Gene Details:

• Gene ID: Zm00001eb013080
• Gene Symbol: ZmAPX1 ZmAPx01 ZmAPX1.1 apx3
• Gene Name: ascorbate peroxidase homolog3
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• These proteins included an ascorbate peroxidase (Zea mays ascorbate peroxidase 1 (ZmAPX1)) encoded by a gene located within the mapping interval of a previously identified quantitative trait locus associated with SCLB resistance.
• ZmAPX1 overexpression resulted in lower H2O2 accumulation and enhanced resistance against B. maydis. Jasmonic acid (JA) contents and transcript levels for JA biosynthesis and responsive genes increased in ZmAPX1-overexpressing plants infected with B. maydis, whereas ZmAPX1 mutants showed the opposite effects.
• These results demonstrate that ZmAPX1 positively regulates SCLB resistance by decreasing H2O2 accumulation and activating the JA-mediated defense signaling pathway. This study identified ZmAPX1 as a potentially useful gene for increasing SCLB resistance.
