Xanthomonas oryzae pv. oryzae Inoculation and Growth Rate on Rice by Leaf Clipping Method

Abstract

Bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious bacterial diseases and a major impediment to the increase of rice yield. Appropriate methods for inoculation of Xoo and disease scoring are necessary to investigate the nature of the disease and the mechanism of plant resistance to the pathogen. As the most-widely grown crop in the worldwide, rice yield plays an important role in food security. Uncovering mechanisms of plant-pathogen interaction of rice and Xoo will help develop rice plants that are more resistant to disease caused by Xoo. Here we describe our validated and efficient methods for inoculation of Xoo and disease scoring.
