TPS1 — Verticillium dahliae

Summary

VDAG_03989 (VdTPS1) on chromosome DS572700 of Verticillium dahliae encodes a trehalose synthase with trehalose synthase activity (EC 2.4.1.15), trehalose-phosphatase activity, and transglucosylase activity, containing Trehalose_OtsA and Glyco_trans_20 domains. The gene is associated with trehalose biosynthesis and metabolism, melanin anabolism, ascospore formation, penetration peg formation, filamentous growth, autophagy, and cellular responses to desiccation, heat, hydrogen peroxide, and stress. It is linked to vascular wilt disease in Nicotiana benthamiana. Phenotypic associations include increased acquired thermotolerance, decreased hypoosmotic stress resistance, absent biofilm formation and desiccation resistance, abnormal spore germination, and altered cell cycle progression. The protein localises to the trehalose-6-phosphate synthase complex, cytosol, and nucleus.
