Cytokinin arabinosides show increased efficacy in priming tomato immunity and directly restricting energy metabolism in the fungal phytopathogen B. cinerea
Transcriptomic analyses of B. cinerea treated with CK arabinosides revealed significant changes in gene profiles, notably in pathways associated with sugar metabolism. Unlike classical CKs, CK arabinosides do not alleviate growth inhibition under sugar-limited conditions, contributing to their stronger antifungal effects.
