Polyploidization in diatoms accelerates adaptation to warming - Nature Climate Change The authors obtained large-volume individuals of diatom cultures under thermal stress. These polyploids (having more than two sets of chromosomes) are shown to rapidly adapt to high temperatures, high...

Bryophytes hold a larger gene family space than vascular plants - Nature Genetics A super-pangenome analysis incorporating 123 newly sequenced bryophyte genomes reveals that bryophytes exhibit a larger number of unique and lineage-specific gene families than vascular plants.

Gene expression divergence following gene and genome duplications in spatially resolved plant transcriptomes After gene and genome duplications, expression divergence across cell types is not random, and it can be explained by a combination of gene age, gene funct

Rapid establishment of species barriers in plants compared with that in animals Speciation, the process by which new reproductively isolated species emerge from ancestral populations, results from the gradual accumulation of barriers to gene flow within genomes. To date, the noti...

Happy to share #ourlatest.

You may have seen studies investigating how duplicated genes diverge in expression across multiple tissues. Here, we zoomed in in tissues (using #spatial transcriptomic data) to investigate how genes diverge in expression across tissue compartments.

The evolutionary significance of polyploidy - Nature Reviews Genetics Polyploidy occurs frequently but is usually detrimental to survival; thus, few polyploids survive in the long term. Here, evidence linking the short-term evolutionary success of polyploids to environm...

6/46 WGD, like multicellularity, evolved many times in history (see www.nature.com/articles/nrg... by @yvdp.bsky.social et al.), driving species radiations and innovations (like at the roots of vertebrates and angiosperms). In fact, most species either are polyploids or bear signs of ancient WGDs.

This was an insane team effort between Arc and Nvidia that convened machine learning and computational biology researchers across Stanford, UC Berkeley, and UCSF. Especially grateful to Jensen Huang for his belief and support of this vision and labor of love, and the entire Evo 2 team below

Evo 2 is trained on 9.3T tokens of DNA with single-base resolution at 1M token context length 🥳

We release two models with 7B and 40B parameters along with weights, training and inference code, and pretraining data—making this one of the largest fully open AI models available
