The fission yeast model system Schizosaccharomyces pombe is used to study fundamental biological processes. To continue to fill gaps in the Sz. pombe gene deletion collection, we constructed a set of 90 haploid gene deletion strains covering many previously uncharacterized genes. To begin to understand the function of these genes, we exposed this collection of strains to a battery of stress conditions. Using this information in combination with microscopy, proteomics and mini-chromosome loss assays, we identified genes involved in cell wall integrity, cytokinesis, chromosome segregation and DNA metabolism. This subset of non-essential gene deletions will add to the toolkits available for the study of biological processes in Sz. pombe. Copyright © 2016 John Wiley & Sons, Ltd.

Argonaute-mediated dual recognition enables the detection of trace single-nucleotide-mutated fungicide-resistant fungal pathogens.

Detection of low-abundance mutations for the early discovery of fungicide-resistant fungal pathogens is highly demanded, but remains challenging. Herein, we developed a dual-recognition strategy, termed PARPA, involving s Argonaute (pfAgo)-mediated elimination of wild-type fungal genes and CRISPR/Cas12a-based amplicon recognition. This assay can detect fungicide-resistant at relative abundances as low as 0.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.

The use of nitrogen-fixing bacteria in agriculture is increasingly recognized as a sustainable method to boost crop yields, reduce chemical fertilizer use, and improve soil health. However, the microbial mechanisms by which inoculation with nitrogen-fixing bacteria enhance rice production remain unclear. In this study, rice seedlings were inoculated with the nitrogen-fixing bacterium R3 (Herbaspirillum) at the rhizosphere during the seedling stage in a pot experiment using paddy soil.

Cellular plasticity, the remarkable adaptability of cancer cells to survive under various stress conditions, is a fundamental hallmark that significantly contributes to treatment resistance, tumor metastasis, and disease recurrence. Oncogenes, the driver genes that promote uncontrolled cell proliferation, have long been recognized as key drivers of cellular transformation and tumorigenesis. Paradoxically, accumulating evidence demonstrates that targeting certain oncogenes to inhibit tumor cell proliferation can unexpectedly induce processes like epithelial-to-mesenchymal transition (EMT), conferring enhanced invasive and metastatic capabilities.

Retrotransposons are highly prevalent in most animals and account for more than 35% of the human genome. However, the prevalence, biogenesis mechanism and function of retrotransposons remain largely unknown. Here, we developed retroSeeker, a novel computational software that identifies novel retrotransposons from pairwise alignments of genomes and decodes their biogenesis, expression, evolution and potential functions.
