ACT — Camelina sativa

Summary

CSA01G021690 (ACT, also known as CsFIZ2, LSR2, CsENL2, CsACT2, CsDER1, CsLSR2, FIZ2, ACT2, ENL2, DER1) on Camelina sativa chromosome 1 encodes a structural constituent of the cytoskeleton, belonging to the actin/actin-like superfamily with ATPase and hydrolase activity and ATP binding. The gene is associated with actin gel formation, root epidermal cell differentiation, root hair tip growth, pollen germination, and responses to salt, high light intensity, red and far-red light, and cytokinin. It is linked to starch, unsaturated fatty acid, and triglyceride anabolism, as well as lipid and secondary metabolism, detoxification, and NO storage. The protein localizes to the actin cytoskeleton, cytosol, cytoplasm, nucleus, and the Cul4-RING E3 ubiquitin ligase complex. Associations with seed length, weight, size, linolenic acid content, harvest index, photosynthetic rate, germination rate, root length, and root morphology traits have been observed. Related genes in other species link the family to actin filament organization, root hair development, cell elongation, and auxin distribution.
