PSY — Glycine max

Summary

GmPSY (GLYMA_02G240200V4) on soybean chromosome 2 encodes a protein with squalene synthase activity, phytoene synthase activity, dimethylallyltransferase activity, farnesyltranstransferase activity, and protein binding. The product belongs to the trans-isoprenyl diphosphate synthase family and is associated with carotenoid anabolism, abscisic acid anabolism, pigmentation, chromoplast organization, chloroplast organization, seed development, photomorphogenesis, de-etiolation, chlorophyll fluorescence, and the ascorbate-glutathione cycle. It localizes to plastids, chloroplast membranes, etioplasts, chromoplast stroma, mitochondria, cytosol, and nucleus. The gene is linked to alpha-carotene content, carotene content, biomass yield, photosynthetic rate, drought tolerance, salt tolerance, oxidative stress response, flowering time, seed dormancy, and cell elongation. Related genes in other species are linked to carotenoid accumulation, provitamin A content, thermotolerance, flowering time, and leaf virescence.
