Priming Bean Seedlings to Boost Natural Plant Defenses Against Common Bacterial Wilt: Gas Exchange, and Fluorescence Results (Part 2)

This greenhouse study evaluated the effects of two chemical primers for kidney bean seedlings against a bacterial wilt (Curtobacterium flaccumfaciens pv. Flaccumfaciens) (CFF). The premise this was that oxidant would mimic signaling properties radical oxygen species and initiate cascade molecular defenses. factorial included levels foliar chlorine dioxide treatment, inoculation plus supplemental treatments. foliage response variables were gas exchange fluorescence. There 36, 154, 70% reduction in Pn, gs, E, respectively, at 39 DAT when comparing inoculated control to non-inoculated control. lowered leaf temperatures vapor pressure deficit CFF plants. improved compared water Part 1 2 series conclude can activate long-term, systemic acquired resistance (SAR) plants infected with wilt. article also concludes EB treatments caused several inexplicable correlations among responses. A structured proposed as an explanation anomalies due Intuitively, suggests ROS salicylic acid signals suite mechanisms provide universal, multifaceted plant immunity is sustained across crop season.
