PLC1 — Daucus carota subsp. sativus

Summary

DCAR_010467 (DcPLC1) on carrot chromosome 3 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, PTI signalling, and responses to oomycetes and cadmium. It has been linked to auxin content and sensitivity, photosynthetic rate, oxidative stress response, disease tolerance, root morphology, and salt tolerance. Associations with plasma membrane morphology, thermotolerance, embryo development, root gravitropism, stomatal closure, drought escape, flowering time, and aluminum tolerance have been noted. Studies of related genes in other species connect the PLC family to phosphoinositide signalling, heat and cold tolerance, dehydration tolerance, salt stress, and defence against pathogens including Botrytis and Phytophthora.
