“…Polyprobes have been applied successfully for the detection of an array of combinations of plant viruses and/or viroids affecting different crops ( Table 1 ). Polyprobes have been developed and used to detect four viroids affecting citrus trees ( Cohen et al, 2006 ), the six main viruses infecting tomato ( Aparicio et al, 2009 ), six viruses affecting pome and stone fruits ( Lin et al, 2011 ), four viroids affecting grapevine ( Zhang et al, 2012 ), eight viroids affecting ornamentals and vegetables ( Torchetti et al, 2012 ), eight viroids infecting coleus plants ( Jiang et al, 2013 ), and four viruses of apple and pear trees ( Fajardo and Nickel, 2014 ). Remarkably, this technology has great potential for simultaneous multipathogen detection.…”
