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...

Maize and wild relatives show distinct patterns of genome downsizing following polyploidy

Plant genomes are smaller than expected despite the ubiquity of polyploidy due to the process of genome downsizing called fractionation. This process causes loss of DNA sequences, including genes, unt...

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...

The consequences of polyploidy are... well, complicated. A deep dive into polyploidy in a massively successful tribe of grasses. A masterpiece led by Michelle Stitzer, representing the work of a lot of folks on the PanAnd project over last 7 years. www.biorxiv.org/content/10.1...

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...

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...

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. Read more: nanoporetech.com/news/oxford-...
