Sequence Analysis of the Internal Transcribed Spacer (ITS) Region of the Nuclear Ribosomal DNA (nrDNA), and trnL Intron of Chloroplast DNA (cpDNA) of the Chrysochamela (Fenzl) Boiss. (Brassicaceae) In Turkey

Abstract

Brassicaceae family is an important one since it includes many economic and significant industrial oilseeds, spices, vegetables and some forage plants. In this study, sequences analysis among Chrysochamela (Brassicaceae) species distributed in Turkey were conducted nrDNA ITS and cpDNA trnL intron sequences. Chrysochamela species were collected and brought to the laboratory. ITS and trnL intron sequences were corrected with BioEdit and FinchTV programs. As a result of the study, ITS nucleotide compound compositions were determined as 22.7% T, 29.1 C, 21.5% A and 26.7% G. The lowest distance was 0.000 and the highest distance was 0.037. The phylogenetic tree obtained using the MEGA 6.0 program consists of two large groups. According to trnL intron sequences 37.9% T, 18.4 C, 28.3% A and 15.5% G. Nucleotide compound compositions were determined. The genetic distance between species was determined between 0.000 and 0.022. Maximum likelihood phylogenetic tree consists of two large groups. As a result, phylogenetic analyzes using ITS and trnL intron sequences were compatible with each other. It was also in past studies found to be supported by morphological, anatomical and RAPD data.
