Introduction

This integrative locus NSI right arm of Synechococcus elongatus genome comes from the plasmid pAM4951 (Taton et al. 2014). This part is flanking the insert in 3', and must be used with the integrative locus (BBa_K3930028) NSI left arm part in 5'.

Results

Integration of part (BBa_K3930026) into the cyanobacterium genome

The part (BBa_K3930026) was transformed into the S.elongatus UTEX 2973 following the triparental conjugation protocol of Gale et al. (2019). The construction is flanked by parts (BBa_K3930027) and (BBa_K3930028). Figure 1 shows the electrophoresis gel of colony PCR to verify integrants genotype.



Figure 1: Integration of pCONCOMBRE insert in the cyanobacterium genome

pCONCOMBRE insert integration was checked by PCR visualised on EtBr stained agarose electrophoresis gel. A theoretical gel is presented on the right (note that a different ladder is presented on the theoretical gel). Most expected sizes were obtained, but one amplicon for the left arm (LA) had not the right size. However, all genes from the insert were detected.


We concluded that the integrative locus NSI right arm (BBa_K3930027) coupled with the integrative locus (BBa_K3930028) NSI left arm part is nonetheless functional under these experimental conditions.
