Description
Summary:In this study, intra-specific variations in naturally growing and cultivated mastic tree (Pistacia lentiscus L.) samples obtained from western parts of Turkey were examined using ISSR and IRAP marker techniques. Samples from Crete and Chios were also included in the study. Morphological measurements of some leaf characteristics of the samples were performed and the measured data was evaluated statistically with a Pearson Correlation analysis to reveal the correlations between character pairs. ISSR primers produced 81 bands between 161-1884bp with 96.3% polymorphism and IRAP primers produced 72 bands between 124-2027bp with 91.67% polymorphism. Polymorphism information content (PIC) values were 0.458 and 0.418 for ISSR and IRAP, respectively. Genetic similarity matrix was examined with Jaccard’s coefficient. Maximum similarity was found between the Cretan samples (LG2 and LG3) with the ISSR analysis (0.933) and between L25A (C1, Bodrum) and L29A (C1, Milas) with the IRAP analysis (0.593). Unweighted pair group method with arithmetic mean (UPGMA) dendrogram was divided into 12 and 4 groups by ISSR and IRAP methods, respectively. Specimens were segregated on 3 main different clusters by the Principal Component Analysis (PCA) based on the combined marker systems. The results showed that P. lentiscus has very high ratios of intraspecific variation. The present work is an original study in terms of large sampling including wild genotypes, cultivated specimen, Chios and Cretan varieties, use of ISSR and IRAP combination, determination of relations between culture and wild genotypes and the use of Bagy-1 retrotransposons in intraspecific polymorphism. This study may be considered as a reference study for studies on gene pools of P. lentiscus and phylogenetic relationships within the species and may contribute to species concept and agricultural breeding programs.
