PDF1 — Camelina sativa

Summary

CsPDF1 (CSA03G017130) on Camelina sativa chromosome 3 encodes a protein with PP2A regulatory subunit A and HEAT repeat domains, and is annotated with protein phosphatase regulator activity, protein serine/threonine phosphatase activity, and calcium ion binding. The gene is associated with regulation of phosphorylation, stomatal opening and closure, abscisic acid-mediated signaling, reactive oxygen species metabolism, wax and unsaturated fatty acid anabolism, negative regulation of leaf senescence, and response to thermal stimulus. It localizes to the PP2A complex, nucleus, cytosol, and plasma membrane. Associations include seed yield, biomass yield, water use efficiency, carotenoid content, brassinosteroid content and sensitivity, osmotic response sensitivity, high temperature stress response, cell elongation, and chloroplast development. Studies of related genes in other species link the family to cortical microtubule organization, organ elongation, temperature stress tolerance, and carotenoid accumulation.
