Transcriptome of Pseudomonas putida KT2440 under zinc stress

Pseudomonas putida is a ubiquitous saprophytic bacterium with a remarkable adaptability to diverse environments. Although the genomic sequence data deposited in Genbank allow for the listing of putative gene involved in zinc homeostasis, they do not provide functional evidence. In order to get insights into the does-dependent transcriptional responses of P. putida to external zinc, transcriptomes of P. putida KT2440 were sequenced. The results revealed that different sets of genes were activated or repressed in response to elevated levels of zinc ions, which provides an in-depth understanding of the adaptation mechanisms used by P. putida to survive in Zn-polluted environments.
