The newly assembled planthopper-Bartonellaceae genomes range in size from <2 Mb to 158 kb. The one most reduced lacks any essential amino acid biosynthesis genes, contrasting with all other insect-associated bacteria with ultra-reduced genomes, or other genes with obvious importance to hosts! 2/2

New preprint from our lab! We show that #Bartonellaceae bacteria, mostly known as mammalian #pathogens, also colonizes #planthoppers. The planthopper #symbionts typically resemble related ant symbionts in nutritional functions, but show a much greater breadth of #genome sizes and functions. 1/2

Highlights:
• Molecular records for Entomophthora’s new host clades from an unexplored bioregion - Greenland
• Confirmed high host-specificity of the pathogens;
• Provided the first records of bacteria seemingly associating with pathogen-killed flies;
• Validated multi-target sequencing approach

A new paper by our team @ioes-ju.bsky.social just published in J Invert Pathol @jinvertpathol.bsky.social!
In Diptera-#Entomophthora system, we show how simultaneously #sequencing #insect, #fungal #pathogen, and bacterial marker genes can aid biodiversity and biological interaction discovery.

New preprint by our team @ioes-ju.bsky.social! Using custom multi-target amplicon sequencing on diverse pathogen-killed dipterans from Greenland, we find multiple #Entomophthora genotypes with notable host specificity, and reconstruct bacterial communities associated with the killed insects.

I'm new to BlueSky - it's fun exploring this new site!
And here is a photo of me at another site that was new to me this year: collecting insects for microbiome research in Ilulissat, #Greenland. It's turned out great.
