PNH — Capsicum annuum

Summary

CaPNH (T459_07947) on pepper chromosome 3 encodes an argonaute-family protein with multiple annotated molecular functions including siRNA binding, RNA endonuclease activity, and dsRNA binding, as well as histone ubiquitin ligase and deubiquitinase activities, superoxide dismutase activity, and L-ascorbate peroxidase 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 cellular responses to virus and calcium ions. It is linked to traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, root phototropism, flower abscission zone morphology, gibberellic acid and cytokinin content, lignin biosynthesis, inflorescence development, and UV-A and UV-B light sensitivity. Phenotypic associations include leaf polarity, virus resistance, auxin signalling, juvenile-to-adult transition, seed dormancy, germination time, and stomatal index.
