Molecular Genetic Diversity of Prunus armeniaca L. (Rosaceae) Genotypes by RAPD, ISSR-PCR, and Chloroplast DNA (cpDNA) trnL-F Sequences

Abstract

In this study, phylogenetic analysis of some Turkish Prunus armeniaca L. genotypes was conducted based on RAPD-PCR, ISSR-PCR, and chloroplast DNA (trnL-F) sequence analyses. Prunus armeniaca genotypes were obtained from Malatya province, and brought to the laboratory for genomic DNA isolation. Eleven RAPD and fifteen ISSR primers were used to determine molecular characterization of Prunus armeniaca genotypes. For the amplification of the trnL-F region, trne and trnf primers were used in Polymerase Chain Reaction (PCR). A total of 46 and 95 bands were obtained with RAPD and ISSR analysis, respectively. The trnL-F sequences varied from 398 to 403 nucleotides. Average nucleotide composition of trnL-F sequences was 31.0% T, 14.4% C, 37.4% A and 17.2% G. The genetic distance between the five apricot genotypes is 0.00. A maximum likelihood tree was generated to determine genetic relationships among Prunus armeniaca genotypes. Analysis of Prunus armeniaca genotypes based on RAPD, ISSR, and trnL-F sequences revealed that the rate of polymorphism obtained using RAPD and ISSR were higher than those obtained through the trnL-F sequences.
