Fig. 4.

Detection of TRSV using the microarray. The three probes targeting TRSV were nepo_5_848, nepo_5_836 and nepo_5_901, and all hybridized positively to the virus. The array image is a computer generated pseudo-color image. Probes targeting Nepovirus were highlighted with red rectangles. Probes not included in the red rectangles were probes targeting the other virus genera. Some spots targeting the other virus genera were visible on the image, but they were all below the detection threshold, as explained in the Section 2. Some probes targeting Nepovirus were not positive, as can be seen in the lower right rectangle of each image, because they may target the other viruses, other than TRSV, in the genus Nepovirus.
