To wrap up…!
Why keep an effector the plant can recognize?
Our postdoc Liz Florez shows Z. tritici’s effector AvrStb6 shapes the wheat microbiome, esp. Pseudomonas spp., in susceptible cultivars. A hidden microbial modulation role beyond host recognition?

How does heat reshape plant immune responses?
Our PhD student Anica Schmauch shows higher temperatures boost ROS bursts in barley and potentially affect Z. passerinii growth, revealing abiotic-biotic cross-talk in disease resistance.

What makes wild wheat resistant to domestic Zymoseptoria?
Our PhD student Rune Hansen found wild wheat relatives that stop infection by domestic Zymoseptoria at the stomata, with a pool of candidate genes that could potentially boost resistance in domestic wheat.

The fungal effector AvrStb6 regulates the wheat pathobiome
Zymoseptoria tritici, the causal agent of the foliar disease Septoria tritici blotch (STB), is a major wheat pathogen in Europe. Although several wheat resistance (R) genes have been identified, Z. tr...

Can fungal pathogens manipulate the plant microbiome to aid infection?
PhD student Leonhard Pachinger shows Z. tritici expression of killer-like protein effectors KP-4 & KP-6 that inhibit apoplastic bacteria, suggesting a microbiome-targeting strategy during infection.

How does mowing and grazing shape the leaf and root microbiome of a wild grass?
Our PhD student Eva Tanneau tracked 3 years of Agrostis capillaris microbiomes and found striking shifts under different management regimes, including pathogen emergence in leaf networks.

Can fungal pathogens hijack host signaling peptides?
Our PhD student Maxim Faroux @molecularmax.bsky.social uncovers a Zymoseptoria KEX2-processed effector putatively mimicking the plant hormone peptide phytosulfokine (PSK) known to lower immunity against hemibiotrophs.
