SbNAC functional evidence in sorghum is concentrated in a few NAC genes, including SbNAC2 linked to SbAP37 activation and SbNAC9 altering drought traits.
- Why it matters: Drought, salinity, and temperature extremes limit sorghum productivity, yet SbNAC gene counts and stress-linked expression patterns vary across studies, leaving mechanisms uncertain.
- What they did: The review synthesizes genome-wide SbNAC characterization, transcriptomic responses to drought, salinity, cold, and abscisic acid, and functional studies plus multi-omics and network analyses.
- The result: It distinguishes candidate pathways from experimentally supported SbNAC-mediated regulation, prioritizing validation of SbNAC roles for sorghum stress adaptation and crop improvement.
