Fig. 2From: Rpv3–1 mediated resistance to grapevine downy mildew is associated with specific host transcriptional responses and the accumulation of stilbenesComparison of Plasmopara viticola development in leaves of a susceptible and Rpv3–1 cultivar. Time course of P. viticola development was evaluated using UV epifluorescence after aniline blue staining at 24 hpi (top), 48 hpi (middle) and 72hpi (bottom). Development of the avirulent (avrRpv3+) P. viticola isolate on leaf discs of the susceptible cultivar (a, e, i) and on Rpv3–1 locus containing cultivar (b, f, j) and development of virulent (avrRpv3ˉ) P. viticola isolate on leaf discs of the susceptible grapevine cultivar (c, g, k) and on Rpv3–1 locus containing cultivar (d, h, l) are shown. Arrows indicate sporangiophores. Images are representative of three biological replicates. Scale bars correspond to 100 μmBack to article page
