Thrilled to share the final version of our manuscript! 🎉 @estukenbrock.bsky.social and I investigated the secretome of the barley pathogen #Zymoseptoria passerinii and asked what its protein structures could tell us about #effector evolution. 🔗 link.springer.com/article/10.1... 🧶👇🏻

Background During host colonization, fungal plant pathogens secrete effector-like proteins that alter host cell physiology and target plant-associated microbes. However, rapid evolution and low sequen...

New preprint online! We sequenced several hundred Zymoseptoria isolates from different fields through a field epidemic to ask what really drives short-term evolution. Fungicide selection or seasonal epidemic progression? www.biorxiv.org/content/10.6...

#Puccinia graminis f. sp. tritici threatens wheat production worldwide. Md Al Mamun et al. identified marker-trait associations that can potentially be used to transfer resistance loci to develop stem rust-resistant wheat varieties: doi.org/10.1094/PDIS-12-25-2561-RE
Fig. 1. Manhattan plots from genome-wide association studies showing the distinct peaks for identified marker-trait associations (MTAs) in response to A, TMLKC; B, LBBLC; C, HKHJC; and D, QFCSC races of Puccinia graminis f. sp. tritici. The green horizontal line represents the threshold used to report MTAs for each race.

#Rust on marsh grass of Parnassus (#Parnassia palustris) caused by #Puccinia uliginosa — a somewhat aged specimen (Estany de Vallell, Carlit massif, FR). Another rarity 🤩 found here at the southern edge of its European range, a reminder of the glacial legacy of the #Pyrénées.

#Rust on alpine marsh violet (#Viola palustris) caused by #Puccinia fergussonii (Estany de la Predella, Carlit massif, FR). A rarity 🤩— probably one of the southernmost occurrences in Europe — illustrating how the #Pyrénées harbour great biodiversity inherited from glacial past.

Estany de Sobirans, the last of the 12 lakes beneath #Carlit, the highest peak in the Pyrénées-Orientales (FR): an ideal setting to start searching for rare #rust fungi on endemic Pyrenean plant species!

#Eriophyes alpestrisi, the rhododendron gall mite, on #Rhododendron ferrugineum, causing the leaves to roll upwards along the midrib and disrupting flower development (Estany de la Predella, massif du Carlit, FR). At first, I thought it might be a rust. Little disappointment! 😅
