TPI — Cucumis sativus

Summary

CsTPI (CSA_6G190410) on cucumber chromosome 6 encodes a triosephosphate isomerase, a glycolytic enzyme that interconverts D-glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. The gene is associated with a wide range of metabolic processes, including glycolysis, gluconeogenesis, the Calvin cycle, the TCA cycle, the glyoxylate cycle, and the reductive pentose-phosphate pathway. It has also been linked to carotenoid and chlorophyll metabolism, sucrose metabolism, nitrate assimilation, and secondary metabolism. Associations with agronomic traits include leaf color, plant height, stem diameter, root length, net photosynthetic rate, transpiration rate, stomatal resistance, chlorophyll content, and sucrose content. The encoded protein is predicted to localize to multiple cellular compartments, including the cytosol, chloroplast stroma, mitochondria, apoplast, and plasmodesmata. Studies of related genes in other species connect the triosephosphate isomerase family to carbon and sugar metabolism, male fertility, and stress responses.
