A maize defense module of ZmNAC41, ZmABC, and ZmCP is linked to jasmonic acid–associated responses and mediates resistance to southern corn rust caused by Puccinia polysora.
- Why it matters: Multigene resistance modules are common, but how their components are organized and regulated in maize defense against SCR is not well defined.
- What they did: After SCR infection, ZmNAC41 rapidly increased and directly activated ZmABC transcription; ZmABC interacted with ZmCP, while JA accumulation and JA biosynthetic/response genes rose. Silencing any one gene reduced JA-associated defense responses and compromised resistance.
- The result: Elite haplotypes carrying favorable alleles of ZmNAC41, ZmABC, and ZmCP were significantly associated with enhanced field resistance, providing breeding targets for improved SCR resistance.
