Zur is a regulator of the high-affinity @entity219 uptake system in many bacteria. In @entity68145 , a putative protein encoded by the open reading frame designated as XC1430 shows 42% @entity535 similarity with the Zur of @entity526 . An XC1430-disrupted mutant 1430nk was constructed by homologous suicide plasmid integration. 1430nk failed to grow in rich medium supplemented with @entity8862 at a concentration of 400 microM and in nonrich medium supplemented with @entity8862 at a concentration of 110 microM, whereas the wild-type strain grew well in the same conditions. In rich medium with 400 microM @entity8862 , 1430nk accumulated significantly more @entity8862 than the wild-type strain. 1430nk showed a reduction in virulence on the host plant Chinese radish (Raphanus sativus L. var. radiculus Pers.) and produced less @entity16290 ( @entity16290 ) than did the wild-type strain in the absence of added @entity219 . These results revealed that XC1430 is a functional member of the Zur regulator family that controls @entity219 homeostasis, @entity16290 production, and virulence in @entity17847 pv. campestris.

The @entity219 uptake regulator Zur is essential for the full virulence of XXXX pv. campestris.
