NAC — Lactuca sativa

Summary

LsNAC (LSAT_V11C700350780) on chromosome 7 encodes a NAC domain-containing transcription factor with DNA-binding transcription activator activity. It is associated with the regulation of leaf senescence, root hair elongation, abscisic acid homeostasis, photomorphogenesis, anther development, and responses to hypoxia, sucrose, and fungi. The gene is linked to traits including plant width, leaf length, root thickness, photosynthetic rate, ethylene sensitivity, disease tolerance, and brassinosteroid content. It has been connected to phenotypes such as oxidative stress response, carbon and nitrogen metabolism, abiotic stress tolerance, pathogen susceptibility, drought resistance, and thermomemory. Studies of related genes in other species link the family to drought tolerance, ABA sensitivity, salt stress sensitivity, and enhanced thermotolerance.
