes in other species connect the family to stomata formation, water use efficiency, and male fertility.
