Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9
nature.com
Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics
Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Chaetognaths have lost gene body methylation and shifted #5mC back to Transposable Elements. This reversion to the ancestral state is coupled with a simplification of DNMT3 architecture. We posit that trans-splicing might compensate. It is an honour to have contributed to this 20y struggle ⛰️.
