Blackcurrant reversion virus (BRV) is the most destructive mite-transmitted pathogen in blackcurrants. The understanding of the resistance to BRV is limited, hindering and delaying the selection process. To identify the resistance () gene for BRV resistance, a gene expression analysis based on de novo blackcurrant cv. Aldoniai comparative transcriptome analysis (mock- and BRV-inoculated samples at 2 and 4 days post-inoculation (dpi)) was performed. In this study, 111 annotated clusters associated with pathogenesis according to conservative gene domains were identified. In virus-infected samples, only Cluster-12591.33361 showed significant expression at 4 dpi. The expression profiles of this cluster were significantly associated with the presence of BRV particles in plant tissues, making it a putative gene in the dominant resistance strategy in the BRV- interaction. The newly identified gene _ belongs to the CC-NBS-LRR class and has 63.9% identity with in spp. This study provides new insights on dominant putative genes related to resistance to BRV in , which could aid targeted research and genetic improvement in breeding programs of blackcurrants.

Diarrheal irritable bowel syndrome (IBS-D) is a chronic bowel condition that leads to intestinal dysfunction and is typically accompanied by diarrhea, stomach pain, and abdominal distension. L. polyphenols (RNPs), which are natural plant polyphenols, are the subject of this study, which aims to assess their potential in improving IBS-D and to explore the underlying mechanisms through a network pharmacology analysis and 16S rRNA sequencing.

The 3CL protease (3CL, M) plays a key role in the replication of the SARS-CoV-2 and was validated as therapeutic target by the development and approval of specific antiviral drugs (nirmatrelvir, ensitrelvir), inhibitors of this protease. Moreover, its high conservation within the coronavirus family renders it an attractive therapeutic target for the development of anti-coronavirus compounds with broad spectrum activity to control COVID-19 and future coronavirus diseases. Here we report on the design, synthesis and structure-activity relationships of a new series of small covalent reversible inhibitors of the SARS-CoV-2 3CL.

5-Aminoisophthalic acid and 5-nitroisophthalic acid (5-NIPA) are potential impurities in preparations of 5-amino-2,4,6-triiodoisophthalic acid, which is a key intermediate in the synthesis of the iodinated contrast agent iopamidol. We have studied their mutagenicity in silico (quantitative structure-activity relationships, QSAR) and by the bacterial reverse mutation assay (Ames test). First, the compounds were screened with the tools Derek Nexus™ and Leadscope®.
