Fair-weather friends: Unequal partnerships between Parastagonospora nodorum and Pyrenophora tritici-repentis define disease dynamics in wheat
Parastagonospora nodorum and Pyrenophora tritici-repentis are the causal agents of septoria nodorum blotch and tan spot of wheat, respectively. Though these fungal phytopathogens have been found to fr...

When yellow leaf spot (YLS) infects first, it primes wheat for septoria nodorum blotch (SNB) — but when SNB strikes first, it suppresses YLS.
