The Pseudomonas-Plant Interaction Project originated with a proposal by a group of investigators, headed by Dr. Alan Collmer at Cornell University, to determine the genome sequence of P. syringae pv tomato DC3000 and begin exploration of the functional genomics of its interaction with the host plant tomato. Funding was provided by the NSF Plant Genome Research Program grant DBI-0077622 and the sequencing was performed at The Institute for Genome Research (TIGR). Cost savings from the DC3000 sequencing project are presently being used by TIGR to complete genome sequencing and annotation for P. syringae pv. phaseolicola 1448A.

Rationale for obtaining a complete sequence of a second P. syringae strain:

  • a roadmap to pathogenicity islands and other fitness islands
  • a reference for global interpretation of the Pto DC3000 genome
  • a reference for studying the evolution of virulence
