Summary

BJUB03G54740S (BjPHR1) on chromosome B03 of Indian mustard encodes a class 2 DNA photolyase with CPD photolyase activity, FAD and DNA binding, and is annotated to photoreactive repair, UV protection, mating and organogenesis. The gene is associated with cyclobutane pyrimidine dimer photoreactivation, UV damage repair, and ultraviolet-B sensitivity. BjPHR1 is associated with phosphate starvation response, phosphorus homeostasis, phosphate uptake and sensing, drought tolerance, iron and sulfate homeostasis, anthocyanin accumulation, lateral root formation, hypoxia response, arsenate detoxification, carbon metabolism, triacylglycerol accumulation, jasmonate response, pathogen resistance, and heterosis. The encoded protein localises to the plastid, cytoplasm and nucleus. Studies of related genes in other species link the family to phosphate signaling, leaf senescence, flowering time, photosynthesis efficiency, and root hair traits.
