Cloning of homologous targeting sequences and construction of antibiotic-freeplastid site-specific integration expression vector of chicory

Abstract

Abstract: A pair of primers used in amplifying plastid fragments of chicory was designed based on the conservative sequences of both rps7 and 16S rDNA genes in the tobacco, maize, Arabidopsis thaliana and soybean plastid genomes. The 4.8 kb fragment was cloned from the chicory plastid genome. Sequencing analysis indicated that this fragment was 4751 bp in size (GenBank Accession Number GQ199478), and consisted of 449 bp 5′-end of the rps7 gene, 793 bp sequence of rps12 gene, 72 bp sequence of the trnV gene, 1 315 bp 5′-end of the 16S rDNA gene and most gene intergenic regions. The BLAST results showed that the similarity of this fragment with tobacco and lettuce were 92% and 97% respectively. Using this fragment as a homologous targeting sequence, we constructed the site-specific integration chicory-specific plastid expression vector pJBADH-GFP that carries the multicistron expression cassette of prrn-BADH-gfp-psbA-3′. The results of restriction analysis and PCR detection confirmed this. This plastid expression vector is desirable both for use in establishment of a chicory antibiotic-free plastid transformation system and traits improvement of chicory or for use as a bioreactor to produce edible vaccines for animals via plastid genetic transformation.
