Host Range Specificity in Verticillium dahliae.
TLDR
The results suggest that management of Verticillium wilt in some crops through crop rotation is a distinct possibility and host specificity exists in some isolates of V. dahliae. Expand
Phytophthora sojae races in Ohio over a 10-year interval
During 1978 and 1980, 199 isolates of Phytophthora sojae were obtained from soil samples from 16 fields in northwest Ohio using a soybean leaf disk bait procedure, and 53 isolates were obtained fromExpand
Characterization of Verticillium dahliae Isolates and Wilt Epidemics of Pepper.
TLDR
In general, incidence of wilt in jalapeno and bell pepper crops was lower than in crops of other types of pepper, and Pepper isolates belonging to VCG 2, VCG 4, and VCG 6 were highly pathogenic to bell pepper and chili pepper. Expand
Comparison of Media for Recovery of Verticillium dahliae from Soil.
TLDR
The medium developed in this study can serve as a direct replacement for the original NP-10 that was developed nearly three decades ago, an important component of which is no longer available. Expand
Mutations in VMK1, a mitogen-activated protein kinase gene, affect microsclerotia formation and pathogenicity in Verticillium dahliae
TLDR
Disruption of VMK1 via Agrobacterium tumefaciens-mediated transformation, in two V. dahliae isolates resulted in severely reduced virulence in diverse host plants, suggesting that VMK 1 is essential for pathogenicity and that the MAP kinase-mediated signaling pathway has a conserved role in fungal pathogenivity.

Genetic and physical mapping of Avr1a in Phytophthora sojae.
TLDR
This work provides a basis for the positional cloning of Avr1a, a locus in F(2) populations derived from four different P. sojae races that is controlled by host resistance (Rps) genes and pathogen avirulence (Avr) genes. Expand
A rapid infection assay for Armillaria and real-time PCR quantitation of the fungal biomass in planta.
TLDR
A new infection assay is tested, in which grape rootstocks growing in tissue culture medium are inoculated, and compared to rootstocks previously characterized from the existing infection assay as tolerant (Freedom) or susceptible (3309C); findings of higher percent root colonization than Freedom at all harvests suggests that the quantitative methods of the new assay give similar results to the qualitative method of theexisting infection assay.

Thermodynamics of monosaccharide binding to concanavalin A, pea (Pisum sativum) lectin, and lentil (Lens culinaris) lectin.
TLDR
Differential scanning calorimetry measurements on the thermal denaturation of the lectins and their carbohydrate complexes show that the Con A tetramer dissociates into monomers, while the pea and lentil lectin dimers dissociate into two submonomer fragments. Expand
The avocado subgroup of Phytophthora citricola constitutes a distinct species, Phytophthora mengei sp. nov.
TLDR
This new taxon is homothallic, produces plerotic oospores with paragynous antheridia and noncaducous semipapillate sporangia and can be easily differentiated from its relatives in the same clade and other species of this morpho-group by DNA fingerprints and sequence analysis. Expand
