FHA — Brassica juncea

Summary

BjFHA (BJUB03G58530S) on chromosome B03 of Indian mustard encodes a cryptochrome/photolyase family protein with blue, red and far-red light photoreceptor activity, histone H3T3 kinase activity, DNA photolyase activity and bHLH transcription factor binding. It is associated with regulation of post-embryonic development, circadian clock photoentrainment, mRNA transcription, photoreactive repair, response to strigolactone, hydrogen peroxide signalling, leaf morphogenesis, and flowering under short days. The gene is linked to numerous agronomic traits including biomass yield, photosynthetic ability, phosphorus uptake, molybdenum and phenolic compound content, leaf angle and temperature, starch grain synthesis, glyphosate sensitivity, and responses to light quality, temperature stress, viral disease and biotic stress. Phenotypic associations include delayed or early flowering, reduced seed production, altered hypocotyl growth, leaf expansion, drought stress response, pathogen resistance, and brassinosteroid and nitrate signalling. Studies of related genes in other species connect the family to photomorphogenesis, circadian clock entrainment, photoperiodic flowering, seed dormancy, biomass production, and stress tolerance.
