"450 million years ago, brown #algae transitioned from unicellular to simple multicellular forms. This was driven by #HorizontalGeneTransfer from #bacteria... Around 200 million years ago, following the breakup of #Pangea, brown algae underwent significant species diversification"

"the parasites produce molecules that alter the central nervous system of the host. Two proteins were found to be homologous to proteins found in the cricket"

As someone with long term interests in #HorizontalGeneTransfer , I'm really interested in this new research exploring environment-specific selection of #plasmid adaptive traits in #bacteria

'MC132 suppresses the immune system by targeting NF-κB, and it had no known homologs until now. The ERV homologs of MC132 in the human genome are mostly disrupted by mutations, but there is an intact copy on chromosome 4. We found homologs of MC132 in ERVs of apes, monkeys, and bushbaby, but not tarsiers, lemurs or non-primates. This suggests that some primate retroviruses had, or have, an extra immune-suppressing protein, which underwent horizontal genetic transfer between unrelated viruses.'

#Introduction

I’m a Post-doc at the University of Oxford, working on the evolution of bacterial genomes and pangenomes. I’m interested in bacterial cooperation and ecology, and how these might interact with horizontal gene transfer.

I’m on the train to Manchester for the #MicroEvo22 meeting, where I’ll be presenting a poster (no. 17). Looking forward to seeing lots of you there!
