NAC — Lactuca sativa

Summary

LsNAC, encoded by the lettuce gene LSAT_V11C700350770 on chromosome 7, is a NAC-domain transcription factor with DNA-binding and 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 has been linked to traits including plant width, leaf length, photosynthetic rate, ethylene sensitivity, disease tolerance, and brassinosteroid content, as well as phenotypes such as oxidative stress response, carbon and nitrogen metabolism, drought resistance, and pathogen susceptibility. Studies of related genes in other species connect the family to drought tolerance, salt stress sensitivity, thermomemory, and resistance to bacterial pathogens.
