ENP — Lactuca sativa

Summary

LsENP, located on lettuce chromosome 7, encodes an NPH3/RPT2-like protein containing BTB/POZ and NPH3 domains, with annotated molecular functions including FMN binding, blue light photoreceptor activity, and protein kinase activity. The gene is associated with auxin polar transport regulation, apical protein localization, chloroplast accumulation movement, and response to red or far-red light. It localizes to the apical plasma membrane, CRL complex, and ubiquitin ligase complex. LsENP is linked to numerous agronomically relevant traits including biomass yield, seed yield, leaf angle, leaf yellowing tolerance, submergence tolerance, viral disease response, days to flowering, lateral root number and length, root mass density, nitrate uptake, and phototropism responses. Studies of related genes in other species connect the NPH3/RPT2-like family to phototropic growth, chloroplast migration, stomatal aperture regulation, and embryo development.
