Heatwaves, poor diets, and parasitoids all stress insects, but not always in expected ways. New paper with
@jinlinchen.bsky.social
finds that Drosophila exposed to parasitoids survive extreme heat better than predicted. royalsocietypublishing.org/doi/10.1098/...

How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Conceptual overview of hierarchical orthologous groups. An example of one HOG, or gene family. A Species tree with four taxa: plant (green), fish (blue), human (orange), and mouse (yellow), each with one or more genes. B The implied gene tree, dubbed โ€œHOG tree,โ€ and inferred nested HOG composition. Duplication nodes (red) can be deduced based on the species tree topology and clusters of homologous genes at each level. Ancestral genes from which the HOGs descended are shown in gray. C HOGs returned at different taxonomic levels. Consider a gene family that was present in the last eukaryotic common ancestor (LECA). At this level, a single HOG encompasses all genes descending from that ancestral gene. At the Vertebrata level, this gene underwent duplication, leading to two distinct copies, i.e., HOGs. At the Mammalia level, a second duplication further subdivides one of these HOGs, showing how deeper HOGs split into nested subHOGs at more recent levels. The HOG composition implies that a loss event occurred after the mammalian speciation

On the cover: A phoronid (Phoronis australis) extending its crown-like feeding organ, the lophophore, from its tube on the seabed. These sedentary marine invertebrates belong to the spiralian branch of bilaterian animals. For over a century, their closest relatives have been debated, with competing hypotheses linking them to either brachiopods or bryozoans. In this issue, Lewin et al. present a chromosome-level genome of P. australis and reveal that it shares seven derived chromosome fusions with bryozoans. This provides rare, sequence-independent evidence supporting bryozoans as the closest relatives of phoronids and offers new insights into the evolution of genome structure and animal body plans.

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.

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 ๐Ÿฆ , not so if you're multicellular ๐Ÿ๐ŸŒฑ๐Ÿ„. www.nature.com/articles/s41... 1/9
