GAMYB — Camelina sativa

Summary

CSA08G058440, also known as GAMYB, CsMYB33, or MYB33, encodes a GAMYB-like transcription factor with sequence-specific DNA binding activity. This gene is associated with miRNA transcription, anther wall tapetum morphogenesis, phlobaphene biosynthesis, pigment accumulation, protein storage vacuole organization, pollen sperm cell differentiation, and regulation of lignin anabolism. It is linked to upregulation of phytoalexin biosynthesis, defense response to insects, programmed cell death, and abscisic acid-mediated signaling, as well as downregulation of growth and cell proliferation. The encoded protein localizes to the nucleus. Phenotypic associations include male fertility, anther development, ABA response and sensitivity, seed germination, root growth, drought tolerance, vegetative phase change, and susceptibility to root-knot nematode. Related genes in other species link the family to flowering time, petiole elongation, and gibberellin signaling.
