Upcoming Webinar: Using High-Throughput Methods to Explore Pathogen Adaptation Tactics

When environmental conditions shape disease outbreaks, abrupt or frequent changes in climatic patterns might alter disease trajectories, as well as their implications for the host–pathogen arms race. Join this installment of the Bacteriology Series to discover recent findings on the adaptation strategies of endemic pathogens adjusting to environmental variations and to the agricultural settings on seasonal timescales.  ​

​​First Reported Sexual Recombination Between Pyrenophora teres Isolates from Barley and Barley Grass

Barley grass (Hordeum leporinum), which often occurs in proximity to commercial barley (H. vulgare) cultivars, is an alternative host to Pyrenophora teres, an economically important pathogen causing net blotch in barley. This study is the first to report the sexual recombination of P. teres isolates collected from barley with those collected from barley grass.
