NAC — Asparagus officinalis

Summary

AoNAC (A4U43_C10F8630) on asparagus chromosome 10 encodes a NAC domain-containing protein with DNA-binding transcription activator activity, protein homodimerization activity, and histidine kinase binding. This gene is associated with regulation of leaf senescence, root hair elongation, abscisic acid homeostasis, lignin anabolism, and responses to salt, hypoxia, and sucrose. It has been linked to traits including chlorophyll content, photosynthetic rate, ethylene sensitivity, brassinosteroid content, disease tolerance, seedling growth, and root thickness. The product localizes to the nucleus and cytoplasm. Studies of related genes in other species connect the NAC family to drought tolerance, salt stress sensitivity, thermomemory, pathogen resistance, and fruit ripening, and to resistance to Pseudomonas syringae.
