PCR by hptII - and VirG -specific primers. Putative transformants were screened by PCR. The presence of T-DNA was verified by hptII-specific primers and the possible Agrobacterium contamination was screened by Agrobacterium virG-gene specific primers. MW, molecular weight marker; 0, PCR blank; 1–14, putative transgenic strawberry DNAs; Wt, wild-type strawberry DNA; V, pCAMBIA1391Z vector; At, Agrobacterium DNA.
