The structural biology of CRISPR-Cas systems [PDF]
Prokaryotic CRISPR-Cas genomic loci encode RNA-mediated adaptive immune systems that bear some functional similarities with eukaryotic RNA interference. Acquired and heritable immunity against bacteriophage and plasmids begins with integration of ∼30 base pair foreign DNA sequences into the host genome.

CRISPR-Cas Systems Reduced to a Minimum [PDF]
In two recent studies in Molecular Cell, Wright et al. (2019) report complete spacer integration by a Cas1 mini-integrase and Edraki et al. (2019) describe accurate genome editing by a small Cas9 ortholog with less stringent PAM requirements.

Origins and evolution of CRISPR-Cas systems [PDF]
CRISPR-Cas, the bacterial and archaeal adaptive immunity systems, encompass a complex machinery that integrates fragments of foreign nucleic acids, mostly from mobile genetic elements (MGE), into CRISPR arrays embedded in microbial genomes. Transcripts of the inserted segments (spacers) are employed by CRISPR-Cas systems as guide (g)RNAs for ...

Pflanzen können von einer Vielzahl an Pathogenen befallen werden, die schwerwiegende Krankheiten auslösen und besonders bei Nutzpflanzen zu starken Ernteverlusten beitragen. CRISPR/Cas‐Systeme verändern die Angriffsstellen dieser Pathogene hochpräzise, sodass ein Befall nicht mehr stattfinden kann – eine Entwicklung, die als Revolution in der ...

New CRISPR-Cas systems discovered [PDF]
In bacteria and archaea, CRISPR-Cas adaptive immune systems utilize RNA-guided endonucleases to defend against invasion by foreign nucleic acids of bacteriophage, virus and plasmid origin. In a recent paper published in Nature, Burstein et al. identified the first Cas9 protein in uncultivated archaea and two novel CRISPR-CasX and CRISPR-CasY systems in

Applications of CRISPR–Cas systems in neuroscience [PDF]
Genome-editing tools, and in particular those based on CRISPR-Cas (clustered regularly interspaced short palindromic repeat (CRISPR)-CRISPR-associated protein) systems, are accelerating the pace of biological research and enabling targeted genetic interrogation in almost any organism and cell type. These tools have opened the door to the development of

Annotation and Classification of CRISPR-Cas Systems [PDF]
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas (CRISPR-associated proteins) is a prokaryotic adaptive immune system that is represented in most archaea and many bacteria. Among the currently known prokaryotic defense systems, the CRISPR-Cas genomic loci show unprecedented complexity and diversity.

Insights into the CRISPR/Cas system of Gardnerella vaginalis [PDF]
Gardnerella vaginalis is identified as the predominant colonist of the vaginal tracts of women diagnosed with bacterial vaginosis (BV). G. vaginalis can be isolated from healthy women, and an asymptomatic BV state is also recognised. The association of G.

CRISPR-Cas systems in enterococci
Enterococci are members of the microbiota of humans and other animals. They can also be found in the environment, associated with food, healthcare infections, and hospital settings. Due to their wide distribution, they are inserted in the One Health context.

Diversity and complexity in neural organoids
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
