MADS4 — Brachypodium distachyon

Summary

BRADI_2G25090V3 (MADS4, also known as BdMADS21) on chromosome 2 of Brachypodium distachyon encodes a MADS-box transcription factor containing a MADS-box/MEF2-like DNA-binding domain and a K-box domain. The protein localises to the nucleus and exhibits RNA polymerase II transcription regulatory region sequence-specific DNA binding, DNA-binding transcription factor activity, and protein dimerization activity. MADS4 is associated with reproductive structure development, organogenesis, photoperiodism, vernalization response, and photoprotection. It has been linked to heading time, anther extrusion, and ovule identity. Studies of related genes in other species connect the family to spikelet number, floral organ identity and number, anthesis time, plant height, leaf number, and seasonality.
