Contribution of consensus 5'-untranslated region to the translational efficiency of heterologous genes in plant cells

The results of bioinformatics analysis allowed to reveal the following consistent pattern: the average length of the 5'-untranslated region (5'-UTRs) for most A. thaliana's genes with high expression levels range from 80 to 120 bp, with an average GC content of 36,5%. Based on alignment results was defined motive in 5'-UTRs, as a new regulatory element, which could potentially provide highly efficient expression and synthesis of the target product in plants. This sequence has a length of 87 bp and GC content of 35.6%. It was demonstrated that consensus sequence of 5'-UTRs increased accumulation of the bi-reporter protein more than 25%, by that acting as a potential positive regulatory element on translational efficiency.
