SOC1A — Medicago truncatula

Summary

MTR_7G075870, designated MtSOC1A or MADS50 in barrel medic (Medicago truncatula) on chromosome 7, encodes a MADS-box transcription factor containing a K-box domain and MEF2-like domain. The product binds DNA, dimerizes, and acts as an RNA polymerase II-specific transcription factor. MtSOC1A is associated with regulation of vernalization response, floral organ identity and development, floral meristem determinacy, stamen formation, carpel development, integument development, and seed growth. It localizes to the nucleus. Studies of related genes in other species link the family to floral transition and meristem identity, though these functions are not directly established for MtSOC1A.
