In-the-Field Authentication of Grapevine (Vitis vinifera L.) cv: Albariño Using Chlorotype Discrimination and a Single SNP Interrogation by LAMP

Figure 8

LAMP-based test that simultaneously interrogates the presence of a specific chlorotype (A-open circles- or D-open triangles-) and the genotype at the SNP 191_100 (C allele (filled circles) or T allele (filled squares)) for the “Albariño” (yellow colour) and “Treixadura” (green colour) varieties. Positive reactions are detected between 15 and 35 mins (time-to-read). The negative NTC controls are not visible behind the points with a lack of fluorescence signal. Two replicas of each cultivar were used.
