PLC1 — Daucus carota subsp. sativus

Summary

DCAR_024021, designated DcPLC1 on carrot chromosome 7, encodes a phosphoinositide phospholipase C (PI-PLC) family protein with phosphatidylinositol-4,5-bisphosphate phospholipase C activity, containing EF-hand-like, C2, and catalytic X/Y domains. 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 and sensitivity, photosynthetic rate, oxidative stress response, disease tolerance, root morphology, salt tolerance, and plant growth and development traits. Associations include plasma membrane morphology, root gravitropism, stomatal closure, drought escape response, flowering time, and thermotolerance. Related genes in other species connect the PLC family to phosphoinositide signalling, salt and heat stress tolerance, defense responses, and reproductive development.
