PIA1 — Cucumis sativus

Summary

CsPIA1 (CSA_4G631580) on cucumber chromosome 4 encodes a protein serine/threonine phosphatase (EC 3.1.3.16) with a PP2C domain and PPM-type phosphatase-like domain, also annotated for protein binding and metal binding. This gene is associated with sex determination, flower morphogenesis, regulation of photosynthesis, downregulation of photosynthesis, chlorophyll fluorescence, carotenoid anabolism, hormone anabolism, cell wall modification, fatty acid metabolism, TCA cycle, secondary metabolism, intracellular signal transduction, sumoylation, virus-induced PTGS, and response to salt. It is linked to traits including photosynthetic rate, chlorophyll content, proline content, drought tolerance, and flowering time. The protein localizes to the chloroplast membrane, chloroplast envelope, plastid, mitochondria, cytosol, plasmalemma, membrane, extracellular region, and stress granules. Studies of related genes in other species connect the family to immune response, nuclear import, and traits such as fruit weight, fruit firmness, seed longevity, and plant height.
