Key Highlights
•
This study demonstrates that a salt bridge pre-arranges the structure of the ABC transporter BmrA, which is essential for proper nucleotide-binding domain (NBD) dimerization. The finding offers a mechanistic insight into how membrane transporters are primed for function, which is relevant for understanding drug resistance in pathogens and cancer cells.

Research reveals that host plant associations and environmental filtering jointly shape the genome size of fungal pathogens, with host effects strongest in native pathogens. This discovery provides a hierarchical framework for predicting how diseases might spread under global change, which is critical for managing plant health and food security.
