PNH — Capsicum annuum

Summary

CaPNH (T459_24113) on pepper chromosome 9 encodes a protein with Argonaute, Piwi, PAZ and RNaseH-like domains, and is annotated with diverse molecular functions including siRNA binding, RNA endonuclease activity, histone ubiquitin ligase and deubiquitinase activities, superoxide dismutase and L-ascorbate peroxidase activities, and DNA-binding transcription activator activity. The gene is associated with miRNA and long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, somatic stem cell population maintenance, temporal regulation of development, cell fate commitment, and protein monoubiquitination. It is linked to numerous traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, root phototropism, virus resistance, seed dormancy, germination time, and responses to UV-A and UV-B light. Related genes in other species are linked to histone ubiquitination, early flowering, pale leaves, and reduced seed dormancy.
