Omg I dropped the R in embryophytes.

Hope I don’t get my #iamabotanist card revoked.

La lignée des plantes terrestres (embryophytes) s’est individualisée au sein d’organismes photosynthétiques aquatiques. Les études phylogénétiques privilégient une origine unique à partir d’algues vertes, les Charophytes, et + particulièrement les Coléochaetales ou les Charales

La phylogénie nous apprend ainsi que les embryophytes ont une origine unique, que leurs + proches parents sont des algues d’eau douce (charophytes), qu'elles partagent un ensemble de caractères qu’on ne trouve pas chez les charophytes. Les plantes terrestres les + basales sont les bryophytes

A paper in Nature Ecology & Evolution presents a time-calibrated phylogeny of Fungi. This timescale suggests an older age of crown Fungi, as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems. #phylo 🧪
A timetree of Fungi dated with fossils and horizontal gene transfers - Nature Ecology & Evolution
Combining fossil-based and molecular calibrations with data on horizontal gene transfer events, the authors develop a time-calibrated phylogeny of Fungi. This timescale, which integrates analytic uncertainties, suggests an older age of crown Fungi (1,401–896 million years ago), as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems (1,253–797 Ma).

Cette conquête terrestre aurait eu lieu uniquement à partir de lacs, de rivières et de mares. En effet, les algues vertes "sœurs" des embryophytes sont retrouvées dans des milieux d’eau douce, mais pas marins. Leur ancêtre commun aurait donc évolué également en eau douce

Comment estimer l'âge des 1ers embryophytes ? 1ère façon (biologie moléculaire), on situe la sortie des eaux à 500 Ma. Pour ça, on estime la vitesse de mutation des gènes : si 2 plantes ont X différences dues à des mutations, on évalue le temps qu’il a fallu pour que ces X mutations s'accumulent

"Evolution of immunity networks across embryophytes"

Not sure if it's because of #MadLand2023 or @grandpahiro.bsky.social's new paper on LysM in #Marchantia - but right now there are a lot of papers dedicated to the evolution of #PlantImmunity.
This one comes from Inés Ponce de León.
