FHA — Oryza sativa Indica Group

Summary

BGIOSGA008648 (OiFHA, also known as OiCRY2) on chromosome 2 of Indica rice encodes a cryptochrome/photolyase family protein with DNA (6-4) photolyase activity, CPD photolyase activity, histone kinase activity, and blue, red, and far-red light photoreceptor activities. This gene is associated with regulation of post-embryonic development, photoreactive repair, photoentrainment of the circadian clock, mRNA transcription, response to strigolactone, anthocyanin metabolism, and positive regulation of ROS metabolic processes. It has been linked to traits including photoperiod-sensitive flowering time, photosynthetic ability, spikelet fertility, seed shattering, leaf morphology, molybdenum and phenolic compound content, and responses to light quality, temperature stress, and glyphosate. The protein localizes to the nucleus, cytosol, plasmalemma, mitochondria, and plant-type vacuole. Studies of related genes in other species connect the family to photoperiodic flowering, circadian clock entrainment, photomorphogenic development, and stress responses.
