Among the cultivated crop species, the economically and culturally important grapevine plays host to the greatest number of distinctly characterized viruses. A critical component of the management and containment of these viral diseases in grapevine is both the identification of infected vines and the characterization of new pathogens. Next-generation high-throughput sequencing technologies, i.

This study examined the chemoselectivity and diastereoselectivity of silyl nitronate alkenyn-nitroethers in Intramolecular Silyl Nitronate Cycloadditions (ISNCs) to produce isoxazole derivatives with interesting medicinal properties. These reactions resulted in the formation of either dihydrofuro[3,4-c]isoxazolines/isoxazolidines and/or alkynyl moieties attached to 2,5-dihydrofuryl carbonyls. This study also discerned the diastereoselectivities of the resulting cyclic adducts and compared them to previous findings.

Article Synopsis
  • Balanced mating type polymorphisms provide insight into the evolution of sexual reproduction strategies in plants, particularly within the Juglandaceae family (like walnuts and hickories).
  • Researchers have identified two distinct Mendelian inheritance mechanisms linked to ancient DNA polymorphisms that dictate whether flowers develop male or female first, showing a 1:1 genetic ratio.
  • A dominant haplotype associated with female-first flowering is linked to a gene related to trehalose-6-phosphate metabolism, suggesting complex regulation of gene expression and hints at sex chromosome-like evolution in these plants.

We describe an outbreak of invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup C in Fiji. We created surveillance case definitions and collected data by using standard investigation forms. Bacterial identification, antimicrobial susceptibility testing, and PCR were performed in Fiji.

Purpose: There is increased use of genomic testing in oncology care. Yet, individuals with hereditary cancer predisposition syndromes (CPS) experience challenges when navigating the lifelong CPS healthcare considerations. The purpose of this study is to describe the healthcare experiences of individuals living with CPS and their perceptions of genomic-informed nursing care.
