HIR1 — Capsicum annuum

Summary

CaHIR1 (T459_01923) on pepper chromosome 1 encodes a hypersensitive-induced response protein 2 containing a Band7/SPFH domain. The gene is associated with telomeric repeat binding, histidine kinase binding, and ATP hydrolase activity. It is linked to detection of bacteria, response to oomycetes and fungi, hypersensitive response programmed cell death (HR-PCD), defence response to bacteria, virus-induced PTGS, meristem maintenance, root meristem growth, and asexual sporulation. Associations also include telomere maintenance via telomerase, DNA condensation, and stem cell population maintenance. The protein localises to the tonoplast, plasmalemma, mitochondria, plastid, Golgi complex, plasmodesma, stress granule, and cytosol. CaHIR1 is associated with bacterial disease response, disease tolerance, seed viability, and flowering time traits. Related genes in other species are linked to effector-triggered immunity, Pseudomonas syringae resistance, osmotic stress tolerance, and telomere length regulation.
