PNH — Capsicum annuum

Summary

CaPNH (T459_01911) on pepper chromosome 1 encodes a protein with Piwi and Argonaute domains, including PAZ and RNaseH-like motifs, and is annotated with RNA endonuclease activity, siRNA binding, and histone ubiquitin ligase activity. The gene is associated with miRNA and tasiRNA processing, gene silencing by miRNA-directed mRNA cleavage, somatic stem cell maintenance, and temporal regulation of development. It has been linked to traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, virus resistance, auxin signalling, seed dormancy, and germination time. Studies of related genes in other species connect the family to leaf polarity, juvenile-to-adult transition, shoot meristem organization, organ polarity, fruit yield, and axillary bud formation.
