Molecular systematic study of Levl. (Brassicaceae) using internal transcribed spacer sequence of nuclear ribosomal DNA (ITS) and chloroplast L and L-F sequences.

The internal transcribed spacer (ITS) region of nuclear ribosomal DNA, L and L-F genes of Levl. (family Brassicaceae) were sequenced and analyzed with the sequence of related species retrieved from NCBI GenBank to detect pattern of evolutionary differentiation. All trees resulting from combined sequence analyses data of ITS, L and L-F gene resolve that - an endemic species to South Korea clade with (100% bootstrap support). The evolutionary history was inferred using the Maximum Parsimony method. The consistency index is (0.588235), the retention index is (0.687500), and the composite index is 0.519622 (0.404412) for all sites and parsimony-informative sites (in parentheses). The result of the analysis using Maximum Parsimony was found congruence with Maximum Likelihood method and in Baseyan analysis.
