SH1 — Zea mays

Summary

ZM00001EB134520 (ZmSH1, also known as ZmYAB6) encodes a protein containing YABBY and HMG-box domains, with DNA-binding and zinc-binding activity. The protein localises to the nucleus and is associated with regionalization, abaxial cell fate specification, carpel and style development, floral meristem determinacy, and regulation of shoot apical meristem and leaf development. ZmSH1 is linked to sucrose metabolism, including both anabolism and breakdown, as well as cellulose anabolism. At the trait level, the gene is associated with seed shattering, grain weight, ear weight, seed size, starch and amylose content, protein content, heterosis, and grassy flavor. Related genes in other species are associated with shattering and seed-related phenotypes.
