ANAC2 — Oryza sativa Japonica

Summary

OS01G0884300 (ANAC2/OsNAC6) on rice chromosome 1 encodes a NAC-domain transcription factor with DNA-binding and transcription activator activity. In rice, OsNAC6 is associated with defense response, blast disease resistance, salt and dehydration tolerance, growth, development, and yield. It is linked to regulation of root hair elongation, leaf senescence, stomatal closure, abscisic acid anabolism, and carbohydrate, amino acid, and lipid transport. The gene is also associated with heat and cold tolerance, grain filling period, net photosynthetic rate, maturity time, and brassinosteroid content. Studies of related genes in other species link the family to drought tolerance, ABA sensitivity, thermomemory, and pathogen resistance.
