PDF1 — Brassica juncea

Summary

BjPDF1 (BJUB04G42420S) on Indian mustard chromosome B04 encodes a protein with protein phosphatase regulator activity, protein serine/threonine phosphatase activity, calcium ion binding, kinase activity, DNA binding transcription factor activity, and chaperone protein binding. The product belongs to the PP2A regulatory subunit A family, containing HEAT and ARM-type fold domains. This gene is associated with regulation of phosphorylation, stomatal opening and closure, abscisic acid-mediated signaling, reactive oxygen species metabolism, leaf senescence, glucosinolate and sucrose metabolism, microtubule and cortical cytoskeleton organization, and responses to thermal stimulus and carbon dioxide. It localizes to the PP2A complex, nucleus, cytosol, plasma membrane, and cell wall. Associations include seed yield, biomass, water use efficiency, carotenoid content, brassinosteroid sensitivity, chloroplast development, cell elongation, and high temperature stress response. Related genes in other species are linked to cytoskeleton organization, stomatal development, floral transition, and temperature stress tolerance.
