Inhibition of photosynthesis and modification of the wheat leaf proteome by Ptr ToxB: A host‐specific toxin from the fungal pathogen Pyrenophora tritici‐repentis
Tan spot, caused by Pyrenophora tritici‐repentis, is an important foliar disease of wheat. The fungus produces the host‐specific, chlorosis‐inducing toxin Ptr ToxB. To better understand toxin action,Expand
