Isolation And Identification Of A Novel Ginger Tissue Pathogenic Bacteria Citrobacter Sp. Sj7

The pathogenic bacteria of ginger plantlets were isolated and identified. Pathogenic strains were isolated, purified, and then identify by morphology observation, physiological and biochemical experiments, and the 16s rDNA sequence was analyzed to verify the classification of the pahtogen. This study shows the novel pathogenic bacteria is kind of Gram-negative ones, which can be well root on the ginger tissue as well as cultivated plantlets. The histopathology examination illustrates that the pathogen prefer infect the host plant through ginger tuber. Moreover, the16S rDNA sequence analysis exhibits that it is kind homology species closely relating to Citrobacter amalonaticus. In a word, we first isolated a novel pathogenic bacteria of ginger named as Citrobacter sp SJ strain, which could successfully recognize the host ginger via xylems.
