Polymorphism of the chloroplast gene rps2 in parasitic plant Monotropa hypopitys L. from the European Russian populations

Abstract

The complete nucleotide sequence of the chloroplast rps2 gene is determined and the polymorphism of this gene in 26 Monotropa hypopitys accessions from the populations of the European part of Russia is analyzed. The studied accessions can be divided into two groups on the basis of the rps2 gene length. In the first group, the rps2 gene sequence length is 711 bp, and in the second group, it is 753 bp. Also, the groups differ from each other by 42 SNPs, which lead to 11 radical and 15 conservative amino acid substitutions in the amino acid sequence of the protein. They also differ in the position of regulatory elements in the 5'-untranslated region of the gene.
