xanthomonas translucens xanthomonas translucens xanthomonas translucens is a species of phytopathogenic bacteria. it is the causal agent of bacterial leaf streak in of wheat and cereal crop. the bacterium is transmitted as a seed-borne pathogen. the transmission rate is very low but ensures serious outbreaks in the field under suitable conditions. the pathogen is a non-sporing, aerobic, motile, gram-negative, rod bacterium with a single polar flagellum. xanthomonas translucens scientific classification domain: bacteria phylum: pseudomonadota class: gammaproteobacteria order: xanthomonadales family: xanthomonadaceae genus: xanthomonas species: x. translucens binomial name xanthomonas translucens(jones et al. 1917) vauterin et al. 1995 subspecies x. t. pv. translucens (syn. x. campestris pv. translucens) causes a bacterial leaf streak of wheat.: 113 xts medium is developed and presented in schaad & forster 1985.: 113 xts medium is semi-selective for xtt.: 113 although some problems with this agar are known, nothing better is available.: 113
