Chloroplast DNA trnL-trnF spacer sequences of tRNA genes of 14 specimens of the fam. Lemnaceae have been characterized. Nucleotide polymorphism analysis of the spacer trnL-trnF of geographically isolated and morphologically differing accessions of S. polyrrhiza that is the most widespread species of Spirodela genus showed the low level of intraspecific variability. Five trnL-trnF haplotypes of S. polyrrhiza are identified. Both mono-, and polynucleotide repeats, and also extensive indels, specific to representatives Spirodela polyrrhiza, Landoltia punctata and Lemna sp. are revealed. Competency of Landoltia genus allocation as separate entity was confirmed. |
