Genomic location of foreign genes. Quantitative polymerase chain reaction was used to amplify five loci of known genomic origin [plastid rbcL (light green) and trnL/trnF (dark green), mitochondrial atp1 (light pink) and matR (dark pink) and nuclear phyA (maroon)] and three foreign genes of uncertain provenance [atp1 (light blue), atp6 (medium blue) and matR (dark blue)]. All eight reactions were run in duplicate using as templates, either total genomic DNA (A), mitochondrial-enriched DNA (B) or plastid-enriched DNA (C) isolated from Plantago coronopus line C.
