摘要： Mung bean (Vigna radiate L.) is a major legume crop and widely planted in China. A new bacterial foliar disease similar to wildfire was observed on the mung bean plants. This study was conducted to determine the causal agent inducing wildfire-like symptoms on mung bean. The bacterial isolates obtained from mung bean were performed to detailed identification. All isolates showed the similar morphology and molecular characteristics to those of Pseudomonas syringae. By pathogenicity tests, the isolates were strongly pathogenic to mung bean and tobacco, a common host of wildfire disease. Based on the morphological and molecular characteristics, including the specific detection of toxin genes, rDNA sequences and a phylogenetic analysis, fatty acid composition, physiological and biochemical properties, all isolates were identified as P. syringae pv. tabaci. To the best of our knowledge, this is the first report of wildfire induced by P. syringae pv. tabaci on mung bean worldwide.
