Nissolia brasiliensis as a non-nodulating model legume The nitrogen-fixing root nodule symbiosis (RNS) is specifically formed by four orders of angiosperms. The largest of these four orders include the legume family, the Fabaceae. Among legumes, historica...

Leafy liverwort genomes shed light on the evolution of ericoid symbiosis Mycorrhizal symbiosis has been fundamental to colonization of terrestrial ecosystems by plants, influencing population dynamics, biogeography, and their evolution. The emergence of the ancient arbuscu...

[🚨Pre-print alert🚨] Excited to share our findings on the enigmatic ericoid mycorrhizal symbiosis.

🔴For the first time we provide evidence that ericoid mycorrhizae evolved from ancestral
arbuscular mycorrhizae through the co-option nutrient-dependent regulation 👇!

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity Land plants include angiosperms, bryophytes, lycophytes and ferns, each of which may deploy distinct strategies to resist pathogens. Here, we investigate fern-pathogen interactions by characterizing n...

Conservation of symbiotic signaling since the most recent common ancestor of land plants | PNAS Plants have colonized lands 450 million years ago. This terrestrialization was facilitated by developmental and functional innovations. Recent evo-...

Really pleased to transition from 2024 to 2025 with Tatiana Vernie's work on the evolution of the common symbiosis pathway published @pnas.org 🔽

We finally demonstrate that ☘️ have maintained a genetic pathway to engage with🍄for half a billion years!

This study is the result of a large community effort, and had at its core @PAFTOL and the Genomics for Australian Plants consortium + a lot of contributions from different groups all over the world. Full resources at: zenodo.org/records/1377...

However, only a few cases of conflict with current classification. It is actually amazing to see how robust grass classification has been over many decades, thanks to the careful groundwork done by generations of grass taxonomists! +

We inferred a nuclear phylogeny of grasses with > 1100 tips, covering all but two tribes, with 21 genera sequenced for the first time. Incongruence among gene trees was common, with evidence of frequent ILS and repeated reticulation. +

A nuclear phylogenomic tree of grasses (Poaceae) recovers current classification despite gene tree incongruence Grasses (Poaceae) comprise c. 11 800 species and are central to human livelihoods and terrestrial ecosystems. Knowing their relationships and evolutionary history is key to comparative research and .....

Very happy to see this out! A big thanks to everyone involved, especially Jan Hackel, Bat Vorontsova, Toby Kellogg, Robert Soreng, Bill Baker and P-A Christin!
