Phenotypic Florfenicol Resistance in floR‐Harbouring Flavobacterium psychrophilum Isolates (CC‐ST90): A Case Study From Danish Freshwater Rainbow Trout Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).

Enhanced exonuclease–Cas9 systems promote multiple nucleotide deletions with higher efficiency and broader targeting scope in plants

Journal of Integrative Plant Biology, EarlyView.
Cas9 preferentially generates small indels. By tethering an exonuclease and a DNA‐binding domain (DBD) to Cas9, the Exo‐DBD‐Cas9 system efficiently promotes multiple nucleotide deletions. These expanded deletions enable effective disruption of miRNA‐mediated regulation and relieve translational repression through targeted editing of 3′ untranslated ...

A novel Cas12b cytosine base editor enables efficient C‐to‐T base editing in the rice genome

Journal of Integrative Plant Biology, EarlyView.
The base editor dAaCas12b accurately induces C‐to‐T mutations in rice. It recognizes unique TTTV DNA motifs with a wider editing window, and its optimized guide RNA boosts efficiency, expanding crop gene‐editing resources.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, EarlyView.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Complete organellar genomes of Cystophora brownii: Insights into mitochondrial and plastid structure and evolution in brown algae

Journal of Phycology, EarlyView.
Abstract Cystophora (order Fucales) is one of the most diverse genera of habitat‐forming brown algae and is endemic to temperate reefs of Australia and New Zealand. Species in this genus form complex habitat structures that support diverse marine communities and contribute to coastal productivity. However, Cystophora spp.

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Mitogenome structure and phylogenomics of the order Thoreales (Nemaliophycidae, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract Organelle genomes offer a powerful tool for red algal evolutionary studies. Although the number of Rhodophyta genomes has increased substantially over the past 2 decades, only two mitochondrial genomes have been reported for the red algal order Thoreales.

A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, EarlyView.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.
