GAMYB — Camelina sativa

Summary

CSA20G008310, also known as GAMYB, CsMYB33 or MYB33, encodes a GAMYB-like transcription factor with sequence-specific DNA-binding activity. In Camelina sativa, this gene is associated with diverse biological processes including miRNA transcription, anther wall tapetum morphogenesis, phlobaphene biosynthesis, pigment accumulation, floral organ senescence, pollen sperm cell differentiation, programmed cell death, and regulation of phenylpropanoid metabolism. It is linked to cell wall organization, protein storage vacuole organization, and defense responses to insects. The encoded protein localizes to the nucleus and plant-type cell wall. Associations with male fertility, anther development, seed germination, drought tolerance, ABA response, root growth, vegetative phase change, and susceptibility to root-knot nematode have been reported. Studies of related genes in other species link the family to flowering time, petiole elongation, and gibberellin signaling.
