SH1 — Zea mays

Summary

ZmSH1 (ZM00001EB032110) on maize chromosome 1 encodes a YABBY family protein with DNA-binding and zinc-binding activity, localised to the nucleus. The gene is associated with regionalization, abaxial cell fate specification, carpel and style development, floral meristem determinacy, and regulation of leaf and shoot apical meristem development. It has also been linked to sucrose and cellulose metabolism, translation initiation, and mitochondrial localisation. On the trait side, ZmSH1 is associated with seed shattering, grain weight, grain yield, ear weight, seed size, starch and amylose content, protein content, and heterosis. Related genes in other species are linked to shattering and seed-related phenotypes.
