Tracing the path from conservation to expansion evolutionary insights into NLR genes in oleaceae.

The Oleaceae family, encompassing key genera such as Fraxinus (ash trees), Olea (olives), Jasminum (jasmine), Syringa (lilac), and Forsythia, plays a crucial ecological and economic role. Despite their importance, the evolutionary dynamics and immune system adaptations of their NLR (Nucleotide binding leucine-rich repeats) gene family remain largely unexplored. This study employs high-throughput comparative genomics to investigate NLR gene evolution across the Oleaceae family.

Proteomic profiling and pre-clinical efficacy of antimicrobial lithium complex and colistin combination against multi-drug resistant Acinetobacter baumannii.
