PNH — Capsicum annuum

Summary

CaPNH (T459_17910) on pepper chromosome 6 encodes a protein with Piwi, PAZ, and ArgoL domains, characteristic of the Argonaute family, and is annotated with diverse molecular functions including siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. The gene is associated with miRNA and tasiRNA processing, gene silencing, somatic stem cell maintenance, and temporal regulation of development. It is linked to traits such as fruit color, carotenoid content, leaf morphology, photosynthetic ability, flower development, and responses to UV light and osmotic stress. Phenotypic associations include leaf polarity, virus resistance, auxin signaling, seed dormancy, and arbuscular mycorrhizal colonization. Studies of related genes in other species connect the family to developmental timing, organ polarity, shoot meristem organization, and fruit yield.
