چکیده انگلیسی
A PCR-based method was developed for the stone fruit quarantine pathogen Xanthomonas arboricola pv. pruni (Xap), which provides rapid, sensitive and specific in planta detection and isolate identification. Primers specific for Xap were identified using random amplified polymorphic DNA (RAPD). Simplex PCR with these primers had a limit of detection per PCR reaction of approximately 10Â CFU for isolate cultures and 50Â CFU for plant material when used on tenfold dilutions of isolate culture or genomic DNA extracted from spiked samples, respectively. The primers were adapted as a high-throughput single-step screening based on a digoxigenin-labeled DNA probe assay with a detection limit of 4Â ÃÂ 102Â CFU from isolate cultures. A duplex-PCR method was designed that includes the pathovar-level with species-level primers based on species-specific regions of the quinate metabolic gene qumA, increasing diagnostic confidence and offering the first molecular test for all X. arboricola pathovars.
