Red amaranth Amaranthus cruentus is a valuable fodder and grain crop. To generate new varieties of this plant, genetic transformation methods can be used, but for A. cruentus such methods remain undeveloped. This article is devoted to the description of the results of our work at agrobacterial transformation of epicotyl segments of Amaranthus cruentus by ARGOS-LIKE transgen of Arabidopsis thaliana controlled by 35S promoter. In the results 3 transgenic amaranth plants with the genetic engineering structure 35S::ARGOS-LIKE were generated. The amaranth plants transgenicity were confirmed by the PCR analysis for the presence of marker and target genes. Two transgenic plants were acclimatized to soil and open air conditions.
