New #ISEPpapers #preprint by @DEEMteam: Re-evaluating the eukaryotic #TreeOfLife with independent phylogenomic data https://www.biorxiv.org/content/10.64898/2026.04.08.717153v1.abstract

"analyses confirm most eukaryotic supergroups previously observed, but suggest different positions for some lineages. Notably, Telonemia clusters with Haptophyta rather than SAR, and Ancyromonadida and Malawimonadida form a monophyletic group at the base of the Opimoda."

New #ISEPpapers! Single‐Cell Transcriptomes and Phylogenomic Analysis of Uncultivated #Oxymonads: Morelia Trznadel et al. https://pmc.ncbi.nlm.nih.gov/articles/PMC13002328/

"Oxymonads are divided into five families in a classification that has remained more or less unchanged for 35 years, but the relationships of these families are unknown... Here, we carry out the first phylogenomic analysis of oxymonads that includes all five families."
