SUS4 — Zea mays

Summary

ZM00001EB016290 (SUS4, ZmSUS4) on maize chromosome 1 encodes a sucrose synthase enzyme (EC 2.4.1.13) with sucrose synthase activity, containing sucrose synthase and glycosyltransferase domains. The gene is associated with sucrose breakdown, carbohydrate derivative breakdown, phloem loading, energy homeostasis, response to anoxia, response to water, and mitochondria localization. It is also linked to ear development, cell maturation, histogenesis, cell fate determination, hormone anabolism, gluconeogenesis, proline metabolism, protein tetramerization, and protein processing. Trait associations include grain yield, grain weight, grain number, grain size, grain appearance, grain filling period, starch content, sucrose content, sugar content, cellulose content, seed longevity, seed dormancy, root length, growth stage, cold tolerance, and drought tolerance.
