Last chance to join us next month for the #Biodiversity25 conference.

A fantastic set of speakers, mix of talks & focused workshops, and the chance to meet others in the field of biodiversity genomics 🧬

In-person registration closes next Monday 29th September!

Aww. The thought generates happy feelings in the Liverpool symbiont community!

Well it is different, but was inspired by Margaret's paper. Symbionts were always going to be easier, as they often have active mechanisms for infecting the germ line.

John Jaenike did follow up for mites moving spiroplasma symbionts, which made the same shift (will group-》mel). It worked and he did get heritable transmission in recipient mel at a low rate. Which was very cool.

As an editor, I found them occasionally counter productive- a reviewer would write a thing (e.g fine but iterative) but not write this in the review - so as an editor made decisions harder to justify. Save misconduct, if you want it part of the review process, write it direct to authors.

Two fully funded #PhD positions on insect #Symbiosis available in our lab: Spiroplasma in Neotropical Arthropods (tinyurl.com/spiroplasma) & Psyllid symbionts (tinyurl.com/psyllids).

Rickettsia in the form of Ca Tisiphia is in amoebae and inverts. More widely, rickettsiales are everywhere really (inverts and lots of microeuks).

The Rickettsia is about double 'normal' size. In the plot below, blue lines are insertion sequences locations. Over half the genome. I still find it remarkable this bacterium is able to grow and replicate!

Did the chicken pox vaccination privately when F1 was 10 and hadn't caught it. It is pretty unpleasant as a disease in adults.... (I got it at 17 yeuch)

Symbiont genomes are generally small, losing content. However, mobile element proliferation occasionally drives genome expansion. Is this a chance thing? Emily observed coinfecting symbionts with greatly enlarged genomes (via distinct mobile elements) implying an underlying driver of expansion. 2/2

Our New Paper is out! Great work by Mashaneh Ahrar and the team - thank you all, especially @makaefer.bsky.social and Greg Hurst (is he on Bsky???)! TBC :)

Please spread the word - 2 new PhD positions, one fully funded and one self-funded, with us at Durham and @clarahowcroft.bsky.social at Northumbria Uni! We are looking for people with interdisciplinary experience (biology, computer vision, engineering) and interest to work across disciplines.

Hi Nancy, you can find symbiosis posts on the #Symbiosky feed/tag. Great to see you here!

A dual insect symbiont and plant pathogen improves insect host fitness under arginine limitation | mBio Unlike obligate symbionts that are permanently associated with their hosts, facultative symbionts rarely show direct nutritional contributions, especially under nutrient-limited conditions.

New study from my lab and former grad Dr. Kwak shows Liberibacter psyllaurous, a dual insect symbiont and plant pathogen, boosts psyllid fitness by providing essential nutrients like arginine.
