Additional file 1: Figure S1. of Pollen-mediated gene flow from transgenic to non-transgenic switchgrass (Panicum virgatum L.) in the field

Southern blot analysis of T0 transgenic switchgrass events containing stable integration of the T-DNA. Blot was probed with 32P-labeled pporRFP gene fragment. Lanes labeled with ‘2BR’ contain transgenic line genomic DNA samples, lane ‘ST1 control” is the nontransgenic control genomic DNA sample, lane ‘2BR plasmid’ contains the plasmid positive control. Genomic DNA was digested BamHI genomic DNA (10 μg) from each plant sample. (PDF 46 kb)
