NPR1 — Daucus carota subsp. sativus

Summary

DCAR_003797, the carrot NPR1 gene on chromosome 1, encodes a protein with an NPR domain and an NPR1/NIM1-like C-terminal region that binds zinc. In carrot, this gene is associated with systemic acquired resistance and the regulation of salicylic acid- and jasmonic acid-mediated signaling pathways. It has been linked to defence responses against bacteria and fungi, as well as to herbivore response. Additional associations include embryogenesis, responses to thirst and salinity, and localisation to the nucleus, cytoplasm and nuclear bodies. Studies of related genes in other species connect this gene family to plant immunity and systemic defence signalling.
