From: Detection of white head symptoms of panicle blast caused by Pyricularia oryzae using cut-flower dye
Panicle branches damaged by rice blast fungus were dyed with red or blue cut-flower dye. Left panels: the border of the dyed tissues was cut in cross-section (arrowheads); central panels: light microscopy images; right panels: fluorescence microscopy images (fluorescent wheat germ agglutinin conjugate). Upper panels: high hyphal density; lower panels: low hyphal density. White arrowheads in fluorescent images indicate hyphae detected in vascular bundles. White bars, 2000 µm; black bars, 100 µm
