- Nitrogen fertilization increases rice susceptibility to blast (Nitrogen-Induced Susceptibility, NIS).
- GWAS on 268 rice accessions identified loci like NIS4 on chromosome 8 with F-box protein genes.
- Negative NIS (resistance under high nitrogen) correlates with rapid defense via peroxidase and lignin.
- Susceptible lines show delayed defense; active nitrogen assimilation (GS/GOGAT) is linked to susceptibility.
- Polymorphism in NIS has a genetic basis involving nitrogen redirection for early defense activation.
