The Arabidopsis katamari2 Mutant Exhibits a Hypersensitive Seedling Arrest Response at the Phase Transition from Heterotrophic to Autotrophic Growth

This study shows that Arabidopsis seedlings, including the katamari2 mutant, exhibit a growth arrest response during the phase transition from heterotrophic to autotrophic growth, which is an adaptive stress response rather than a carbon source deficiency.

Propagation path of a flowering cherry (Cerasus x yedoensis) cultivar 'Somei-Yoshino' traced by somatic mutations

The paper traces the propagation path of the Somei-Yoshino cherry cultivar by identifying somatic mutations across 46 clones and clustering them into genetic groups.

Comprehensive analysis of nasal IgA antibodies induced by intranasal administration of the SARS-CoV-2 spike protein

This study shows that multimeric secretory IgA from nasal mucosa provides effective protection against SARS-CoV-2, even when monomeric IgA is non-neutralizing.

Neutralizing antibody levels and epidemiological information of patients with breakthrough COVID-19 infection in Toyama, Japan

This study examines neutralizing antibody levels and epidemiological data of patients with breakthrough COVID-19 infections in Toyama, Japan, finding that Omicron BA.1 variants show minimal neutralization despite prior vaccination.

Evaluation of SARS-CoV-2 isolation in cell culture from nasal/nasopharyngeal swabs or saliva specimens of patients with COVID-19

This study evaluates SARS-CoV-2 isolation efficiency from nasal/nasopharyngeal swabs and saliva, finding lower efficiency in saliva due to inhibitory factors like lactoferrin and amylase.

Activation of SARS-CoV-2 by trypsin-like proteases in the clinical specimens of patients with COVID-19

This study examines how trypsin-like proteases affect SARS-CoV-2 infectivity in clinical specimens, finding significant increases for the delta variant compared to omicron.

Comprehensive Analysis of Peptide-Coding Genes Identifies an LRR-only Microprotein That Regulates Reproductive Organs in Marchantia polymorpha

This study identifies an LRR-only microprotein, MpSGF10B, that regulates reproductive organ development in Marchantia polymorpha by affecting antheridiophore formation.

Stomatal regulators are co-opted for seta development in the astomatous liverwort Marchantia polymorpha

The paper shows that a Ia-IIIb bHLH TF module regulates seta development in liverwort Marchantia polymorpha, similar to its role in stomatal formation in stomatous plants.

A rapid and universal liquid chromatograph-mass spectrometry-based platform, refmAb-Q nSMOL, for monitoring monoclonal antibody therapeutics

This paper introduces a rapid and universal LC-MS-based platform for quantifying monoclonal antibodies, offering a scalable alternative to traditional ligand binding assays.

Virological characteristics of SARS-CoV-2 BA.2 variant

This study compares the virological characteristics of SARS-CoV-2 BA.2 and BA.1 variants, finding BA.2 has higher transmissibility, different antigenicity, greater replicative capacity, and higher pathogenicity in hamsters.

Stomatal density affects gas diffusion and CO2 assimilation dynamics in Arabidopsis under fluctuating light

The paper examines how stomatal density affects gas diffusion, CO2 assimilation, and biomass production in Arabidopsis under fluctuating light conditions.

GUN1 regulates tetrapyrrole biosynthesis

This study identifies GUN1's role in chloroplast-to-nucleus retrograde signaling by showing it binds heme, affects tetrapyrrole biosynthesis, and enhances FC1 activity.

Efficient CRISPR/Cas9-based genome editing and its application to conditional genetic analysis in Marchantia polymorpha

This study develops efficient CRISPR/Cas9 vectors for genome editing in Marchantia polymorpha, achieving over 70% editing efficiency and enabling conditional genetic analysis.
