HIR1 — Capsicum annuum

Summary

CaHIR1 (T459_10188) on pepper chromosome 3 encodes a protein containing a Band7/SPFH domain, characteristic of the band 7/mec-2 family. The encoded product is annotated with telomeric repeat binding, histidine kinase binding, and ATP hydrolase activity. CaHIR1 is associated with defence responses, including detection of bacteria, response to oomycetes and fungi, and hypersensitive response programmed cell death (HR-PCD). It is also linked to telomere maintenance, stem cell population maintenance, root meristem growth, and meristem maintenance. The gene has been connected to traits such as bacterial disease response, disease tolerance, flowering time, and seed viability. Localisation evidence places the product at the plasmalemma, tonoplast, plasmodesma, and stress granules, among other compartments. Related genes in other species link it to innate immunity, Pseudomonas syringae resistance, and telomere length regulation.
