SPS1F — Glycine max

Summary

GmSPS1F (GLYMA_13G161600V4) on soybean chromosome 13 encodes a protein with sucrose-phosphate synthase, sucrose-phosphate phosphatase, sucrose synthase, and protein phosphatase activities, containing SPS_pln, SPS_C, SPP-like_dom, Sucrose_synth_GT-B1, Glyco_trans_1, and HAD_sf domains. The gene is associated with sucrose anabolism and breakdown, starch and cellulose anabolism, proline and glutathione metabolism, nitrogen fixation, desiccation tolerance acquisition, nectar secretion, and water transport. It localizes to the cytosol, nucleus, endoplasmic reticulum, plasmodesmata, and plasma membrane. Associations include leaf area duration, stem strength, net photosynthetic rate, seed yield and weight, sugar and starch content, chlorophyll content, vegetative vigor, heterosis, shoot branching, root phototropism, and brassinosteroid sensitivity. Studies of related genes in other species link the family to sucrose synthesis, ABA-regulated gene expression, stomatal response, and susceptibility to Botrytis cinerea and Pseudomonas syringae.
