PNH — Capsicum annuum

Summary

CaPNH (T459_18095) on pepper chromosome 6 encodes an Argonaute-family protein with Piwi, PAZ, and RNaseH-like domains, 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 has been linked to numerous agronomic traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, flower development, root phototropism, and responses to UV light and osmotic stress. Phenotypic associations include leaf polarity, virus resistance, auxin signaling, arbuscular mycorrhizal colonization, seed dormancy, and germination time. Related genes in other species connect the family to fruit yield, leaf shape, shoot meristem organization, and heat tolerance.
