SSA — Sorghum bicolor

Summary

SbSSA (SORBI_3004G357600) on sorghum chromosome 4 encodes a sucrose synthase enzyme (EC 2.4.1.13) with sucrose synthase activity, also annotated for DNA binding transcription factor activity and protein phosphorylated amino acid binding. The gene is associated with sucrose and starch metabolism, glucan anabolism, callose deposition in phloem sieve plates, and responses to hypoxia, anoxia, flooding, sorbitol, mannitol, glucose, sucrose, and nitrate starvation. It is linked to auxin polar transport, ROS metabolism, cell cycle modulation, and DNA damage response. The protein localizes to the cytosol, membrane, plasmalemma, vacuole, plant-type cell wall, chloroplast stroma, plastid, mitochondria, and plasmodesmata. Associations include grain yield, grain filling, starch content, total soluble sugar content, photoperiod sensitivity, brassinosteroid content and sensitivity, auxin sensitivity, high and low temperature stress responses, oxidative stress response, root development, and leaf senescence.
