PDF1 — Camelina sativa

Summary

CsPDF1 (CSA17G018650) on Camelina sativa chromosome 17 encodes a protein containing HEAT and ARM-type fold domains, with protein phosphatase regulator activity and protein serine/threonine phosphatase activity. The gene is associated with regulation of phosphorylation, stomatal opening and closure, abscisic acid signaling, reactive oxygen species metabolism, wax and unsaturated fatty acid biosynthesis, sucrose metabolism, and negative regulation of leaf senescence. It localizes to the PP2A complex, nucleus, cytosol, plasma membrane, and cell wall. CsPDF1 is linked to seed yield, biomass yield, water use efficiency, carotenoid content, brassinosteroid content and sensitivity, high temperature stress response, root oxidative activity, leaf elongation rate, and total soluble sugar content. Studies of related genes in other species connect the family to cortical microtubule organization, cell elongation, stomatal development, floral transition, and drought recovery.
