ACT — Camelina sativa

Summary

CSA19G026200 (ACT, also known as CsFIZ2, LSR2, CsENL2, CsACT2, CsDER1, CsLSR2, FIZ2, ACT2, ENL2, DER1) in Camelina sativa encodes an actin structural constituent of the cytoskeleton with ATP-binding, hydrolase and protein-binding activities. The gene is associated with actin gel formation, root epidermal cell differentiation, root hair tip growth, and localizes to the actin cytoskeleton, cytosol, cytoplasm, nucleus and the Cul4-RING E3 ubiquitin ligase complex. It is linked to starch, unsaturated fatty acid, triglyceride and secondary metabolism, detoxification, responses to high light, red and far-red light, cytokinin and salt, pollen germination, and NO storage. Associations with seed length, weight and size, linolenic acid content, harvest index, photosynthetic rate, germination rate, root length and morphology have been reported. Related genes in other species link the family to actin filament organization, root hair development, cell elongation, auxin distribution, and vegetative development.
