TPP1 — Sorghum bicolor
Summary
SORBI_3002G184600, designated TPP1 on sorghum chromosome 2, encodes a trehalose-phosphatase (EC 3.1.3.12) with trehalase activity, belonging to the HAD-superfamily hydrolase and trehalose-PPase domain families. The gene is associated with mycose (trehalose) biosynthesis, regulation of secondary shoot formation, and responses to oxidative stress, cold, salinity, and cadmium. It has been linked to photosynthetic rate, grain yield, coleoptile elongation, lateral root formation, primary root growth, and auxin accumulation. The encoded protein localises 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, submergence tolerance, inflorescence branching, meristem determinacy, and trehalose metabolism.
