Natural transformation is a mechanism for intra- and interspecific transfer of chromosomal DNA in Pseudomonas stutzeri. During this process a single strand derived from duplex DNA is transported into the cytoplasm and recombined with resident DNA. By electroporation, which introduces duplex DNA into cells, 100-fold lower transformation frequencies of P.(More)
Pseudomonas stutzeri, in addition to being transformed by duplex DNA, is also transformed by the sense or antisense strand of the genetic marker employed (hisX(+)) or by heat-denatured chromosomal DNA. Transformation was absent in non-competent cells and in mutants defective for pilus biogenesis (pilA, pilC) and function (pilT) or DNA translocation into the(More)
