FAMA — Daucus carota subsp. sativus

Summary

DCAR_012875, designated DcFAMA and also known as BHLH071, BHLH094, BHLH096, and BHLH96, encodes a basic helix-loop-helix (bHLH) transcription factor located on carrot chromosome 4. The protein possesses a bHLH domain and DNA-binding transcription factor activity, localizes to the nucleus, and is associated with protein binding. In carrots, DcFAMA is associated with abscisic acid (ABA) signaling and the regulation of DNA-templated transcription. The gene is linked to pathways involving seed germination and coleoptile growth under submergence, gravitropism, and responses to abiotic stimuli. Associations with germination rate and root length have been noted. Studies of related genes in other species, including members of the FAMA/SPEECHLESS/MUTE family, link this gene family to drought tolerance and other stress-related traits.
