molecular diversity within and between ajowan (carum copticum l.) populations based on inter simple sequence repeat (issr) markers

چکیده
study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. in the present study, genetic diversity among and within 15 iranian native ajowan(carum copticum l.) populations were determined using inter simple sequence repeat (issr) markers. twelve selected primers produced 153 discernible bands, with 93 (60.78%) being polymorphic, indicating considerable genetic diversity at the population level. number of polymorphic bands per primer ranged from 4 to 11 with an average of 7.75. the largest percentage of polymorphic loci was 78.57% for primer ubc818. based on an un-weighted pair-group method using arithmetic average (upgma) clustering algorithm, four distinct groups were established. results of the principal coordinate analysis (pcoa) corresponded to those obtained through cluster analysis. analysis of molecular variance (amova) showed that the genetic variation was found mainly within populations (61%), but variance among populations was only 39%. this study has detected significant genetic differentiation among c. copticum populations. the current study confirmed the importance of molecular studies in detecting genetic variation among genotypes in selecting diverse parents to carry out crossing program successfully.

متن کاملGenetic diversity analysis of okra (Abelmoschus esculentus L.) by inter-simple sequence repeat (ISSR) markers.
Okra (Abelmoschus esculentus L.) is not only a nutrient-rich vegetable but also an important medicinal herb. Inter-simple sequence repeat (ISSR) markers were employed to investigate the genetic diversity and differentiation of 24 okra genotypes. In this study, the PCR products were separated by electrophoresis on 8% nondenaturing polyacrylamide gel and visualized by silver staining. The 22 ISSR...
متن کاملMaize (Zea mays L.) Genotypes Diversity Study by Utilization of Inter-Simple Sequence Repeat (ISSR) Markers
Analysis of the extent and distribution of genetic diversity in crop plants is essential for optimizing sampling and breeding strategies. Several methods were identified for the existence of diversity in maize for the aim of perfect selection based on great diversity among maize genotypes. In this study, Inter-simple sequence repeat (ISSR) markers were used to assess genetic diversity in a sele...

متن کاملMolecular Characterization of Cultivated Bromeliad Accessions with Inter-Simple Sequence Repeat (ISSR) Markers
Bromeliads are of great economic importance in flower production; however little information is available with respect to genetic characterization of cultivated bromeliads thus far. In the present study, a selection of cultivated bromeliads was characterized via inter-simple sequence repeat (ISSR) markers with an emphasis on genetic diversity and population structure. Twelve ISSR primers produc...
