🚀We’re excited to share our new paper in Bioinformatics!

We introduce a user-friendly toolkit that implements our novel DeNoFo file-format for standardised annotation of de novo gene detection workflows — enabling reproducible methodology descriptions and easier dataset comparison across studies.

🧩 Thrilled to share our new paper in @genomebiolevol.bsky.social !

We present a comprehensive review of de novo gene emergence — providing a classification of current detection methods and a roadmap for addressing major challenges in the field of gene birth from non-genic sequences.

The best part of 2025 is that, unexpectedly, Lucy became part of our family. She brings us so much joy.

Beam Danneels continues at the #biodiversity25 with a presentation about resistant chemical pollutants and induced defenses in #marine_mammals (#chemical_defensome, Chad). Cetaceans lost 2 keys TF involved in the ChD. They have developed a different path. Comparative genomics gave us some insights.

Sam Speak closes the session at the #biodiversity25 with a presentation about #tilapia and the gene positive #selection for saline environments. There are 70 tilapia species with variation in saline tolerance. They sequenced several genomes within this group finding twelve positive selected genes.

We close the #biodiversity25 conference with a keynote presentation by Ute Hentschel Humeida about the basis of #sponge #symbiosis. “Life has evolved in a sea of microbes”. Microbial diversity already existed before the diversification of Eukaryotes. Host-microbes symbiosis appeared early in time.

Elisa Ramos brings us a presentation about #gulls at the #biodiversity25. The large white-headed gulls lineage has one of the faster #radiation processes of the birds of the northern hemisphere. LarOmics project aims to elucidate the genetic base of the gull #evolution.

Niklas Wahlberg opens last day session at the #biodiversity25 with a wonderful presentation about diversification in #Lepidoptera. More than 1000 Lepidoptera #genomes have been sequenced! Some families have more than 100 reference genomes. They have been able to learn many things from them.

Amanda Gardiner follows at the #biodiversity25 with a presentation about #genetic_diversity in sharks, rays and other vertebrates. She analyzed ROH, homozygous regions in vertebrates genomes produced by the VGP. Critically endangered species have more frequently long ROH than other species.

Ashwini V. Mohan follows at the #biodiversity25 presenting about the #limbless Layard’s snake skink. Snakes and caecilians lost their limbs due variations in one gene, but limbless #lizards have multiple evolutionary paths. They sequenced the Nessia layardi genome (1.55Gb) native to SriLanka.

Simona Buonanno closes the 2nd day session at #biodiversity25 presenting benthic genomes in #ascidians. Botryllus schlosseri is a #species_complex. They sequenced 9 ascidian species, including 2 clades of B. schlosseri. BUSCO was higher than 90% for all the genomes.

Claire Merot opens the afternoon session at the #biodiversity25 with a presentation about the structural genetic diversity across the tree of life. Structural variants (SVs) are in order de magnitude higher than SNPs. TEs accounts for many SVs. SVs are different across different lineages.

Camilla Mazzoni follows at the #biodiversity25 with a presentation about #sloths. Analysis of these genomes revealed that sloths have the higher content of LTR/copia in mammals, some impacting metabolic mitochondrial genes. Genomic studies can help to implement more efficient conservation actions.

Callum Thomas follows in the afternoon session at #biodiversity25 talking about the development of a #black_soldier_fly #pangenome. They can be used to produce protein for animals feeding. They can be fed by food waste. They are building a pangenome with individuals from different populations.

Eniko Kiss closes the symbiosis genomics session at the #biodiversity25 with a presentation about #convergent_evolution. Mycorrhiza symbiosis is a good example of convergent evolution. Gene family analysis failed to find gene gains rather than losses. PCOC & ESL-PSC methods were used to overcome it

Merce Montoliu brings us a presentation about wonderful #lichens at the #biodiversity25. Lichens are associations between mycobionts (fungi), photobionts (green algae or cianobacteria) and microbiomes. 38 different lichens were sequenced in DToL & ASH. Results show complex multiorganismal scenarios

Jose V. Lopez follows at the #biodiversity25 presenting about the giant barrel #sponge genome. We are facing massive extinction event in marine reefs so we need to study sponges before they disappear. Sponges have distinctive #symbiotic microbiomes providing important ecosystem services.
