Characterization and silencing of differentially abundant proteins from Pyrenophora tritici-repentisDownload
Tan spot, caused by Pyrenophora tritici-repentis, is an important foliar disease of wheat. Three genes (stp, unp and glu) encoding proteins previously found to be more abundant in pathogenic versus non-pathogenic fungal isolates were cloned, characterized, heterologously expressed, and silenced...
Genetic structure, virulence and fungicide sensitivity of Pyrenophora teres f. teres and P. teres f. maculata populations from western CanadaDownload
The fungi Pyrenophora teres f. teres (Ptt) and P. teres f. maculata (Ptm) cause net form net blotch (NFNB) and spot form net blotch (SFNB) of barley, respectively. The genetic structure of a collection of 128 Ptt and 92 Ptm isolates, representing fungal populations from western Canada, was...
Local Mobile Gene Pools Rapidly Cross Species Boundaries To Create Endemicity within Global Vibrio cholerae PopulationsDownload
Vibrio cholerae represents both an environmental pathogen and a widely distributed microbial species comprised of closely related strains occurring in the tropical to temperate coastal ocean across the globe (Colwell RR, Science 274:2025–2031, 1996; Griffith DC, Kelly-Hope LA, Miller MA, Am. J....
Morphological characterization of fungi associated with the ascochyta blight complex and pathogenic variability of Mycosphaerella pinodes on field pea crops in central AlbertaDownload
Field pea crops in central Alberta were surveyed for ascochyta blight from 2011 to 2012 and fungal isolates were recovered from foliar lesions on selected plants. Cultural and microscopic characterization of the 275 isolates obtained revealed that 272 were of Mycosphaerella pinodes and three were...
The evolution of the myxoma virus in Australia has been presented for many years as a test case for the hypothesis that group selection can function effectively ‘in the wild.’ This paper critically examines the myxoma case, and argues that its failure as a test case for this hypothesis has...
