摘要: A genome analysis of Pseudomonas pseudoalcaligenes KF707, a PCBs degrader and metal-resistant soil microorganism, revealed the presence two novel gene clusters named che2 che3, which were predicted to be involved in chemotaxis-like pathways, addition che1 cluster. We herein report that histidine kinase coding genes, cheA2 cheA3, have no role swimming or chemotaxis P. contrast cheA1. However, cheA1 genes both necessary for cell swarming, whereas cheA3 product had negative effect on optimal swarming phenotype KF707 cells.
