PNH — Cucumis sativus

Summary

CsPNH (CSA_5G606440) on cucumber chromosome 5 encodes a protein with Piwi and Argonaute domains, including PAZ and RNaseH-like superfamily domains, and is annotated with diverse molecular functions such as dsRNA binding, siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. The gene is associated with miRNA and siRNA metabolic processes, gene silencing by miRNA, somatic stem cell population maintenance, and temporal regulation of development. It has been linked to traits including leaf morphology, leaf polarity, male flowering, flower abscission zone morphology, fruit position, pedicel length, seed viability, photosynthetic ability, and responses to UV-A and UV-B light. Related genes in other species connect the family to leaf shape, developmental timing, floral organ development, shoot meristem organization, fruit yield, and viral disease response.
