SUS4 — Sorghum bicolor

Summary

SORBI_3001G378300, designated SbSUS4 on sorghum chromosome 1, encodes a sucrose synthase enzyme (EC 2.4.1.13) with sucrose synthase activity, belonging to the SUS_EPBD, SUS_N, and Glyco_trans_1 domain families. This gene is associated with sucrose metabolism, glucan anabolism, protein tetramerization, and responses to anoxia and salt stress. It is linked to seed maturation, grain filling period, and sugar content. Additional associations include nodulation, autotrophy, protein synthesis, and lipid metabolism. Related genes in other species connect the family to grain yield, grain weight, grain size, grain number, grain appearance, starch content, cellulose content, sucrose content, seed longevity, seed dormancy, seed germination, root length, growth stage, cold tolerance, and drought tolerance.
