FLM — Arabidopsis thaliana

Summary

AT1G77080, also known as FLM (FLOWERING LOCUS M) or MAF1, encodes a MADS-box transcription factor in Arabidopsis thaliana. The protein contains MADS-box and K-box domains and exhibits sequence-specific DNA binding, transcription regulatory region binding, and protein dimerization activities. FLM is associated with thermoregulation, regulation of short-day photoperiodism and flowering, floral whorl development, floral organ formation, and organ induction. It is linked to petal number, size, and morphology, inflorescence branching, stem length, seed protein content, leaf area index, and responses to copper, aluminum, and acid sensitivity. FLM localizes to the nucleus and is associated with regulation of salicylic acid metabolic process and downregulation of systemic acquired resistance. Studies of related genes in other species link the family to additional traits including seed weight, chlorophyll content, and vernalization response.
