📢 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...

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...

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...
Model for the maintenance of accessory chromosomes by FuSpoks. Triangles represent the toxin function of the proteins, and circles represent the antidote function. Core chromosomes are depicted in grey, with ACs in red. A) A dividing cell within a hyphal tip, expressing a SPOK protein from an AC. B) A dividing cell within a hyphal tip, expressing a SPOK protein from an AC. The AC is lost during mitotic division, resulting in a cell containing Spok toxin, but with no ability to produce Spok antidote. This cell is expected to die.
