Fig. 3From: Rapid diagnostics for Gnomoniopsis smithogilvyi (syn. Gnomoniopsis castaneae) in chestnut nuts: new challenges by using LAMP and real-time PCR methodsVisual detection of LAMP products (V-LAMP) by single-tube colorimetric reaction and electrophoretic gel. Representative visual inspection of Gnomoniopsis smithogilvyi from different plant tissues and mycelium. NTC = No Template Control. The assessment for the V-LAMP assay was based on the HNB color change visualization of the LAMP products (Positive samples = blue color change in reaction; negative samples = purple color reaction)Back to article page
