Response of an aspartic protease gene OsAP77 to fungal, bacterial and viral infections in rice.

ABSTRACT:

Background

Aspartic protease (APs) plays important roles in plant growth, development and biotic and abiotic stresses. We previously reported that the expression of a rice AP gene (OsAP77, Os10g0537800) was induced by probenazole (PBZ), a chemical inducer of disease resistance. In this study we examined some characteristics of this gene in response to fungal, bacterial and viral pathogens.

Results

To elucidate the spatial and temporal expression of OsAP77, the chimeric gene was constructed carrying the structural gene encoding β-glucuronidase (GUS) driven by the OsAP77 promoter. This construct was introduced into rice and the transgenic lines were tested to analyze gene expression by fungal, bacterial and viral infections. Inoculation with Magnaporthe oryzae or Xanthomonas o
