Characterization and visualization of global metabolomic responses of Brachypodium distachyon to environmental changes

This study characterizes Brachypodium distachyon metabolomic responses to environmental changes using LC-MS/MS and identifies condition-specific metabolic biomarkers.

Size-dependent susceptibility of lake phytoplankton to light stress: An implication for succession of large green algae in a deep oligotrophic lake

The study examines how light stress affects phytoplankton of different sizes in Lake Biwa, finding that larger cells are more resistant to photodamage due to lower chlorophyll-a concentrations.

Seroepidemiological survey on pigs and cattle for novel K88 (F4)-like colonization factor detected in human enterotoxigenic Escherichia coli

The paper reports antibodies in pigs and cattle against a novel K88-like colonization factor from human ETEC, suggesting zoonotic potential and the need for One Health approaches.

A pair of effectors encoded on a conditionally dispensable chromosome of Fusarium oxysporum suppress host-specific immunity

The paper identifies a pair of effector genes on a CD chromosome in F. oxysporum that suppress Arabidopsis immunity, contributing to host specificity.

Development of photosynthetic carbon fixation model using multi-excitation wavelength fast repetition rate fluorometry in Lake Biwa

The paper develops a model to estimate phytoplankton GPP using FRRf with multi-excitation wavelengths and compares it to 13C measurements in Lake Biwa.

Ligand-directed two-step labeling to quantify neuronal glutamate receptor trafficking

This paper introduces a method to label and quantify glutamate receptors in neurons, revealing unique trafficking features of AMPARs and extending the approach to NMDARs.

Deglycosylation of isoflavone C-glucoside puerarin by combination of two recombinant bacterial enzymes and 3-oxo-glucose.

This study identifies and characterizes two bacterial enzymes, DgpA and DgpB-C complex, that work together with 3-oxo-glucose to degrade the C-glucoside puerarin through a β-elimination mechanism.
