摘要:Variation of Diplodia riata , a fungal species associated with botryosphaeria dieback of grapevine, was investigated with respect to its genetic, phenotypic and pathogenic characteristics. The inter-simple quence repeat (ISSR) technique was ud to investigate the genetic diversity of 83 isolates of D.riata . Five ISSR primers were able to provide reproducible and polymorphic DNA fingerprint patterns, thus showing a relevant genetic variability in the species. Analys of ISSR data 海绵宝宝怎么画
by different clustering methods grouped the isolates into two distinct clusters through the Bayesian and DAPC analys. No relationships between either geographic or host origin of isolates and genetic clusters were obrved. Several reprentative isolates from each genetic cluster were chon for studying their conidial dimensions, in
