Sea sandwort (Honckenya peploides) genome update - first Nanopore flow cell looking pretty good. Dormant shoots were collected from under beach sand in Denmark. A salt tolerant species that was the first plant to appear on the volcanic island Surtsey (Iceland), which erupted out of the sea in 1963.

Our paper on a chromosome-level genome of the carnivorous #butterwort plant #Pinguicula gigantea and other species is now published on bioRxiv ! Exciting to get this project close to done 😀 See the preprint here: www.biorxiv.org/content/10.1...

Cool new work! Some lineages experiencing ancient whole-genome duplications seem to hold on to their duplicate genes for a really long time & keep accumulating homoeologous exchange events! Runs counter to early models where gene loss is expected to be rapid post-WGD academic.oup.com/gbe/advance-...

Looking at new criticism and response of an argument for selection in ancient DNA data, I reflected on the huge extent that immunity now matters in our understanding of human evolution.

FYI, we run PSMCs against self-Masurca assemblies of Illumina reads, as well as against our reference genome. Clermontia spp. are rather poorly divergent which makes the reference genome approach OK, so long as coverage OK. Mapping Cyanea, Delissea and Brighamia to Clermontia not advisable ;)

Will be happy to talk shop w you about other findings we have .. trees, PCAs, F3 analyses, NeighborNet (all of these just complementary w each other and ADMIXTURE) .. but also PSMCs

Here’s the other - needs some manual adjustments tho. This work done by expert PhD student Michaela Richter 😀

Here’s one haplotype .. 14 chrs

Still working on it! We just generated two new assemblies - phased haplotypes - using HifiAsm with the ONT flag plus our HiC reads. Such a big step means we need to re-call our SNPs .. on both haplotypes, independently

Aye-ayes are clearly unusual, but @glom.bsky.social @3rdreviewer.bsky.social &co show that they also have an unusual pattern of #MutationBias; older females transmit more mutations than males. This is a first for mammals, raising questions about other #lemurs 🧪 @plosbiology.org plos.io/40SR4kj

The Droseraceae issue arises if one wants a monophyletic Drosera

The NeighborNet doesn’t help much to discern admixture vs other sources of homoplasy; it’s a summary of all splits that may imply any source incongruence. It does reflect the admixture graph in this case. Also in the Stachys/Hawaiian mint case I posted

Oops, I meant is Nepenthes a monophyletic taxon sister to Droso/Triphyo+Ancistro or is it paraphyletic to Droso/Triphyo+Ancistro .. both. Sorry 😬

For example, in this study I’ll be publishing soon, what is the monophyletic taxon to which Nepenthes belongs? Nepenthes itself is monophyletic - but does it form a clade with Drosophyllum/Triphyophyllum+Ancistrocladus, or a clade with “Droseraceae”? Neither. A NeighborNet reveals the same

Panel (a) here shows why the NeighborNet in panel (e) is the way it is - tree-defying allopolyploidies. In fact, any new phylogenomics study (e.g., based on Angiosperm353 loci) that includes allopolyploids .. and that publishes only trees… is, sadly, immediately “wrong”

Please don’t 100% ignore this paper because of its NeighborNet 🥹😅 www.nature.com/articles/s41...
