APS1 — Brassica juncea

Summary

BJUA01G30290S (symbol APS1, also known as BjPUB35) on chromosome A01 of Indian mustard (Brassica juncea) encodes a protein with acid phosphatase activity, ubiquitin ligase activity, transmembrane receptor protein serine/threonine kinase activity, and nutrient reservoir activity, containing U-box and protein kinase domains. This gene is associated with protein ubiquitination, innate immunity, detection of symbiotic fungi, glutathione anabolism, sulfur metabolism, flower morphogenesis, stomatal complex development, sepal giant cell differentiation, embryo sac development, and regulation of asymmetric cell division. It localizes to the plasma membrane, nucleus, and multivesicular body membrane. The gene is linked to ABA signaling, salinity and osmotic stress tolerance, seed germination, phosphate starvation response, and salt tolerance. Related genes in other species are linked to abscisic acid sensitivity and photochemical quenching.
