AG — Zea mays

Summary

ZM00001EB284010 (ZAG1) on maize chromosome 6 encodes a MADS-box transcription factor containing a MADS-box and K-box domain. It is associated with RNA polymerase II transcription regulatory region sequence-specific DNA binding and protein dimerization activity. The gene is linked to floral organ identity, including carpel and stamen specification, floral whorl development, and ear development. It has been connected to traits such as inflorescence branching, flower morphology, plant male sterility, seed longevity, amylose content, and photoperiod-sensitive flowering time. Localisation evidence places the product in the stigma papilla, endosperm protein body, and chloroplast thylakoid membrane. Studies of related genes in other species link the family to stamen identity, ovule development, fruit development, and seed oil accumulation.
