#Microsporidia are #parasites of growing importance. ‪@amjadkhalaf.bsky.social‬ ‪@mblaxter.bsky.social @marakat.bsky.social &co present 40 new genomes from #DarwinTreeofLife sequencing of their arthropod hosts, revealing insights into #tetraploidy & #reproduction @plosbiology.org 🧪 plos.io/48HsAQJ
Top: Prevalence of Microsporidia in DToL insect genomes. Microsporidian genomes recovered from insect hosts, split by taxonomic order. F: female, M: male, U: unspecified sex. Bottom: Simplified proposed generalized lifecycle for Microsporidia. This proposed model posits that each nucleus is a diploid, and that microsporidian reproduction mirrors reproduction in Fungi with stages similar to karyogamy, plasmogamy, and a stable “heterokaryon” (known as a diplokaryon in Microsporidia). Importantly, both the diplokaryotic and monokaryotic phases are parasitic, and species may spend most of their lifecycle in one or the other phase, giving rise to “diploid” and “tetraploid” lineages.

Happy to share the results of a long-haul post-doc project, now online @science.org, aiming at understanding the rules of transgeneration epigenetic inheritance over TEs in plants and its extent and impact in nature. More below!

Transposable elements are vectors of recurrent transgenerational epigenetic inheritance
DNA methylation loss at transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants and significance of this additional system of inheritan...

Here’s an interesting new paper on ROS1, an enzyme that removes DNA methylation and that is POSITIVELY controlled by DNA methylation.
It’s repression during heat stress 🥵🌱 is crucial to suppress transposon mobility! 🧬

Plants repress ROS1 expression to attenuate heat-induced transposon burst - Nature Plants
Plants suppress the DNA demethylase ROS1 under heat stress to limit transposon activation, preventing genome instability. This conserved mechanism balances stress adaptation with genome protection.

Rapid origin and turnover of genomic imprinting by transposable elements
Genomic imprinting, the preferential expression of alleles based on their parent-of-origin, is an epigenetic mechanism that plays a key role in endosp…

Sexual selection drives the speciation of lineages with contrasting mating systems
Repeated shifts in ecological strategies often lead to consistent speciation patterns across phylogenies. One example is the transition from outcrossi…
