Tracing the paths of modular evolution by quantifying rearrangement events of protein domains
BMC Ecology and EvolutionBackground Protein evolution is central to molecular adaptation and largely characterized by modular rearrangements of domains, the evolutionary and structural building blocks of proteins.

The largest reservoir of mitochondrial introns is a relic of an ancestral split gene [PDF]
, 2010 In eukaryotes, introns are located in nuclear and organelle genes from several kingdoms (ref. 1-4). Large introns (0.1 to 5 kbp) are frequent in mitochondrial genomes of plant and fungi (ref.

LUD, a new protein domain associated with lactate utilization. [PDF]
, 2013 BackgroundA novel highly conserved protein domain, DUF162 [Pfam: PF02589], can be mapped to two proteins: LutB and LutC. Both proteins are encoded by a highly conserved LutABC operon, which has been implicated in lactate utilization in bacteria. Based on

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.ABSTRACT Goniomonads are representatives of Cryptista. They are morphologically and genetically diverse, comprising nine genera described so far. 18S rDNA data has revealed at least one more monophyletic genus‐level lineage, as well as novel species within currently described genera. The molecular diversity of goniomonads is not fully investigated, and

ARAGORN, a program to detect tRNA genes and tmRNA genes in nucleotide sequences [PDF]
, 2004 A computer program, ARAGORN, identifies tRNA and tmRNA genes. The program employs heuristic algorithms to predict tRNA secondary structure, based on homology with recognized tRNA consensus sequences and ability to form a base-paired cloverleaf.

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts
Advanced Science, Volume 13, Issue 24, 27 April 2026.We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,

Exploring nucleo-cytoplasmic large DNA viruses in Tara Oceans microbial metagenomes [PDF]
, 2013 Nucleo-cytoplasmic large DNA viruses (NCLDVs) constitute a group of eukaryotic viruses that can have crucial ecological roles in the sea by accelerating the turnover of their unicellular hosts or by causing diseases in animals. To better characterize the

Ecology and Evolution, Volume 16, Issue 4, April 2026.Rātā Moehau (Metrosideros bartlettii), a critically endangered tree endemic to Aotearoa New Zealand, is represented by only 14 wild individuals. We assembled its first genome, analysed genetic diversity in wild and cultivated individuals and found long‐term population decline and reduced diversity in cultivated plants—providing key insights to support ...

Food Science &Nutrition, Volume 14, Issue 4, April 2026.This study revealed that rumen microbiota significantly influence IMF deposition in Pingliang Red cattle through taxonomic and functional mechanisms. Limosilactobacillus panis and Fibrobacter succinogenes were identified as potential biomarkers for high IMF content.
