'Well over a 100k people fled the country seeking asylum. Among them was a young geneticist named George Rédei, who headed for the Austrian border with a small vial of seeds tucked in his pocket.
The seeds belonged to a spindly weed in the mustard family called Arabidopsis thaliana.'
How a humble weed became a superstar of biology
Arabidopsis thaliana was always an unlikely candidate for the limelight. But 25 years ago, the diminutive thale cress launched the botanical world into the molecular era.

After 13 years in the US, I’ve made the difficult decision to leave. Having packed up everything and rethought about priorities, rather painstakingly, while I’m sad to leave the life I’ve made here, I’m also relieved that I won’t have to plan my life around immigration policies anymore.

RNA:DNA hybrids increase at DSBs, crucial for repair, but form without RNA polymerase recruitment. Discover insights on hybrid accumulation. PMID:40447771, Nat Cell Biol 2025, @NatureCellBio https://doi.org/10.1038/s41556-025-01669-y #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Transcriptional repression facilitates RNA:DNA hybrid accumulation at DNA double-strand breaks | Nature Cell Biology
RNA:DNA hybrids accumulate at DNA double-strand breaks (DSBs) and were shown to regulate homologous recombination repair. The mechanism responsible for the formation of these non-canonical RNA:DNA structures remains unclear although they were proposed to arise consequently to RNA polymerase II or III loading followed by DSB-induced de novo transcription at the break site. Here, we found no evidence of RNA polymerase recruitment at DSBs. Rather, strand-specific R-loop mapping revealed that RNA:DNA hybrids are mainly generated at DSBs occurring in transcribing loci, from the hybridization of pre-existing RNA to the 3′ overhang left by DNA end resection. We further identified the H3K4me3 reader spindlin 1 and the transcriptional regulator PAF1 as factors promoting RNA:DNA hybrid accumulation at DSBs, through their role in mediating transcriptional repression in cis to DSBs. Altogether, we provide evidence that RNA:DNA hybrids accumulate at DSBs occurring in transcribing loci as a result o
