PNH — Capsicum annuum

Summary

CaPNH (T459_09942) on pepper chromosome 3 encodes a protein argonaute 1A, a member of the Argonaute family characterized by Piwi, PAZ, and RNaseH-like domains. The gene is associated with siRNA binding, RNA endonuclease activity, and miRNA metabolic processes, as well as gene silencing by miRNA-directed mRNA cleavage. It has been linked to diverse traits including fruit color, carotenoid content, leaf morphology, photosynthetic ability, flower development, and responses to UV light and osmotic stress. Associations also extend to phenotypes such as leaf polarity, virus resistance, auxin signaling, seed dormancy, and juvenile-to-adult transition. Studies of related genes in other species connect the family to fruit yield, leaf shape, shoot meristem organization, and heat tolerance.
