[ pv. Zur is involved in pathogenicity in host and hypersensitive responses in nonhosts].

The zinc uptake regulator (Zur) has highly conserved sequences in the plant pathogen , while its functions are diverse in different strains or races. To elucidate the functions of Zur in pv. (), we constructed a -deleted mutant (Δ) by homologous recombination.

[The role of iron-uptake factor PiuB in pathogenicity of soybean pathogen pv. ].

Iron is an essential element for living organisms that plays critical roles in the process of bacterial growth and metabolism. However, it remains to be elucidated whether encoding iron-uptake factor is involved in iron uptake and pathogenicity of pv. ().
