I am glad to share the latest paper by Adriel M. Sierra published in ISME Communications
on the "Assembly of nitrogen-fixing bacteria associated with epiphyllous liverworts in fragmented Amazonian tropical forest" doi.org/10.1093/isme...

Assembly and co-occurrence networks of nitrogen-fixing bacteria associated with epiphyllous liverworts in fragmented tropical forests

Abstract. Understanding the spatial dynamics of plant-associated microbial communities is increasingly urgent in the context of habitat loss and the biodiv

a study that changes the paradigm of horizontal gene transfer across kingdoms, led by my former PhD supervisor Bernard Goffinet, congratulations to his team www.nature.com/articles/s41...

I am glad to be part of the largest paper on bryophyte genomics. Spearheaded by Shanshan Dong and Yang Liu ( Fairy Lake Botanical Garden) presents: "A comprehensive super-pangenome analysis, incorporating 123 newly sequenced bryophyte nuclear genomes......"

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 flow stops sooner in plants than in animals

Genomic data indicate when species became reproductively isolated

Un groupe français dont ma collègue Christelle Fraïsse (Université de Lille) fait partie vient de publier un article très intéressant sur les barrières entre les espèces de plantes et d'animaux ! Bravo à Chris, Camille et tous les autres ! www.science.org/doi/10.1126/...

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...

@pourlascience.bsky.social . Le volume parle de la matière noire, du chromosome X inactif. L'article sur la diversité des plantes était fascinant. Notre placette en Darien fait partie de FORESTGEO et nous y ferons certainement des découvertes fascinantes. www.pourlascience.fr/sd/ecologie/...

Comment les champignons et les animaux structurent la diversité des forêts

La dispersion des graines par les animaux et l’interaction avec les champignons jouent un rôle clé dans la répartition des arbres de différentes espèces dans les forêts.

Adriel Sierra defended his PHD. He worked on the impact on fragmentation on plant population genomics and microbial diversity and 2) the relationship between plant metabolome and microbes. His work can be found shorturl.at/DZgCU. Congratulations to Adriel and the best of luck on the way forward. 🌿

I was reading a recent cool paper on the genomics of hornwort sex/"accessory" chromosomes (New Phytologist) and it never ceases to amaze me the tremendous knowledge that Johannes M. Proskauer had about the group. He'd be thrilled to see the hornwort research in this era. www.jstor.org/stable/3241446
