PNH — Cucumis melo

Summary

MELO3C012127.2, designated CmPNH on melon chromosome 11, encodes a protein with Piwi and Argonaute domains, characteristic of the Argonaute family, and is annotated with diverse molecular functions including dsRNA binding, siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase and deubiquitinase activities. The gene is associated with miRNA and siRNA metabolic processes, gene silencing by miRNA-directed mRNA cleavage, somatic stem cell population maintenance, and temporal regulation of development. It has been linked to numerous traits including leaf and flower morphology, fruit position, pedicel and stamen length, gibberellic acid and cytokinin content, photosynthetic ability, and responses to UV-A and UV-B light. Associations also include leaf polarity, virus resistance, auxin signalling, arbuscular mycorrhizal fungal colonization, juvenile-to-adult transition, seed dormancy, and germination time. Related genes in other species are associated with histone ubiquitination, early flowering, pale leaves, and reduced seed dormancy.
