Restriction Fragment Analysis

We used restriction fragment analysis of chloroplast, nuclear, and mitochondrial DNA to study phylogeny in the genus Pseudotsuga. Total genomic DNA from one outgroup (Larix occidentalis Nutt.) and five Pseudotsuga species from Japan, mainland China, Taiwan, and North America were digested with 20 restriction enzymes, blotted, and probed up to 17 times with cloned DNA fragments. A total of 38 shared fragment characters were subjected to Wagner parsimony analysis coupled with bootstrapping to evaluate statistical significance of the phylogenetic trees. The complex patterns that we observed for actin gene fragments were evaluated via a Fitch–Margoliash distance-matrix analysis. Both parsimony and distance-matrix analyses indicated that relationships among species in the genus coincide with their current geographic distribution; genetic similarity declines with migration distance around the Pacific Rim. The Asian and North American species form well-differentiated and statistically significant monophyletic groups. Pseudotsuga japonica is the Asian species closest to the North American species. Affinities to the outgroup Larix occidentalis suggest that Pseudotsuga originated in North America and then migrated into Asia. Key words: parsimony, phylogeny, biogeography, conifer, Pinaceae.

Seventeen virulent bacteriophages specific to Pseudomonas aeruginosa strains were isolated by screening various environmental samples. These isolated bacteriophages were grouped based on results obtained from restriction fragment analysis of phage genomes, random amplification of polymorphic DNA (RAPD) typing, morphology observations under transmission electron microscope, and host range analysis. All 17 bacteriophages are double-stranded DNA viruses and can be divided into 5 groups based on DNA restriction profiles. A set of 10-mer primers was used in RAPD typing of phages, and similar conclusions were obtained as for restriction fragment analysis. One phage was randomly selected from each of the 5 groups for morphology observations. Four of them had an icosahedral head with a long contractile tail, belonging to the Myoviridae family, and one phage had an icosahedral head with a short tail, thereby belonging to the Podoviridae family. Host range experiments were conducted on 7 laboratory strains and 12 clinical strains of P. aeruginosa. The results showed that 13 phages had the same infection profile, killing 8 out of 19 tested P. aeruginosa strains, and the remaining 4 phages had different and unique infection profiles. This study highlights the diversity of bacteriophages specific to P. aeruginosa in the environment.
