“…The interspecific genetic similarity was in agreement with that found based on ISSR markers [3] and with the first classification made by [10] in which C. incisa and C. angustifolia belong to section Incisae and C. incana belongs to section Incanae. Genetic similarity calculated for each pair of populations varied from 0.801 to 0.98.…”

“…The highest similarity value between populations was detected for the comparison between Fazenda Souza and Conceição da Linha Feijó populations (0.98), both of which are located at Caxias do Sul region and separated each other by 20 km. High genetic similarity within other Cunila species were previously reported using RAPD [11] and ISSR markers [3,12,13]. Following those authors, the high similarity found may be associated to restricted genetic bases reflecting founder effect and low gene flow among populations.…”

“…Based on growth habit and inflorescence morphology, Epling (1936) classified the South American species into three sections: Incanae, Incisae and Spicatae. Recently, studies started to address the taxonomical review of Cunila, indicating only two sections recognized for this genus: Spicatae and Incanae/Incisae [3].…”

Cunila incisa is a perennial shrub with 1-2 m high with ramified branches. This highly aromatic species is commonly used in south brazilian folk medicine, growing wild at the margins of the forest in the highlands. Based on the medicinal and aromatic potential of this species the aim of this survey was to examine the genetic variation within and among populations. In this context, 13 C. incisa populations collected in Rio Grande do Sul, Brazil, were analyzed by RAPD. Cluster analysis afforded to discriminate populations under three groups. The C. incisa populations presented low intrapopulational variability, indicating that the populations form distinct genetic pools possible due to founder effects and low interpopulation gene flow.

“…The high polymorphism rates (88%) found in UBC-810 and other ISSR primers in this study indicated that molecular characterization of genotypes using ISSR markers is an efficient strategy. This level of polymorphism is similar to results found in previous studies (Agostini et al, 2008;Trindade et al, 2008Agostini et al, 2010. Júnior et al (2011) identified a range of polymorphic alleles between 4-11, which was lower than that observed in the present study.…”

ABSTRACT. Genetic diversity in crops is essential to make improvements related to superior germplasms. Implementation of molecular markers to identify suitable genotypes speeds up the breeding progress by enhancing selection efficiency. This study was carried out to probe genetic diversity among 21 maize genotypes using 20 inter simple sequence repeat (ISSR) markers. We identified a total of 190 polymorphic bands with an average of 9.5 alleles per primer. The highest number of polymorphic bands (17) was found using ISSR marker UBC-10, whereas the lowest number of polymorphic bands (4) was found using UBC-809. The coefficient of genetic similarity ranged from 0.888 to 0.118%. The highest similarity was found between accessions 12 (015224) and 9 (015114), whereas the lowest similarity was found between genotypes 20 (EV-5098) and 14 (015030). The polymorphism information content ranged from 0.17 to 0.47. A dendrogram was generated based on Jaccard's distance matrix. The genotypes were found to group into two major clusters that could be further partitioned into two sub-clusters. Genotypes located within the same cluster are genetically more closely related to each other. The present study efficiently identified diverse genotypes that may be used for creating new varieties with distinct characteristics. The identified genotypes could be used as parents for future development of diverse populations.

“…In recent years, the use of molecular markers to evaluate genetic variability has become an important tool in the study of populations of various plant species, including several aromatic and medicinal plants (Fracaro and Echeverrigaray 2006;Guo et al 2006;Liu et al 2006;Agostini et al 2008;Sarwat et al 2008). These researchers considered the urgent need to integrate the information resulting from genetic studies with ecological data in order to formulate efficient conservation strategies.…”

Thymus daenensis is an aromatic medicinal plant endemic to Iran. We used inter simple sequence repeat (ISSR) markers to detect genetic polymorphism in this herb using 17 T. daenensis accessions collected from different geographic regions in Iran. The 15 primers chosen for analysis revealed 256 bands, of which 228 (88.9%) were polymorphic. Jaccard's similarity indices based on ISSR profiles were subjected to UPGMA cluster analysis. The generated dendrogram revealed two major groups. The Tc group included the accessions collected from the center of the Zagros Mountains, and the Te group was collected from the extremes of the Zagros range. A principal coordinate analysis confirmed the results of clustering. The results showed that the divergence of accessions based on the Zagros Mountains is more logical in comparison with classification on the basis of provincial borders. Gene diversity and expected heterozygosity were greater in the Tc group than in the Te group, suggesting that the germplasm collected from the center of the Zagros Mountains is more variable.
