PNH — Solanum lycopersicum

Summary

SlPNH (SOLYC06G072300.4) encodes an Argonaute family protein containing Piwi, PAZ, and RNaseH-like domains, with annotated molecular functions including siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. In tomato, SlPNH is associated with fruit yield and axillary bud formation. The gene is linked to diverse biological processes such as miRNA metabolism, somatic stem cell population maintenance, appendage development, and glutathione anabolism. Associations with traits include style length, lycopene content, leaf morphology, photosynthetic ability, virus resistance, and auxin signalling. Related genes in other species link the family to seed dormancy, leaf colour, flowering time, and histone ubiquitination. Sequence similarity links the family to additional traits including fruit weight, shape, and colour, net photosynthetic rate, and floral organ development.
