TPP1 — Sorghum bicolor

Summary

SORBI_3004G293500, designated TPP1 (also known as TPP4–9, TPPA–C, TPPG, TPPJ, and SbTPPI), encodes a trehalose 6-phosphate phosphatase (EC 3.1.3.12) on sorghum chromosome 4. The protein belongs to the trehalose-phosphatase family and contains HAD-like and OTSB-like domains. This gene is associated with mycose biosynthesis, regulation of secondary shoot formation, glutathione and sucrose metabolism, phenylpropanoid and lignin anabolism, homeostasis, salinity response, cold response, and signal transduction. It has also been linked to protein content and salt tolerance (SALTTL). Studies of related genes in other species connect the family to trehalose metabolism and stress responses, though these associations are not yet established for sorghum.
