TPP1 — Sorghum bicolor

Summary

SORBI_3K044415, designated SbTPP1, encodes a trehalose-phosphatase with trehalase activity. The gene is associated with mycose biosynthesis, glutathione and sucrose metabolism, phenylpropanoid and lignin anabolism, and responses to cadmium, oxidative stress, osmotic conditions, and salinity. It is linked to signal transduction and localizes to the nucleolus, cytosol, cytoplasm, and nucleus. SbTPP1 is associated with photosynthetic rate, grain yield, coleoptile and root elongation, lateral root formation, auxin accumulation, and submergence response. Studies of related genes in other species link the family to drought, salt, and cold stress tolerance, water use efficiency, starch mobilization, and inflorescence branching, though these associations are not yet established in sorghum.
