The potato leafhopper finally has a reference genome! 🧬
A major milestone from the lab is now publicly available: a chromosome-level reference genome for Empoasca fabae is now live on NCBI.
🔗 NCBI Assembly: ncbi.nlm.nih.gov/datasets/ge…
It is exciting to see years of work become a resource that the broader community can build upon. I am confident this genome will help advance research on one of North America's most important insect crop pests and contribute to the development of more sustainable plant protection strategies. 🌱
The science behind this resource is coming soon—hopefully! 🤞 Our revised manuscript is currently under review.
This achievement was made possible through the support of @RqradQc and @NSERC_CRSNG via the @LeafHopeCan project. Congratulations to everyone involved! 👏

Did you know that roughly 11 million people die each year from causes linked to poor diets, while antimicrobial resistance is responsible for about 1.14 million direct deaths annually?
Both are major global challenges and deserve attention. But these numbers make me wonder: how do we decide which problems receive the most visibility, funding, and urgency?
Some issues dominate headlines, research agendas, and policy discussions, while others that affect far more people remain largely in the background.
Is it because some threats are perceived as more immediate? More novel? More scientifically attractive? Or does it have something to do with who is affected and where they live?

🚨 Leafhoppers in the Arctic? You have to be joking. Well… we are not.
Excited to share our latest publication, the first baseline assessment of leafhopper diversity across Nunavik and Nunatsiavut. Using specimens collected through the Nunavik Sentinels community science network, we documented 25 species, including 14 new records for Québec and Labrador.
This is only the beginning. We are now expanding this work in cloudberry patches to better understand insect diversity, microbiomes, and potential plant pathogens in a warming Arctic.
Bravo to Abraao and Nicolas for leading this work! 👏
This work was only possible thanks to the @LeafHopeCan project with @NSERC_CRSNG & @RqradQc support 👏

The agricultural pests known as plant bugs can be a farmer’s worst enemy. These winged insects—the size of a pea or smaller—suck the sap from apples, lettuce, and other crops, causing millions of dollars in damages globally each year.
A Costa Rican flower has turned this foe into friend, however, according to a 2022 study. One species of the so-called arum plant has evolved to attract a species of plant bug instead of a typical beetle pollinator, helping them spread their pollen far and wide.

Whether apoplastic small RNAs regulate plant immunity? Check our work in tomato identified their roles in priming plant defence to Phytophthora. Thanks for the wonderful suggestion from @wenboEffector and the professional processing of the editors at MP

My lab at @Stanford is looking to hire postdocs for multiple projects on cancer biology and therapeutics. Our recent work has uncovered some truly remarkable mechanisms for cytotoxic small molecules and we're looking to build on this research. If interested, see below:

Excited to share our new study in Microbial Genomics! 🎉
We provide evidence that ‘Candidatus Phytoplasma pruni’ has lost a functional GroE chaperonin system, offering new insights into genome reduction and evolution in phytoplasmas.
Thanks to @DumonceauxTim, @Edel_PLopez

Happy to see this collaboration led by @DumonceauxTim , with key contributions from @TPellegrinetti during his time in the lab! 🎉
What makes this study especially exciting for me is that Tim and I first started discussing the hypothesis that ‘Candidatus Phytoplasma pruni’ lacked cpn60 (GroEL) back in 2016, while we were developing diagnostic tools based on this molecular marker. At the time, it was an intriguing observation, but the available genomes were too fragmented to provide a definitive answer.
Almost a decade later, thanks to new high-quality genome assemblies, comparative genomics, and extensive work, we now have compelling evidence that this phytoplasma lineage has indeed lost a functional GroE chaperonin system. This work provides fascinating insights into genome reduction, gene loss, and the evolutionary trajectories of phytoplasmas.
Congratulations to everyone involved! 👏🧬🌱
