PNH — Cucumis melo

Summary

MELO3C004836.2 (CmPNH) on melon chromosome 13 encodes a protein with Argonaute, Piwi, and PAZ domains, and is annotated with diverse molecular functions including siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. The gene is associated with miRNA and siRNA metabolic processes, gene silencing by miRNA, and somatic stem cell population maintenance. It has been linked to numerous traits including leaf and flower morphology, fruit position, pedicel and peduncle length, lignin biosynthesis, photosynthetic ability, root phototropism, and responses to UV-A and UV-B light. Associations with phenotypes include leaf polarity, virus resistance, auxin signalling, arbuscular mycorrhizal fungal colonization, juvenile-to-adult transition, seed dormancy, and germination time. Studies of related genes in other species connect the family to leaf morphology, fruit yield, floral organ development, and heat tolerance.
