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.

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!

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

Hardly new info, but BSky should know: Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply. Thank you, little guardian molluscs. 🧪🌏🚰

To me it is vertical as there is a direct parent-offspring transmission (via the haploid stage). VT can be uniparental or biparental. Sexual transmission (to me) is distinct: from parent A into parent B (and then sometimes vertically).
