Figure 1From: A novel method for efficient and abundant production of Phytophthora brassicaezoospores on Brussels sprout leaf discsCompatible interaction between the Brussels sprouts cultivar Cyrus and P. brassicae. P. brassicae infects leaves, stems and roots of Brussels sprouts cultivar Cyrus. Lesion development on the adaxial side of a leaf 4 days post inoculation (dpi) with isolate CBS686.95 (A). Stem lesions 4 dpi with, from left to right, isolates CBS686.95, HH and GFP transformant 155m (C). Root infection 4 dpi with isolate HH (E). Mycelial structures visualized by GFP fluorescence in leaf (B), stem (D) and root (F) tissue, 5 dpi with GFP transformant 155m. Hyphal protrusions are indicated by arrows. Scale bars represent 100 μm (B, D) and 10 μm (F).Back to article page
