A fast, easy, and scalable method to assess the properties of site-specific nucleases is crucial to -understanding their in cellulo behavior in genome engineering or population-level gene drive applications. Here we describe an analytical platform that enables high-throughput, semiquantitative interrogation of the DNA-binding and catalytic properties of LAGLIDADG homing endonucleases (LHEs). Using this platform, natural or engineered LHEs are expressed on the surface of Saccharomyces cerevisiae yeast where they can be rapidly evaluated against synthetic DNA target sequences using flow cytometry.

Unlabelled: The Candidate Phyla Radiation (CPR) represents an extensive bacterial clade comprising primarily uncultured lineages and is distinguished from other bacteria by a significant prevalence of insertion sequences (ISs) within their rRNA genes. However, our understanding of the taxonomic distribution and characteristics of these ISs remains limited. In this study, we used a comprehensive approach to systematically determine the nature of the rRNA ISs in CPR bacteria.

Homing genetic elements are a form of selfish DNA that inserts into a specific target site in the genome and spreads through the population by a process of biased inheritance. Two well-known types of homing element, called inteins and homing introns, were discovered decades ago. In this review we describe WHO elements, a newly discovered type of homing element that constitutes a distinct third category but is rare, having been found only in a few yeast species so far.

The description is based on light and scanning electron microscopy performed on two monoclonal cultures. The complete nuclear rRNA clusters and plastid genomes have been sequenced for these two strains and the complete mitogenome for one of them.

Limiting the spread of synthetic genetic information outside of the intended use is essential for applications where biocontainment is critical. In particular, biocontainment of engineered probiotics and plasmids that are excreted from the mammalian gastrointestinal tract is needed to prevent escape and acquisition of genetic material that could confer a selective advantage to microbial communities. Here, we built a simple and lightweight biocontainment system that post-translationally activates a site-specific DNA endonuclease to degrade DNA at 18°C and not at higher temperatures.

() is known as an important mycoparasite and biocontrol fungus and feeds on fungal material by parasitizing other fungi. Recent studies indicate that this species is also an ear rot pathogen in Europe. Here, the complete mitochondrial genome of three strains was sequenced using next-generation sequencing and comparatively characterized by the reported mitogenomes.
