Fig. 4From: In situ hybridization for the detection of rust fungi in paraffin embedded plant tissue sectionsImages of C. × morifolium samples infected with P. horiana and prepared by ISH (Red scale bar = 100 μm). Photos are organized so that columns represent the probe used for hybridization (indicated by column names) and rows represent sample tissue type and post-hybridization wash temperature (indicated by row names). Purple staining of the tissue indicates hybridization signal generated by HRP reacting with purple substrateBack to article page
