Western Alaska was hit hard by the recent storms. Houses floated away in Kipnuk, houses flipped over, people lost everything from the flooding that came with the storms. Please donate if you can. This group has a long history of supporting AK communities.

Population-Specific Transcriptomic Shifts Underlie Secondary Metabolic Diversification in Aspergillus flavus and the Domestication of Aspergillus oryzae https://www.biorxiv.org/content/10.1101/2025.10.02.680074v1

Yes! It's an interesting species complex with lots more still to discover. We were surprised several times by the results of this project!

I was only part of this project, not the lead--it was actually led by my postdoc advisor Mickey Drott & our collaborator Denny Wang, who are not #OnHere. Other collaborators who ARE on here include @rokaslab.bsky.social @kellerlab.bsky.social & @gibbonsgenomics.bsky.social
Stay tuned for more!

Using isolates from both species, we saw population-specific transcriptomic differences due to a few transcription factors (notably missing pop. D isolates, as this was an earlier experiment).
Basically, it seems domestication was made possible through regulatory changes rather than genetic ones!

We also tested virulence in a zebrafish model. All the isolates were capable of causing disease, BUT isolates from population A were the most deadly.

The A. oryzae isolates were the *least* virulent, which is very good news for culinary enthusiasts.

We found evidence for multiple domestication events for A. oryzae (blue clades O1 and O2), & we saw that the A. oryzae isolates were interspersed in the newly defined population D, which has a LOT of clinical isolates--pretty weird and unexpected! 👀

If you saw my talk on the population structure of #Aspergillus flavus at Fungal Genetics in 2024, you might have heard someone ask "how does Aspergillus oryzae fit into the picture?"
If so, you heard my answer was "wait and see--we're working on this exact topic"
Well, the wait is over! Preprint ⬇️

Convergent evolution of aerobic fermentation through divergent mechanisms acting on key shared glycolytic genes As the tree of life becomes increasingly accessible to molecular investigations, describing mechanisms underlying evolutionary convergence and constraint will be crucial to understanding diversificati...

What started as a project characterizing variation in metabolic rates across yeasts turned into an interesting story about convergent evolution acting on the same key genes through distinct molecular mechanisms with @hittingerlab.bsky.social & @rokaslab.bsky.social.

If you are a current PRFB fellow, we have a slack where all of this and more is discussed.

Current fellows, please send me a message and I can add you.

USDA funding delays under Trump compromise agricultural research Sharp drop in grant awards leaves researchers frustrated

"With 2 weeks left before the end of this fiscal year, USDA’s [NIFA] had awarded just 558 competitive grants ... 68% fewer than during the prior fiscal year—and $741 million less in competitively awarded research funds"

Don't forget #PlantSci and ag research, folks.
