Creation of glyphosate-resistant Brassica napus L. plants expressing DesC desaturase of cyanobacterium Synechococcus vulcanus
Aim. Creation of glyphosate-resistant canola plants expressing bifunctional hybrid desC::licBM3 gene. In the hybrid gene the sequence of DesC desaturase of cyanobacterium S. vulcanus without plastid targeting was fused with the sequence of thermostable lichenase reporter LicBM3 gene. Methods. Agro...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Aim. Creation of glyphosate-resistant canola plants expressing bifunctional hybrid desC::licBM3 gene. In the
hybrid gene the sequence of DesC desaturase of cyanobacterium S. vulcanus without plastid targeting was fused
with the sequence of thermostable lichenase reporter LicBM3 gene. Methods. Agrobacterium tumefaciensmediated transformation, PCR, quantitative and qualitative determination of lichenase activity, genetic
analysis. Results. Transgenic canola plants, carring the enolpyruvat shikimat phosphate syntase gene (epsps),
conferring on plants resistance to phosphonomethyl glycine herbicides (Roundup), as well as the desC::licBM3
gene, were selected. The presence of transgenes was confimed by multiplex PCR. The epsps gene expression in
canola was shown at the transcription level, during in vitro growth and after greenhouse herbicide treatment.
Activity of the licBM3 gene product as a part of hybrid protein allowed quantitative and qualiative estimation of
the desaturase gene expression. Inheritance of heterologous genes and their expression in the first generation
were investigated. Conclusions. Transgenic canola plants were obtained, the presence of trangenes in plant
genome was proved and expression of the target genes was detected.
