TPP1 — Sorghum bicolor
Summary
SORBI_3007G124200 (SbTPP1) on sorghum chromosome 7 encodes a trehalose-phosphatase (EC 3.1.3.12) with trehalase activity, belonging to the trehalose-PPase and HAD-superfamily hydrolase families. The gene is associated with trehalose (mycose) biosynthesis, regulation of secondary shoot formation, and responses to cold, salinity, osmotic stress, oxidative stress, and cadmium. It has been linked to photosynthetic rate, grain yield, coleoptile elongation, root elongation, lateral root formation, primary root growth, auxin accumulation, and submergence. The encoded protein localizes to the nucleolus, cytosol, cytoplasm, and nucleus. Studies of related genes in other species connect the TPP family to drought, salt, and cold stress tolerance, as well as inflorescence branching and meristem determinacy.
