PLC1 — Daucus carota subsp. sativus

Summary

DCAR_005889 (DcPLC1) on carrot chromosome 2 encodes a phosphoinositide phospholipase C (PI-PLC) family protein with phosphatidylinositol-4,5-bisphosphate phospholipase C activity, also annotated for phosphatidylinositol kinase activity, actin binding, and auxin efflux transporter activity. The gene is associated with calcium ion homeostasis, GABA biosynthesis, positive regulation of auxin biosynthesis, and PTI signalling. It has been linked to auxin content, photosynthetic rate, oxidative stress response, disease tolerance, root morphology, and salt tolerance. Associations include thermotolerance, stomatal closure, drought escape response, flowering time, embryo development, root gravitropism, and aluminum tolerance. Related genes in other species connect the PLC family to heat and salt tolerance, Phytophthora resistance, and phosphoinositide signalling.
