Microbial Communities in Biocrusts Are Recruited From the Neighboring Sand at Coastal Dunes Along the Baltic Sea

open access: yesFrontiers in Microbiology, 2022
Biological soil crusts occur worldwide as pioneer communities stabilizing the soil surface. In coastal primary sand dunes, vascular plants cannot sustain due to scarce nutrients and the low-water-holding capacity of the sand sediment.

Massive Horizontal Gene Transfer in Bdelloid Rotifers [PDF]

open access: yes, 2008
Horizontal gene transfer in metazoans has been documented in only a few species and is usually associated with endosymbiosis or parasitism. By contrast, in bdelloid rotifers we found many genes that appear to have originated in bacteria, fungi, and ...

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

The relationships between the isoelectric point and: length of proteins, taxonomy and ecology of organisms

open access: yesBMC Genomics, 2007
Background The distribution of isoelectric point (pI) of proteins in a proteome is universal for all organisms. It is bimodal dividing the proteome into two sets of acidic and basic proteins.

Regions with two amino acids in protein sequences: A step forward from homorepeats into the low complexity landscape

open access: yesComputational and Structural Biotechnology Journal, 2022
Low complexity regions (LCRs) differ in amino acid composition from the background provided by the corresponding proteomes. The simplest LCRs are homorepeats (or polyX), regions composed of mostly-one amino acid type.

The largest reservoir of mitochondrial introns is a relic of an ancestral split gene [PDF]

open access: yes, 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.

Biowaste Composting as a Sustainable Platform for Bacterial CO Production: Evidence From cooS Gene Expression and Microbial Community Profiling

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates, for the first time, the expression of the cooS gene during composting, confirming microbial CO production under mesophilic conditions. The results highlight composting as a novel waste‐to‐biochemicals process, offering a sustainable, low‐carbon pathway for generating carbon monoxide via bacterial CO dehydrogenase activity ...

LUD, a new protein domain associated with lactate utilization. [PDF]

open access: yes, 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

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

open access: yesAdvanced 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,

Demographic History and Genetic Diversity of Rātā Moehau (Metrosideros bartlettii; Myrtaceae), a Critically Endangered Aotearoa New Zealand Endemic Tree

open access: yesEcology 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 ...
