Fig. 2From: Loop-mediated isothermal amplification: a rapid molecular technique for early diagnosis of Pseudomonas syringae pv. syringae of stone fruitsThe results of syrD gene PCR amplification. Lanes 1 and 6, 1kB DNA ladder (Fermentas); lane 2, blank; lane 3, negative control (Xanthomonas ssp); lanes 4 and 5 show positive responses. A 1 kb molecular weight ladder was used, and all products were stained with SYBR GoldBack to article page
