We recently showed that the wheat pathogen Stagonospora nodorum produces proteinaceous host-selective toxins (HSTs). These toxins include SnTox1 as well as SnToxA, a HST first identified from Pyrenophora tritici-repentis that was implicated in a very recent horizontal gene transfer event from S. nodorum to P. tritici-repentis. Compelling evidence implicating SnToxA and SnTox1 in disease develop...

Perennial weeds, including Cirsium arvense and Sonchus arvensis, are a common problem in crop fields, especially in agricultural systems with reduced herbicide usage. Herbicides recommended for control of these perennials generally are restricted to only a few active ingredients that tend to have low selectivity, especially on dicot crops. Microbial phytotoxins or their synthetic analogues may ...
