Congrats all!

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

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

We had an amazing time filled with inspiring discussions on Ophiocordyceps, symbiosis, and our collaborative research. Exciting plans ahead! @sympiotr.bsky.social

yes - you can add me to your Microbiology feed :)

Thanks Sean!

Also, we found unusual genomic changes in ancient nutritional endosymbionts Sulcia and Vidania. #Sulcia genome experienced multiple rearrangements and fragmentation. #Vidania lost many genes, resulting in the smallest stand-alone bacterial genome described so far - at 109 kb.

We showed that Acetobacteraceae symbionts can utilize Sulcia symbiont cells as vessels for transmission across host generations.
Acetobacteraceae symbiont’s genomic features suggest a unique combination of ability to horizontally transmit among species and confer nutritional benefits

Thanks Alejandro!
It's great to join this fantastic symbiosis community!
