Pangenome Analysis of the Plant Pathogen Pseudomonas syringae Reveals Unique Natural Products for Niche Adaptation

Angewandte Chemie, EarlyView.
A pangenome analysis of the plant pathogen Pseudomonas syringae reveals two novel natural product families that facilitate niche adaptation. Comprehensive genomic and chemical analyses uncover unique biosynthetic gene clusters linked to host specificity and environmental fitness.

Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

American Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

TAPIR enables high-throughput estimation and comparison of phylogenetic informativeness using locus-specific substitution models [PDF]

arXiv, 2012
Massively parallel DNA sequencing techniques are rapidly changing the dynamics of phylogenetic study design by exponentially increasing the discovery of phylogenetically useful loci. This increase in the number of phylogenetic markers potentially provides researchers the opportunity to select subsets of loci best-addressing particular phylogenetic ...

Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis

American Journal of Botany, EarlyView.
Abstract Premise Species complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species‐based scientific questions,

Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria

Angewandte Chemie, EarlyView.
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Expanding the Tyrosine Kinase Domain of CSF1R? A Case Report From an Adult‐Onset Leukoencephalopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), also termed hereditary diffuse leukoencephalopathy with spheroids‐1 (HDLS1), results from mutations in the CSF1R gene and leads to progressive leukoencephalopathy.

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

Angewandte Chemie, EarlyView.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

Angewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

Alterations in gut microbiota and metabolites contribute to postoperative sleep disturbances

Animal Models and Experimental Medicine, EarlyView.
In this study, we classified postoperative patients into poor sleepers (PS) and good sleepers (GS) based on the bispectral index (BIS), and transplanted their fecal microbiota to pseudo‐germ‐free rats to analyze the sleep changes in rats and the potential mechanism.
