Isolation and characterization of mitochondrial DNA of the oomycetous fungus Phytophthora infestans
SummaryMitochondrial DNA (mtDNA) of Phytophthora infestans has been isolated and preliminarily characterized. It has a low GC content of about 22.4% which is distinctly different from that of nuclearExpand

Restriction Fragment Length Polymorphisms of Mitochondrial DNA Among Phytophthora capsici Isolates from Pepper (Capsicum annuum)
Summary Seventeen isolates of Phytophthora capsici Leonian from various pepper-growing countries of the world were examined for restriction fragment length polymorphism (RFLP) of mitochondrial DNA.Expand

Amber mutants of Salmonella-phage P22 in genes engaged in the establishment of lysogeny
SummaryPhage mutants were isolated with amber mutations in genes necessary for establishment of lysogeny. These mutants form turbid plaques on su+ strain 527R1 and clear plaques of different types onExpand

Ribosomal DNA Restriction Fragment Analysis as a Taxonomic Tool in Separating Physiologically Similar Basidiomycetous Yeasts
Summary The taxonomic potential of restriction fragment analysis of the basic unit of the tandemly repeated ribosomal RNA genes was investigated. Four related basidiomycetous yeasts, CryptococcusExpand

The TRP1 gene of Phytophthora parasitica encoding indole-3-glycerolphosphate synthase-N-(5'-phosphoribosyl)anthranilate isomerase: structure and evolutionary distance from homologous fungal genes.
The TRP1 gene was isolated from the genome of Phytophthora parasitica. It encodes bifunctional enzyme of the tryptophan biosynthetic pathway indole-3-glycerolphosphateExpand

P22 antirepressor protein prevents in vivo recA-dependent proteolysis of P22 repressor
SummaryA method was developed to demonstrate recA-dependent P22-repressor breakdown in vivo by SDS-polyacrylamide electrophoresis of unfractionated extracts of phage-infected, lysogenic SalmonellaExpand

An amber map of Salmonella phage P22
SummaryForty five amber mutants of Salmonella phage P22 were assigned to 12 complementation groups. Two amber mutants could not be classified into any one particular group.Ten of the complementationExpand
