Microbiota‐Derived Inosine Suppresses Systemic Autoimmunity via Restriction of B Cell Differentiation and Migration

open access: yesAdvanced Science, EarlyView.
Lactobacillus johnsonii and its associated purine metabolite inosine not only restrict systemic B cell differentiation, but also contribute to immune cell infiltration in the kidneys, thereby serving dual functions in mitigating the progression of systemic lupus erythematosus (SLE).

Comparison of Phylogenetic Tree Topologies for Nitrogen Associated Genes Partially Reconstruct the Evolutionary History of Saccharomyces cerevisiae

open access: yesMicroorganisms, 2019
Massive sequencing projects executed in Saccharomyces cerevisiae have revealed in detail its population structure. The recent “1002 yeast genomes project” has become the most complete catalogue of yeast genetic diversity and a powerful ...

Phylogenetic trees: Whither microbiology? [PDF]

open access: yesCurrent Biology, 1996
The direct cloning and sequencing of genes from uncultured microorganisms in a hot spring suggests that the diversity of life on Earth may be far in excess of that estimated from culturable species.

Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

open access: yesAdvanced Science, EarlyView.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

The SITE-100 Project: Site-Based Biodiversity Genomics for Species Discovery, Community Ecology, and a Global Tree-of-Life

open access: yesFrontiers in Ecology and Evolution, 2022
Most insect communities are composed of evolutionarily diverse lineages, but detailed phylogenetic analyses of whole communities are lacking, in particular in species-rich tropical faunas.

Correlation Between Fecal Microbiota and Corticosteroid Responsiveness in Primary Immune Thrombocytopenia: an Exploratory Study

open access: yesAdvanced Science, EarlyView.
This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...

Transforming phylogenetic networks: Moving beyond tree space [PDF]

open access: yesarXiv, 2016
Phylogenetic networks are a generalization of phylogenetic trees that are used to represent reticulate evolution. Unrooted phylogenetic networks form a special class of such networks, which naturally generalize unrooted phylogenetic trees. In this paper we define two operations on unrooted phylogenetic networks, one of which is a generalization of the ...

The GhWL1‐GhH1‐GhGA2OX1 Transcriptional Module Regulates Cotton Leaf Morphology

open access: yesAdvanced Science, EarlyView.
This study identified GhWL1 as a key gene involved in regulating leaf development through analysis of a T‐DNA insertion mutant. The GhWL1‐GhH1 complex is shown to positively regulate GhGA2OX1 by directly binding to its promoter, thereby establishing the GhWL1‐GhH1‐GhGA2OX1 module as a critical pathway in leaf development.

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...
