Phytoplasma-specific PCR primers based on sequences of the 16S-23S rRNA spacer region.
In order to develop a diagnostic tool to identify phytoplasmas and classify them according to their phylogenetic group, we took advantage of the sequence diversity of the 16S-23S intergenic spacerExpand

Genetic Change Within Populations of Phytophthora infestans in the United States and Canada During 1994 to 1996: Role of Migration and Recombination.
ABSTRACT Dramatic changes occurred within populations of Phytophthora infestans in the United States and Canada from 1994 through 1996. Occurrence of the US-8 genotype, detected rarely during 1992Expand

The 2009 Late Blight Pandemic in the Eastern United States - Causes and Results.
The tomato late blight pandemic of 2009 made late blight into a household term in much of the eastern United States. Many home gardeners and many organic producers lost most if not all of theirExpand

cDNA cloning and molecular characterization of cherry green ring mottle virus.
The complete nucleotide sequence of the cherry green ring mottle virus (CGRMV) genome was determined to be 8372 nt excluding a 3' poly(A) tail. Based on computer analysis and sequence comparison,Expand

Implications of Sexual Reproduction for Phytophthora infestans in the United States: Generation of an Aggressive Lineage.
Phytophthora infestans isolates (n = 26) collected in the Columbia Basin of Oregon and Washington in 1993, which had been characterized previously for mating type, metalaxyl sensitivity, and allelesExpand

Gene profiling of a compatible interaction between Phytophthora infestans and Solanum tuberosum suggests a role for carbonic anhydrase.
Late blight of potato, caused by the oomycete pathogen Phytophthora infestans, is a devastating disease that can cause the rapid death of plants. To investigate the molecular basis of this compatibleExpand

rep-PCR-Mediated Genomic Fingerprinting: A Rapid and Effective Method to Identify Clavibacter michiganensis.
ABSTRACT The genomic DNA fingerprinting technique known as repetitive-sequence-based polymerase chain reaction (rep-PCR) was evaluated as a tool to differentiate subspecies of ClavibacterExpand

Genetic mapping from field tests of qualitative and quantitative resistance to Phytophthora infestans in a population derived from Solanum tuberosum and Solanum berthaultii
Under controlled field conditions, a Solanum backcross population segregated for resistance to Phytophthora infestans. The population (`BCT') had been derived previously by crossing the SolanumExpand

The phytoplasma associated with ash yellows and lilac witches'-broom: 'Candidatus phytoplasma fraxini'.
Phytoplasmas associated with the plant diseases ash yellows (AshY, occurring in Fraxinus) and lilac witches'-broom (LWB, occurring in Syringa) represent a putative species-level taxon. PhytoplasmalExpand
