First large-scale breakdown of Yr15 resistance to #wheat yellow #rust (Puccinia striiformis f. sp. tritici) recorded globally doi.org/10.1002/ndr2.7…

@CeResLab_IAS @Gracia_Montilla @IAS_CSIC @UPLublin Nice settling towers! Is it for mildew inoculation?

Always a pleasure to connect with our collaborators! 🌱✨ Our colleague @Gracia_Montilla is now at the Life Science University of Lublin with Prof. Edyta Paczos-Grzęda’s group — moments that open new paths for future projects. @IAS_CSIC @UPLublin

VERY HAPPY to share our last publication in @GenomeBiology ...In a world full of SNPs...k-mers made the most biological sense out of the complex wheat genome! 🌱🧬 genomebiology.biomedcentral.com/articles/10.11… Grateful to Benji (@benjamin_jaegle ) for the trust, & co-authors for their collaboration!

Our @theccdm @InterGrain1 @tony_ancy poster on wheat powdery mildew pathotyping is up! Come and chat with us on Wednesday! 🙏😀 #ICRPMC2025 @17thICRPMC

The longest #StemRust pustule on tallest cereal in the field. Spotted on #rye @MGIHUNREN in Martonvásár, Hungary

@wheatpath Nice phenotypes! If rust can accomplish it's infectious cycle on there hosts. Do you still classify infection types 1 to 4 as resistant/nonhost?

Two weeks later, numerous Puccinia graminis pustules appeared on grasses, each with a distinct appearance. This required the development of a qualitative scoring scale to distinguish between host interactions (susceptibility) and non-host interactions(resistance).

📢 Abstract submission extended! New deadline for the 23rd International #Bunt & #Smut #Workshop is March 17, 2025! 🗓️ Join us in #Uppsala (June 1-2) to discuss the latest research on bunt & smut diseases. 🌱🔬 🔗 More info: 2025buntworkshop.wordpress.com

@gurcharn_brar @CBL_UA @globalrust Is it mildew on flag leaf? Surprised to see such severity of powdery mildew on these Pm38 lines

These type of lines carrying Lr34/Yr18 usually have a yield penalty, so I normally cull these lines. Look at how pronounced leaf tip necrosis (LTN) is.

Save the date! 🗓️ Thu 30 Jan 12pm AEST/2pm NZST Our January seminar will feature Rita Tam @ritahltam from @BiologyANU on the genomics of rust fungi! Free registration (donations welcome) australasianmycologicalsociety.com/virtual-semina…… @EcolSocAus @ausplantsoil @Plant_Pathogens

From lesions to lessons:  2025 marks the 20th anniversary of filamentous plant pathogen genomics. In our new review, we present lessons we learned over the past 2 decades and discuss the future of plant pathogen genomics. Take a first look! apsjournals.apsnet.org/doi/epdf/10.10…

@liz_brauer What kind of toxin induced this necrosis?
