From: Detection of white head symptoms of panicle blast caused by Pyricularia oryzae using cut-flower dye
Lesions with lines of necrosis appeared from 5 DPI. Leaves were treated with water (NS, no staining) or dyed with red or blue cut-flower dye. Upper row: the lower (abaxial) side of the leaf blades is shown. The region between the two black arrowheads in each upper image is an example of a necrosis line. Middle row: cross-sections observed by light microscopy. Lower row: cross-sections observed by fluorescence microscopy. White arrowheads indicate hyphae detected with fluorescent wheat germ agglutinin conjugate. White bars, 2000 µm; black bars, 100 µm
