Digging designer genomes

BioTechniques, 2015
Techniques such as Gibson and Golden Gate assembly and homologous recombination in yeast allow researchers to assemble DNA sequences millions of base pairs in length. Sarah Webb investigates the challenges of constructing designer chromosomes and genomes,

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]

, 2004
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

Infection mechanisms of Rhizoctonia cerealis in wheat

iMeta, EarlyView.
We discover that R. cerealis (Rc) is a primary pathogen causing sharp eyespot of wheat after 335 distinct isolates were isolated from 1683 SE‐diseased wheat plants across China over 7 years using a single hyphal tip isolation method. We then generated high‐quality reference genomes via de novo sequencing of five representative Rc isolates and ...

Toward Predicting Pandemic Potential: A Comparative Analysis of Virus‐Host Interactions Between Diverse Influenza A Viruses and the Human Innate Immune System

PROTEOMICS, EarlyView.
ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

Eroded telomeres are rearranged in quiescent fission yeast cells through duplications of subtelomeric sequences

Nature Communications, 2017
How both telomere stability is regulated and dysfunctional telomeres processed in quiescent cells is poorly understood. Here, the authors provide evidence that eroded telomeres in quiescent fission yeast are rearranged by homologous recombination through

An (αβ)2 Architecture of the Arabidopsis thaliana tRNA Splicing Endonuclease Complex: Structural Modeling and Evolutionary Analyses

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The tRNA splicing endonuclease (TSEN) removes introns from precursor tRNAs (pre‐tRNAs) in eukaryotes and archaea, but the architecture and subunit organization of plant TSEN remain poorly defined. Here, we integrated in planta bimolecular fluorescence complementation (BiFC) assays with AlphaFold3 (AF3)‐based structural modeling, molecular ...

Analysis of the indispensable RAD51 cofactor BRCA2 in Naganishia liquefaciens , a Basidiomycota yeast

Life Science Alliance
Identification of the BRCA2 homolog in the Basidiomycota yeast Naganishia liquefaciens reveals the general attributes of fungal BRCA2 and its essential role in Rad51-mediated homologous recombination.

Genealogy-based methods for inference of historical recombination and gene flow and their application in Saccharomyces cerevisiae [PDF]

, 2012
Genetic exchange between isolated populations, or introgression between species, serves as a key source of novel genetic material on which natural selection can act.

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

General Method for Plasmid Construction Using Homologous Recombination

BioTechniques, 1999
We describe a general method for plasmid assembly that uses yeast and extends beyond yeast-specific research applications. This technology exploits the homologous recombination, double-stranded break repair pathway in Saccharomyces cerevisiae to join DNA
