Physiology of Batrachochytrium dendrobatidis, a chytrid pathogen of amphibians.
The zoospore activity, physiology and protease production of B. dendrobatidis is investigated to help understand the epidemiology of this pathogen, which is implicated in severe population declines on several continents. Expand

A sensitive and specific polymerase chain reaction–based assay to detect this pathogen B. dendrobatidis from captive and wild amphibians collected across North America and sequenced the internal transcribed spacer regions of the rDNA cassette of multiple isolates. Expand
Recent advances in the molecular genetics of plant cell wall-degrading enzymes produced by plant pathogenic fungi
A new approach using recombinant DNA techniques has been employed to try to provide more conclusive evidence concerning the role of CWDE in plant pathogenesis. Expand
Infection and colonization of peanut pods by Aspergillus parasiticus and the expression of the aflatoxin biosynthetic gene, nor-1, in infection hyphae.
A histological study of the host–pathogen interaction between peanut, Arachis hyphogea, and A. parasiticus was performed in a system where peanuts remained attached to the plant and were inoculated without wounding. Expand
Fungicide Sensitivity Assessed in Monilinia vaccinii-corymbosi Isolates from Lowbush Blueberry Fields in Maine
The biennial long-term use of the fungicide propiconazole on populations of M. vaccinii-corymbosi may contribute to the development of fungicide insensitivity over time, and the use of fenbuconazole has become more widely used in the last 4 years than previously. Expand
Rapid identification of genetic variation and pathotype of Leptosphaeria maculans by random amplified polymorphic DNA assay
Canadian isolates of Leptosphaeria maculans, the causal agent of blackleg of crucifers, were examined for genetic relatedness by the random amplified polymorphic DNA assay and results agreed with other reports which showed many genetic differences between pathotypes. Expand
Transposon-like sequences at the TOX2 locus of the plant-pathogenic fungus Cochliobolus carbonum.
The sequence similarity of the C. carbonum repetitive element to other fungal transposons, along with its presence in multiple copies per genome, strongly suggest that the C.'s carbonum genome may be active, and is a member of the Fot1 family of fungalTransposons. Expand
Using Peer Discussion Facilitated by Clicker Questions in an Informal Education Setting: Enhancing Farmer Learning of Science
The results suggest that clicker questions and peer discussion work equally well with adults from a variety of demographic backgrounds without disadvantaging a subset of the population and provide an important learning opportunity to the least formally educated members. Expand
Efficacy of Organically Acceptable Materials for Control of Mummy Berry Disease on Lowbush Blueberries in Maine
The efficacy of biological controls and application of mulch for control of the blight stage of mummy berry disease was examined in different lowbush blueberry fields in Maine over 5 years.… Expand
Pathotype identification of Leptosphaeria maculans with PCR and oligonucleotide primers from ribosomal internal transcribed spacer sequences
This PCR-based assay utilizing pathotype-specific primers was employed to detect an isolate of the highly virulent pathotype of L. maculans in infected plant tissue and shows promise as a diagnostic tool. Expand
