Control of Maize Sheath Blight and Elicit Induced Systemic Resistance Using Paenibacillus polymyxa Strain SF05.

ABSTRACT: Maize (Zea mays L.) is an important crop in the world and maize sheath blight damages the yield and quality greatly. In this study, an antagonist strain, which exhibited antagonism against pathogenic fungi of maize and controlled maize banded leaf sheath blight in the field, was effectively isolated and named Paenibacillus polymyxa strain SF05. High cellulase and chitinase activity of the strain were detected in this study, which might contribute to degrading the cell wall of fungi. Furthermore, different resistant genes such as ZmPR1a, OPR1 and OPR7 were elicited differently by the strain in the leaves and stems of maize. In order to explain the biocontrol mechanism of P. polymyxa strain SF05, the genome was sequenced and then the genes involving
