Biocontrol of <i>Macrophomina phaseolina</i> (Tassi) Goid: differential production of H₂O₂ and in the relationship pathogen – PGPR in soybean seedling

Abstract

We examined the biocontrol and the differential production of H2O2 and in the relationship Macrophomina phaseolina – PGPR in soybean seedling. Fungal colonisation was efficiently prevented by inoculation with Pseudomonas fluorescens 9. Its ability to improve ROS production and gene expression of antioxidant enzymes could be related to its capacity to control the disease.
