Stable site-specific integration and expression of uidA under the rice psbA promoter with different start codons in tobacco chloroplasts. Southern hybridization of genomic DNA using uidA (A) and partial rbcL:accD (B) gene sequences to show the site-specific integration of transgenes into tobacco plastome. Northern hybridization showing the transcription of chimeric uidA in four different transplastomic plants (C) and the blot probed with 16S rRNA to show equal loading of total RNA (D).
