ENP — Lactuca sativa

Summary

LsENP on chromosome 7 of garden lettuce encodes an NPH3/RPT2-like protein with a BTB/POZ domain, annotated with blue light photoreceptor activity, FMN binding, and protein kinase activity. The gene is associated with auxin polar transport regulation, apical protein localization, chloroplast accumulation movement, and responses to red or far-red light. It is linked to numerous agronomically relevant traits including biomass yield, seed yield, leaf angle, days to flowering, lateral root number and length, nitrate uptake, submergence tolerance, leaf yellowing tolerance, and viral disease response. Studies of related genes in other species connect the family to phototropism, organogenesis, cotyledon formation, root gravitropism, and PIN auxin exporter polarity.
