The Oxford Nanopore MinION as a Versatile Technology for the Diagnosis and Characterization of Emerging Plant Viruses.

The emergence of novel viral epidemics that could affect major crops represents a serious threat to global food security. The early and accurate identification of the causative viral agent is the most important step for a rapid and effective response to disease outbreaks. Over the last years, the Oxford Nanopore Technologies (ONT) MinION sequencer has been proposed as an effective diagnostic tool for the early detection and identification of emerging viruses in plants, providing many advantages compared with different high-throughput sequencing (HTS) technologies.

Traditional Approaches and Emerging Biotechnologies in Grapevine Virology.

Environmental changes and global warming may promote the emergence of unknown viruses, whose spread is favored by the trade in plant products. Viruses represent a major threat to viticulture and the wine industry. Their management is challenging and mostly relies on prophylactic measures that are intended to prevent the introduction of viruses into vineyards.

Small Non-coding RNA in Plants: From Basic Science to Innovative Applications.

Plants possess an arsenal of different classes of small RNAs (sRNAs) of variable size, which play a regulatory role in a multitude of physiological and pathological processes via transcriptional or post-transcriptional gene silencing. The hard challenges that agriculture will face in the next few decades, such as an increasing demand for agrifood production related to the global increase in population, have stimulated the development of innovative biotechnological approaches in agriculture. In this regard, the use of artificial sRNAs has already been exploited successfully for many purposes, including control of severe plant diseases, improvement of genetic and agronomic traits of cultivated species, and increasing the nutritional value of plant foodstuffs.

Androgen Deprivation Freezes Hormone-Sensitive Prostate Cancer Cells in a Reversible, Genetically Unstable Quasi-Apoptotic State, Bursting into Full Apoptosis upon Poly(ADP-ribose) Polymerase Inhibition.

Androgen deprivation therapy (ADT) is a powerful treatment for metastatic hormone-sensitive prostate cancer (mHSPC) patients, but eventually and inevitably, cancer relapses, progressing to the fatal castration-resistant (CR)PC stage. Progression implies the emergence of cells proliferating in the absence of androgen through still elusive mechanisms. We show here for the first time that ADT induces LNCaP mHSPC cells to collectively enter a metastable quasi-apoptotic state (QUAPS) consisting of partial mitochondrial permeabilization, limited BAX and caspase activation, and moderate induction of caspase-dependent dsDNA breaks; despite this, cells maintain full viability.

The Virome of 'Lamon Bean': Application of MinION Sequencing to Investigate the Virus Population Associated with Symptomatic Beans in the Lamon Area, Italy.

'Lamon bean' is a protected geographical indication (PGI) for a product of four varieties of bean ( L.) grown in a specific area of production, which is located in the Belluno district, Veneto region (N.E.
