Effect of Xylella infection on intervessel PM integrity of PD-susceptible grapevine genotypes (A–C) and PD-resistant grapevine genotype (D). A, Internal surface view of part of a vessel lateral wall in a PBS buffer-inoculated Chardonnay vine. Intervessel pits with secondary cell walls (sw) in place were transversely elongated and arranged scalariformly. Only part of the intervessel PM (arrows) for each pit could be seen through the pit aperture. B to D, The secondary wall borders of each pit were removed to expose the whole intervessel PM. B, Intervessel PMs in a PBS buffer-inoculated Chardonnay vine. C, Intervessel PMs in a vessel not associated with the bacteria in a Xylella-infected Chardonnay vine. D, Intervessel PMs in a Xylella-infected U0505-01 vine. Bar in each section equals 5 μm.
