Cool work on trypanosomatid Angomonas deanei by @MauryaAnay - the host has a neofunctionalised #dynamin-like protein ETP9 which localises to division site of bacterial #endosymbiont & is needed to maintain correct #symbiont inheritance during sync'd cell division #EESSymbiosis

How does Angomonas control the number of its bacterial endosymbionts? New paper from our lab finally out! Great team effort, guys! #endosymbiont #protist #evolution https://www.sciencedirect.com/science/article/pii/S0960982222017766?dgcid=author

#Wolbachia bacteria live inside #insect cells and transmit from mom to offspring. Some have adapted to kill male insects. This paper from #PNASNexus uses #CellCulture to determine that Wolbachia kill males by impacting the expression of #SexDetermination #genes in #moths.

#Advent Day14: #Drosophila hydei was originally a South American #Cactus specialist, but is now a global commensal https://www.sciencedirect.com/science/article/pii/S1055790312001789 and is the UK’s only common repleta-group fly. It has been studied as a host to parasitic mites https://doi.org/10.1017/s0031182016000305 and for a fascinating interaction between #Parasitoid wasps and defensive #Endosymbiont Spiroplasma https://doi.org/10.1371/journal.pone.0012149 . It also briefly held the crown for the longest drosophilid sperm, at around 10 body-lengths https://www.pnas.org/doi/abs/10.1073/pnas.91.20.9277

#Wolbachia #endosymbiont #bacteria sometimes cause #MaleKilling.

In this paper from @naturecomms, researchers identify a gene called Oscar which kills males by targeting the host Masculinizer protein in #butterflies. Oscar has #ankyrin repeats and a #ulp1 domain similar to the male killing gene #Spaid in #Spiroplasma.

wAlbB #Wolbachia #endosymbiont #bacteria are used to control #Aedes #mosquito transmission of #dengue.

Here, authors perform comparative #genomics of two wAlbB. Repeat elements significantly contribute to variations in the genomes, especially around the #phages.

These differences contribute #temperature resistance. The resistant strain is a good candidate for future release efforts!

#Endosymbiont #Wolbachia #Bacteria prevent ovary development in #Aedes #mosquitoes. Pretty unusual since Wolbachia are maternally transmitted. This has a huge impact on #insect fitness.

"Wolbachia inhibits ovarian formation and increases blood feeding rate in female Aedes aegypti"
