| Abstract: | Nucleotide sequences of b/c intron of the mitochondrial gene nad1 were determined for the first time and analyzed in 24 plants of Monotropa hypopitys and in three related Ericaceae species. Two mitotypes of b/c intron of the nad1 gene, differing in sequence lengths and the presence of a number of single nucleotide substitutions and indels, were revealed in M. hypopitys. For the first time, a possible pre-mRNA secondary structure of M. hypopitys b/c intron was determined and IBS/EBS binding sites and the borders of six functional domains were identified. |
