NAC — Asparagus officinalis

Summary

AoNAC (A4U43_C02F6640) on asparagus chromosome 2 encodes a NAC domain-containing transcription activator with DNA-binding and protein homodimerization activity. It is associated with the regulation of root hair elongation, endosperm development, leaf senescence, photomorphogenesis, anther development, and lignin anabolism. The gene is linked to responses to hypoxia, salt, sucrose, and fungal defence, as well as downregulation of abscisic acid mediated signaling. Associations include traits such as brassinosteroid content, ethylene sensitivity, photosynthetic rate, chlorophyll content, leaf senescence, root thickness, disease tolerance, and seedling growth. Related genes in other species link the family to drought tolerance, thermomemory, pathogen resistance, and oxidative stress responses.
