%X Acidovorax citrulli(Ac) is an important bacterium that occurs in watermelon,melon and other cucurbits.It mainly damages watermelon and melon,and can cause leaf blight,fruit rot,and even mortality.Objective] To verify the relationship between defects in the synthesis of histidine and the pathogenicity of Ac.Methods] We generated a transposon(Tn5) mutant library on the background of strain xjl12 of Ac.Then we used subclone technology to identify the gene.Results] The mutant could not elicit the hypersensit...
