Sweet basil ( L.) downy mildew disease (DM) caused by is a worldwide threat to the basil industry due to the lack of natural genetic resistance in sweet basil germplasm collections. In this study, we used CRISPR-gene editing to modify the sweet basil DM susceptibility gene (). Gene-edited plants challenged with displayed a significantly reduced susceptibility to DM, based on phenotypic disease indices and on pathogen load. These results suggest that plays a role in conditioning DM susceptibility, similar to that observed for the gene in Arabidopsis. These results demonstrate the utility of CRISPR-gene editing in enhancing DM resistance and contributing to sweet basil breeding programs.

The Nipah virus (NiV), a highly pathogenic zoonotic virus of the family, poses significant threats with its alarming mortality rates and pandemic potential. Despite historical cases, effective therapeutics remain elusive, prompting urgent exploration of potential antivirals. In this study, a structure-based virtual screening approach was employed to evaluate 690 metabolites sourced from ten medicinal plants () for their antiviral activity against Nipah virus proteins.

Background And Purpose: The study explores basil seed mucilage as a bioadhesive carrier for naproxen sodium, demonstrating its ability to enhance solubility when administered rectally. The mucilage, derived from seeds, showed bioadhesive properties and thermal stability, as confirmed by FTIR spectroscopy and X-ray diffraction analysis.
Experimental Approach: Microspheres were prepared using a double emulsion solvent evaporation technique, varying polymer ratios to optimize drug delivery.
