PNH — Cucumis sativus

Summary

CsPNH (CSA_1G031900) on cucumber chromosome 1 encodes a eukaryotic translation initiation factor 2c protein with multiple Argonaute domains including Piwi, PAZ, and RNaseH-like superfamily domains. The gene is associated with siRNA binding, RNA endonuclease activity, and miRNA metabolic processes, as well as somatic stem cell population maintenance, gene silencing by miRNA-directed mRNA cleavage, and temporal regulation of development. CsPNH is linked to traits including leaf morphology and polarity, male flowering, flower abscission zone morphology, pedicel length, fruit position, seed viability, and photosynthetic ability. The gene is also connected to phenotypes such as virus resistance, auxin signalling, juvenile-to-adult transition, and reduced seed dormancy. Studies of related genes in other species link the family to shoot meristem organization, leaf development, floral organ identity, and fruit yield traits.
