Rice phyllospheric Pantoea spp. suppress blast and bacterial blight diseases.

ABSTRACT:

Background

Rice is a major food crop in China as well as Asia, yet its production is threatened by microbial diseases including blast disease caused by fungal pathogen (Magnaporthe oryzae) and bacterial blight caused by several bacterial pathogens. To screen for bacterial microbiota associated with rice blast occurrence, and/or contributing to disease resistance, we performed microbiota analysis with rhizosphere soil, root, stem, and leaf samples of blast susceptible (CO39) and resistant (Y33R) rice grown in a blast disease nursery garden.

Results

Our result showed no significant difference in microbiota of rhizosphere soil, root, or leaf between these two rice cultivars, but stem microbiota were significantly different. Pantoea spp. were enriched in stem of blast susceptibl
