Gene Details:

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. Furthermore, the generated data may be relevant for clarifying the functions of plant APXs.
  • Overexpression of Zea mays ascorbate peroxidase 1 (ZmAPX1) confers resistance against southern corn leaf blight.
  • These results suggest that ZmAPX1 decreases the accumulation of H2O2. In addition, we measured H2O2 contents in B. maydis-infected Mo17 and B73 plants, finding that the Mo17 plants accumulated lower H2O2 levels than B73 plants.
  • Taken together, these results suggest that the enhanced resistance against SCLB conferred by ZmAPX1 might be mediated by JA signaling.
