ABSTRACT
A set of module vectors for stable or transient gene expression in plants was constructed with regard to the majority of factors ensuring efficient heterologous gene expression in plants. The vectors are convenient to clone new regulatory elements and genes of interest via simple molecular cloning procedures. The vectors can be used to obtain transgenic plants with stable heterologous gene expression as well as to achieve transient expression because one vector includes the gene for the tomato bushy stunt virus p19 protein, which acts as a suppressor of posttranscriptional gene silencing.

The basic methods used in current practice for stable and transient expression of heterologous genes in plants are presented and compared. The key areas of research in the heterologous expression of genes in plants have been identified by analyzing literature and experimental data: modeling of metabolic pathways; creation of marker-free transgenic plants; the search for new regulatory elements and plant genes influencing the efficiency of expression of heterologous genes in plants; development of new methods for analyzing of transgenic plants and new approaches to the expression of heterologous genes in plants.
