    The advent of CRISPR/Cas9 technology has revolutionized genome editing, enabling the attainment of once-unimaginable goals. CRISPR/Cas’s groundbreaking attributes lie in its simplicity, versatility, universality, and independence from customized DNA-protein systems, erasing the need for specialized expertise and broadening its scope of applications. It is therefore more and more used for genome modification including the generation of mutants. Beyond such editing scopes, the recent development of novel or modified Cas-based systems has spawned an array of additional biotechnological tools, empowering both fundamental and applied research. Precisely targeting DNA or RNA sequences, the CRISPR/Cas system has been harnessed in fields as diverse as gene regulation, deepening insights into gene expression, epigenetic changes, genome spatial organization, and chromatin dynamics. Furthermore, it aids in genome imaging and sequencing, as well as effective identification and countering of viral pathogens in plants and animals. All in all, the non-editing aspect of CRISPR/Cas exhibits tremendous potential across diverse domains, including diagnostics, biotechnology, and fundamental research. This article reviews and critically evaluates the primary CRISPR/Cas-based tools developed for plants and animals, underlining their transformative impac

    Cell wall remodeling mediated by specific PME genes plays a role in grapevine response to Botrytis cinerea

    Botrytis cinerea (Bc) is one of the main pathogens affecting the cultivated grapevine. A key role in grapevine tissue colonization is played by cell wall (CW) remodeling driven by CW Modifying Enzymes (CWMEs), expressed both by the host and the pathogen. Their action can impact CW integrity and trigger specific immune signaling, thus influencing Bc infection outcome. To further characterize the role of the CW in the grapevine response to Bc, two contrasting genotypes in their resistance to the fungus were artificially inoculated at full bloom. RNA-seq analysis and biochemical characterization of the CW and its modification in samples collected at 24 hours post-inoculation highlighted significant differences between genotypes. A gene set enrichment analysis indicated several over-represented categories upon infection, with a general down-regulation of those genes related to CW organization and pectin modification, mostly in the resistant genotype. Within the down-regulated CWMEs, Pectin Methyl-Esterase (PME) genes were found highly represented. Unlike, VviPME10 was significantly induced upon infection and was further characterized since its putative ortholog in Arabidopsis was associated with resistance to Bc. VviPME10 promoter hosts several predicted binding sites for VviWRKY3, a defense-associated transcription factor, as highlighted by DAP-seq analysis. This evidence is under confirmation by luciferase assays. In addition, the artificial inoculation with Bc of leaves from six VviPME10 knock-out (KO) edited lines showed significantly larger lesion areas when compared to control plants at 5 dpi. Together, these results suggest that pectin modification, mediated by VviPME10, plays an important role in the grapevine response to Bc

    Health determinants in italian type 2 diabetes Mellitus (T2DM) patients : a critical gender differences analysis

    Different studies described the important role of wellbeing, self-care and self-efficacy (i.e. health determinants) to achieve best health outcomes in Type 2 Diabetes Mellitus (T2DM) patients. However, literature has paid little attention to highlight the possible gender differences related to the T2DM perception of those health determinants. For these reason, the aim of this study was to describe T2DM patients' gender differences related to their wellbeing, self-care and self-efficacy. This study was performed by a secondary analysis of data from a cross-sectional research, conducted in an outpatient setting in Northern Italy. Data was collected from March 2014 and July 2016 in a cohort of 115 T2DM outpatients, aged from 60 to 91 years (mean = 69.78 \ub1 7.11). Our results showed that men perceived more general wellbeing than women, and more diabetes specific self-efficacy. No differences seemed to be related to self-care. Indeed, the stratification by gender of the bivariate analysis allowed to identify many peculiarities related to wellbeing domains and self-efficacy. This study had a pioneering nuance in Italian assessment of T2DM health determinants, and it could have a number of future implications. Further empirical researches should provide more information to deeply understand the T2DM patients' peculiarities, which could help nurses to improve a personalized care delivery
