ENP — Lactuca sativa

Summary

LsENP, located on chromosome 8 of garden lettuce (Lactuca sativa), encodes an NPH3/RPT2-like domain-containing protein with FMN binding, blue light photoreceptor activity, and protein kinase activity. It is associated with the regulation of auxin polar transport, apical protein localization, basipetal auxin transport, and cotyledon vascular tissue pattern formation. The gene 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. It also is associated with phototropism responses, root gravitropism, chloroplast accumulation movement, and responses to red or far-red light. Related genes in other species are linked to phototropic growth, chloroplast migration, and guard cell anion channel regulation.
