Abstract

The paper is devoted to elucidation of gene transcription of chloroplast operons in barley plants. Operons which include genes encoding functionally similar proteins, were shown to be transcribed evenly under various physiological conditions. On the contrary, if operons contain genes the products of which participate in differing metabolic pathways or if these products represent components of different functional complexes, they may have differing rates of transcription intensity. This may be explained as the result of the existence of additional pathways regulating posttranscriptional expression of plant plastid operon genes.
