Out today in Nature: sex without crossovers. Rhynchospora tenuis makes pollen, fertilises and sets seed, yet 0 crossovers in 10,997 pollen nuclei. Chromosome drive and ~87% seed abortion rebuild the mother's genotype, so the offspring are clones. doi.org/10.1038/s415...

It is clear that people are using AI to review papers and grants. Often as a tool, not as an off the bottle answer for review (though some do). One of the signs of this is the detail of the negative comments and the errors, often minor and irrelevant to the conclusions. 🧵

It's not too late to share the clicks from the last “RNA-guided genome protection” @embo.org in Switzerland 🇨🇭 what a great time! A dream come true meeting the RNAi guys that I’ve cited in my works since 2016 🥹 #RNAsky #genomeevolution

Plague Poems @plaguepoems.bsky.social · 12/06/2026
When you see the story about how the world now has its first trillionaire, and when you see the story about how laboratories in Congo have run out of supplies to test for Ebola, it is important to understand that in many ways these are the same story.

Nearly a year after our symposium on Repeat-Induced Point (RIP) mutations, I’m happy to share the fruit of some of our discussions. The fungal RIP hypermutator mechanism has deep eukaryotic roots www.sciencedirect.com/science/arti... We hope to spark interest in this underappreciated mechanism.
Evolution of major eukaryotic genome defense systems.
The figure is organized along two axes representing core mechanistic features (homology recognition, small interfering RNA, and
heterochromatin assembly) and their lineage-specific elaborations. We hypothesize that a recombination-independent DNA
homology recognition system present in the eukaryotic common ancestor facilitated the emergence of both heterochromatin
assembly and small RNA-based repeat silencing. From this conserved ancestral core, lineage-specific gene neofunctionalizations
gave rise to distinct defense pathways: the RdDM pathway in plants; the piRNA and KRAB–ZFP pathways in vertebrates; and the
repeat-induced point mutation (RIP), methylation induced premeiotically (MIP), MSUD, and tandem repeat-induced sexual silencing
(TRISS) systems in filamentous ascomycete fungi. Question marks indicate steps for which the molecular mechanisms remain
unknown.

Dfam Database of Transposable Elements @dfam.bsky.social · 05/06/2026
Dfam 4.0 has been released. With over 7 million TE families spanning 6130 species, Dfam continues to grow through genome sequencing and community submissions. This release also introduces an improved FamDB format, making it easier to obtain only the data you need. Release notes: tinyurl.com/6dzwu4w8

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.
