TPP1 — Sorghum bicolor
Summary
SORBI_3004G232900 (TPP1) on sorghum chromosome 4 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 biosynthesis, regulation of secondary shoot formation, and responses to oxidative stress, cold, salinity, and cadmium. It is linked to photosynthetic rate, grain yield, coleoptile elongation, root growth, lateral root formation, and auxin accumulation. The encoded protein localizes to the cytosol, nucleus, and nucleolus. Studies of related genes in other species connect the TPP family to trehalose-6-phosphate phosphatase activity, trehalose metabolism, and stress tolerance traits including drought, cold, and salt tolerance, as well as inflorescence branching and meristem determinacy.
