NAM — Solanum tuberosum

Summary

PGSC0003DMG400012403, the potato NAM gene (also known as StNAC098, StCUC1 or CUC1) on chromosome 7, encodes a NO APICAL MERISTEM (NAC) domain transcription factor that binds sequence-specific DNA and cis-regulatory regions, homodimerizes, and localizes to the nucleus and endoplasmic reticulum. The gene is associated with leaflet formation, organ boundary specification, meristem initiation, secondary shoot formation, and regulation of endosperm development. It has been connected to numerous agronomic traits including leaflet morphology, leaf margin serration, shoot branching, seed yield, root length, chlorophyll content, water use efficiency, and drought tolerance. Related genes in other species are linked to cotyledon separation, floral organ separation, embryonic shoot meristem formation, and leaf serration.
