📢 EffectorGeneP is finally here! Stop missing small, single-exon or orphan genes from your favourite pathogen genome. Current tools only annotate 15%-78% of effector genes, EffectorGeneP finds 95% - including the large AvrSr26 family in stem rust. #Bioinformatics 📖 www.biorxiv.org/content/10.6...

"The order of fungal infection can influence disease severity and plant resistance" Our @theccdm.bsky.social paper on fungal co-infection of wheat is out @PlantDiseaseJ. Collab @agtbreeding @DPIRDbroadacre @evan-john.bsky.social. Link below @theGRDC Groundcover.
Centre for Crop and Disease Management@theccdm.bsky.social · 4mo ago🔬 New insights from CCDM reveal infection order matters. When yellow leaf spot (YLS) infects first, it primes wheat for septoria nodorum blotch (SNB) — but when SNB strikes first, it suppresses YLS. 🔗 Read here: groundcover.grdc.com.au/grdc/announc... @curtinuniversity.bsky.social, #GRDC

Our @theccdm.bsky.social preprint on the domain function and interactors of the effector-regulating transcription factor PnPf2 in Parastagonospora nodorum is live! 😁 Led by Shota Morikawa @callumverdonk.bsky.social Collabs 👉 @danielcroll.bsky.social @evan-john.bsky.social
A conserved fungal transcription factor domain drives protein-protein interactions and necrotrophic effector-mediated virulence in Parastagonospora nodorum
The fungal pathogen Parastagonospora nodorum utilises necrotrophic effectors (NEs) to cause chlorosis and necrosis on wheat. NE expression is mediated by an assortment of transcription factors (TF), t...

Where to start, with a statement like this? "Tim Ayres said the cuts were aimed at refocusing … CSIRO towards research priorities, such as critical minerals, iron & steel production in Australia." From some rando down the bus stop, one would brush it off. But this is from our Science Minister 🤯
CSIRO to cut up to 350 research jobs in major overhaul
After 440 positions were slashed last year, the CSIRO has announced more staff cuts across the country in a bid to remain financially viable.

Do we need to reassess how disease resistance ratings on crops are determined? 🤔 Our @theccdm.bsky.social preprint revealed co-infection of wheat by P. nodorum & P. tritici-repentis breaks down resistance BUT there is a CAVEAT www.biorxiv.org/content/10.1...
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...

Excited to see the final version of our paper on toxin/antidote genes and accessory chromosomes in Fusarium published! Now with new and improved figures! We think that many #fungal ACs might be maintained not because of benefits to virulence, but because of Spok genes. doi.org/10.1093/gene...

Pathogenic fungus exploits the lateral root regulators to induce pluripotency in maize shoots
Biotrophic plant pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all ...
