Genetic constructs creation using Golden Gate cloning method

Abstract

Aim. Creation of genetic constructions to study the effects of various regulatory elements, namely promoters, on the expression of GFP reporter protein. Methods. For creation genetic constructs, the method of molecular cloning Golden Gate was used, which allows the rapid creation of genetic vectors using IIS type restriction enzymes and T4 DNA liga-ses. Results. For research six different promoters were selected, namely the 35S CaMV (Cauliflower Mosaic Virus), double 35S CaMV promoter, promoters of the RbcS2B and RbcS1B genes encoding a small subunit of ribulozobisphosphate carboxylase (RuBisCo) isolated from Arabidopsis thaliana (L.) Heynh.; promoters of genes encoding chlorophyll a-b binding proteins (LHB1B1 and LHB1B2) also isolated from A. thaliana (L.) Heynh. All transcription units additionally contained the following elements: the 5'-untranslated region Ω sequence (5’UTR Ω) from the tobacco mosaic virus TMV (Tobacco Mosaic Virus); the coding sequence of the gene gfp (Green Fluorescent Protein) isolated from A. victoria and the 35S Terminator CaMV with the polyadenylation signal and the 3'-untranslated region sequence. As a result, six genetic constructs with different regulatory elements, namely promoters, have been created. Conclusions. To study the effects of various regulatory elements, namely promoters, on the expression of a GFP repor-ter protein in transient or stable genetic transformation of plants the created genetic constructs can be used.Keywords: cloning, genetic constructs, promoters, Green Fluorescent Protein (GFP).
