NPR1 — Solanum tuberosum

Summary

PGSC0003DMG401000923, designated NPR1 (also known as NPR3, StNPR1, or StNPR3) on potato chromosome 7, encodes a protein containing BTB/POZ, ankyrin repeat, and NPR1/NIM1-like C domains, with transcription cis-regulatory region binding and protein homodimerization activities. In potato, NPR1 is associated with osmotic stress tolerance, pathogen defense, immune response, and resistance to Ralstonia solanacearum. The gene is linked to regulation of salicylic acid- and jasmonic acid-mediated signaling pathways, systemic acquired resistance, induced systemic resistance, and responses to herbivores and symbiotic bacteria. It localizes to the nucleus, cytoplasm, and plasma membrane. Associations also include stipule, leaf, and flower development, cell differentiation, and traits such as photosynthetic rate, disease tolerance, and aphid resistance. Related genes in other species are linked to bacterial leaf spot resistance, bacterial wilt resistance, and virus resistance.
