We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics.

The #Drosophila Dscam1 gene generates 10000s of isoforms, but only a small fraction supports neuronal functions. This study shows that #fitness & #immunity are the likely primary evolutionary drivers of Dscam1 isoform diversity in #arthropods @plosbiology.org 🧪 plos.io/4gp8cWd
Top: Dscam1 gene structure and isoform diversity in pancrustacean species. Top: Schematic diagrams of Drosophila melanogaster Dscam1 gene and protein structure. The variable exons or domains are shown in color, while the constant exons or domains are shown in gray. Middle: Phylogenetic distribution of Dscam1 isoform diversity. A phylogenetic tree of Pancrustacean species is shown in the lower panel. The upper panel shows distribution of the number of exons in variable exon 4, exon 6, or exon 9 clusters in Pancrustacean species, with variable exon clusters shown in different colors. The middle panel shows distribution of the number of potential ectodomains diversity, where species with a special number of diversities are highlighted. Bottom: Reducing the Dscam1 diversity affects adult survival upon Beauveria bassiana infection. Survival curves after Triton or B. bassiana infection for wild-type and exon 4 (left), exon 6 (middle), and exon 9 (right) mutants are shown, respectively. The Triton groups (control) are represented by solid lines, while the B. bassiana groups are represented by dashed lines.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Curious to see what happen if all genome were re-annotated by helixer only.

"We show that unrelated proteins have a universal tendency towards convergent evolution of secondary and tertiary motifs, causing an excess of high-scoring FP alignment... previous methods routinely overestimate significance by up to six orders of magnitude."

Protein structure alignment significance is often exaggerated
Machine learning has generated millions of high-quality predicted protein structures, creating a need for computationally efficient structure search algorithms and robust estimates of statistical sign...

To promote the collection, I’ve launched a designer clothing line where synthetic biology meets aesthetics.

I will give out 100 free limited edition shirts to the first who retweet and order with their handle in the name! Available here → nickdesnoyer.com 🧵(6/7)

If you're new to demographic history inference from population genomics, try this webapp I created to illustrate how dadi fits bottleneck models to site frequency spectra: ryangutenkunst-dadi-two-epoch.hf.space . It even outputs files for submitting to the GHIST competition! ghi.st

OrthoFinder just dropped a major update

It’s faster, more accurate, and ready for thousands of genomes

Let’s break it down (1/10)

New paper out! 🎉

With an innovative approach of CRISPRing a gene mutation on many backgrounds, we provide a proof of concept for how “pan-genetic” analysis can reveal the true extent of genetic networks in a species.

Thanks @plantevolution.bsky.social-lab!

If you are using HapHiC, you could add track from long reads
alignment. It could be false duplication from haplotype or some repeat in the genome.

Preprint on "Improving spliced alignment by modeling splice sites with deep learning". It describes minisplice for modeling splice signals. Minimap2 and miniprot now optionally use the predicted scores to improve spliced alignment.

Long-term flowering-time data on Japanese mountain cherry (recorded since the 9th century!) shows a shift in full-flowering date beginning in the late 19th century.

As the world warms, plants in natural ecosystems and agricultural settings find ways to respond to the heat.

In a new special issue of Science, researchers examine how heat affects plants at multiple scales, from the molecular level to the biosphere. scim.ag/44cSw3Z
Infrared imaging shows heat levels in sun-exposed leaves of Alstonia scholaris from the Australian Wet Tropics. As climate change increases temperatures and the severity of heat waves, both natural ecosystems and agricultural plants are increasingly affected by heat. Examining heat responses at cellular, genetic, physiological, and ecosystem scales, this special issue explores how plants sense and respond to high temperatures.
