Risk assessment and resistance mechanism of <scp><i>Pseudomonas syringae</i></scp> pv. <scp><i>actinidiae</i></scp> to streptothricins
This study establishes that STs resistance in Psa is mediated by P-SatA-dependent acetylation, with resistant strains incurring substantial fitness penalties that limit their environmental competitiveness. The absence of natural resistance and low cross-resistance to other pesticides highlight STs as a sustainable option for kiwifruit canker management. These findings advance our understanding of metabolic resistance mechanisms in plant pathogens and provide a scientific basis for optimizing STs application to mitigate resistance risks. © 2025 Society of Chemical Industry.
