RA3 — Sorghum bicolor

Summary

SORBI_3002G381600 (RA3, also known as SbTPP1) encodes a trehalose-phosphatase enzyme (EC 3.1.3.12) with trehalase activity, belonging to the HAD-superfamily hydrolase IIB and OTSB-like protein families. In sorghum, this gene is associated with mycose biosynthesis, regulation of secondary shoot formation, glutathione and sucrose metabolism, and responses to cadmium, oxidative stress, osmotic conditions, salinity, and cold. It is linked to signal transduction and localizes to the nucleolus, cytosol, cytoplasm, and nucleus. The gene has been connected to photosynthetic rate, grain yield, coleoptile and root elongation, lateral root formation, auxin accumulation, and submergence. Studies of related genes in other species link the trehalose-6-phosphate phosphatase family to drought, salt, and cold stress tolerance, root development, starch mobilization, and inflorescence branching.
