PNH — Capsicum annuum

Summary

CaPNH (T459_28281) on pepper chromosome 11 encodes a Piwi/PAZ-domain protein with annotated histone ubiquitin ligase, deubiquitinase, dsRNA-binding, siRNA-binding, RNA endonuclease, and superoxide dismutase activities. It is associated with miRNA and long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, somatic stem cell maintenance, temporal regulation of development, cell fate commitment, and female meiotic nuclear division. The gene is linked to numerous traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, virus resistance, seed dormancy, germination time, root growth, meristem size, flowering time, and responses to UV-A and UV-B light. Studies of related genes in other species connect the family to leaf polarity, auxin signalling, juvenile-to-adult transition, shoot meristem organization, and fruit yield.
