New preprint from @sjsnodgrass.bsky.social and our colleagues showing variable fractionation in Zea and Tripsacum post-polyploidy. We welcome your thoughts as we work toward submission to a journal.
www.biorxiv.org/content/10.1...
The latest preprint from the PanAnd project, led by @mcstitzer.bsky.social is out today. We look at genome evolution in the Andropogoneae tribe of grasses. Interesting to see how processes occurring in #maize after #polyploidy may not be a general phenomenon.
www.biorxiv.org/content/10.1...
I totally forgot that in addition to the radical genomics, Michelle put together a website where you can learn about the biology of all the species we looked worked with: mcstitzer.github.io/panand_assem...
On top, five Andropogoneae grass species, from left to right Zea mays subsp. mays, Hemarthria uncinata, Miscanthus sinensis, Sorghum bicolor, Andropogon gerardi. On bottom, a map of the world, with collection sites of Andropogoneae grasses in points. A green background shows the distribution of Andropogoneae grasses throughout tropical and temperate latitudes
On left, a phylogeny of Andropogoneae species, with 14 independent polyploidy origins noted. On right, genome size and repeat content of each assembly. Across all assemblies, average assembly size is 1.9 Gb, and average repeat size is 1.5 Gb.
New preprint featuring my favorite maize-relatives, the Andropogoneae! We sequenced the genomes of 27 species, including lemongrass, kangaroo grass, little and big bluestem, and more -- key species that shape grasslands and prairies worldwide. www.biorxiv.org/content/10.1...
There are now 24 step-by-step guides, explaining how to create these ⬇️ data visualizations with R/ggplot2 - I hope this is a useful resource. Find them all here: joachimgoedhart.github.io/DataViz-prot...
I have written a couple of threads 🧵 on "classic" #PlantScience papers. I always tag them with #PlantScienceClassics , but will also compile them here in this thread: 👇
🎉I am really excited to share that our paper is out. We present PHILO ChIP-seq, a user-friendly and cost-effective platform for high-throughput, low-input chromatin profiling in plants!

By definition, enhancers can activate from a distance. But with increased distance between enhancer and promoter, the activation drops. To study this systematically, we build a synthetic locus: www.cell.com/molecular-ce... 1/12

Cool preprint! How do polyploids lose genes during fractionation/diploidization? Old work in maize pointed to recombination-driven deletions (journals.plos.org/plosbiology/...) but generality was unclear. New evidence this is the more common deletion mechanism! www.researchsquare.com/article/rs-4...
For her PhD work, Carla Bautista in our group discovered that yeast hybrids adapted slower to stressful conditions, and she figured out why. See what she found here. #evolution www.nature.com/articles/s41...

Want to learn about the evolution of brown algae as derived from 60 new genomes? Exciting results of the Phaeoexplorer project:
www.sciencedirect.com/science/arti...
Thrilled to see this paper out! 🎉
We analyzed 470 (!) angiosperm genomes and identified and dated 132 whole-genome duplication events. Importantly, we observed that WGD occurrence dates are not randomly distributed, but clustered at times of major environmental upheaval.
Exciting news! The latest hifiasm release from Haoyu Cheng and Heng Li adds beta support for @nanoporetech.com simplex R10 reads. Initial results look very promising. 🚀

If you've missed hyper-k-mers, this joint work with Lucas who's presenting, @imartayan.bsky.social Antoine Limasset and Yoshihiro Shibuya.
They propose a new way to compact k-mers as super-k-mers or unitigs do, but that improves the bit per k-mer level in the representation and storage.
We are proud to announce a collaboration with UK Biobank to create the world’s first large-scale #epigenetic dataset of 50k participants. The dataset will unlock crucial insights into how #epigenetics drives disease & the breakthroughs to treat them.

By popular request, here's how to add Bluesky replies as your blog's comment section!
This requires some technical know-how for now, but I'm hoping that we see some no-code solutions for this pop up soon, like Ghost or Wordpress plugins.

Just out: @multiqc.info v1.25.2 🎉
This patch release fixes a whole host of bugs, the most important one being for #bcl2fastq 🐛
There are also a host of small additions sneaking in for #ngsbits, #picard, #Nanostat, #Samtools and more - so well worth the update!

Hello! I've made it to bluesky. I never liked Twitter but we'll give this a go!
Starting with Sarcodes sanguinea, aka Snow Plant fungal parasite associated with conifers.
Recorded in UVIVF, I hypothesize that the blue fluorescence is intended to attract bees!
