PLC1 — Daucus carota subsp. sativus

Summary

DCAR_028850 (DcPLC1) on carrot chromosome 8 encodes a phosphoinositide phospholipase C (PI-PLC) family protein with phosphatidylinositol-4,5-bisphosphate phospholipase C activity, also annotated for phosphatidylinositol kinase activity, G-actin and F-actin binding, and auxin efflux transporter activity. The gene is associated with calcium ion homeostasis, positive regulation of auxin biosynthesis, GABA biosynthesis, PTI signalling, and response to oomycetes. It is linked to auxin content, photosynthetic rate, oxidative stress response, disease tolerance, root morphology, salt tolerance, and plant growth and development traits. Phenotypic associations include drought escape response, flowering time, thermotolerance, stomatal closure, root gravitropism, and aluminum tolerance. Studies of related genes in other species connect the PLC family to salt and heat stress tolerance, Phytophthora resistance, seed germination, and fertility.
