Antibiotic resistance in E. coli isolates from wild-living animals

open access: yesBioingeniøren, 2008
This study indicates that wild-living animals can harbour antibiotic resistant bacteria in their microbial intestinal flora, even if they have not been exposed to selection pressure from the usage of antimicrobial agents.

An Escherichia coli Phosphotransferase System Modulates Methylglyoxal Resistance by Regulating Intracellular Potassium

open access: yesMolecular Microbiology, EarlyView.
Escherichia coli can survive methylglyoxal stress by modulating phosphorylation of a regulatory phosphotransferase system, which, in turn, regulates the activity of a potassium/proton antiporter. The constitutive potassium importer Trk also contributes to intracellular potassium levels.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

open access: yesNew Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Structure and sequence evolution in the pennycress (Thlaspi arvense) pangenome

open access: yesNew Phytologist, EarlyView.
Summary Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biodiversity. Harnessing this variation for agriculture hinges on our ability to detect, quantify, catalog, and deploy genetic diversity. Here, we explore seven

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

PlantCTCIP: Chromatin Interaction Prediction Using Convolutional Neural Network and Transformer in Plants

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Chromatin interactions establish spatial proximity between distant regulatory elements and their target genes, significantly influencing gene expression, and phenotypic traits. In this study, we present a plant chromatin interaction prediction model called PlantCTCIP based on Convolutional Neural Networks and Transformer.

A Near Telomere‐to‐Telomere Genome of Belamcanda chinensis Provides Insights Into Genome Evolution and the Biosynthesis of Characteristic Isoflavones

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Belamcanda chinensis is a non‐leguminous medicinal plant rich in bioactive isoflavones; however, the lack of a high‐quality reference genome has limited elucidation of its isoflavone biosynthetic and modification network. Here, we present the first near telomere‐to‐telomere genome assembly of B.

ZmWRKY29 Transcriptionally Represses ZmRBOHC to Attenuate ROS Production and Facilitates Gibberella Stalk Rot Susceptibility in Maize

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Gibberella stalk rot (GSR), caused by the fungal pathogen Fusarium graminearum, severely threatens maize production. However, the molecular mechanisms underlying maize resistance to GSR remain poorly understood. Here, we have identified ZmWRKY29 as a transcriptional repressor induced by F.

Disruption of Asparagine Synthetase Is Associated to Increased Biomass in Lotus japonicus

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Asparagine (Asn) constitutes the major form of nitrogen translocated within Lotus japonicus plants. In this work we use knock‐out (KO) LORE1 mutants‐deficient in the asparagine synthetase gene (LjASN1), which is the most highly expressed ASN gene in plants grown under non‐symbiotic (NS) conditions, but much less expressed under symbiotic (S ...

A Natural LTR Retrotransposon Insertion in the Promoter of GhNAC140‐Dt Boosts Cotton Lint Yield

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Transposable elements (TEs) are fundamental drivers of crop evolution and domestication. Whereas the underlying mechanisms of TE‐mediated gene activation remain poorly understood. Lint percentage is an important yield component in cotton. Here, we report a retrotransposon insertion in the promoter of GhNAC140‐Dt, a secondary wall NAC encoding ...
