Genetic diversity assessment of sesame core collection in China by phenotype and molecular markers and extraction of a mini-core collection

Abstract Background Rosa damascena Mill is a well-known species of the rose family. It is famous for its essential oil content. The aim of the present study was to assess the genetic diversity and population structure of a mini core collection of the Iranian Damask rose germplasm. This involved the use of universal rice primers (URP) and start codon targeted (SCoT) molecular markers. Results Fourteen URP and twelve SCoT primers amplified 268 and 216 loci, with an average of 19.21 and 18.18 polymorphic fragments per primer, respectively. The polymorphic information content for URR and SCoT primers ranged from 0.38 to 0.48 and 0.11 to 0.45, with the resolving power ranging from 8.75 to 13.05 and 9.9 to 14.59, respectively. Clustering was based on neighbor-joining (NJ). The mini core collection contained 40 accessions and was divided into three distinct clusters, centered on both markers and on the combination of data. Conclusion Cluster analysis and principal coordinate analysis were consistent with genetic relationships derived by STRUCTURE analysis. The findings showed that patterns of grouping did not correlate with geographical origin. Both molecular markers demonstrated that the accessions were not genetically diverse as expected, thereby highlighting the possibility that gene flow occurred between populations.

Luffa Aegyptiaca

Luffa aegyptiaca is a popular climbing herb endemic in Egypt. We studied the genetic diversity among ten Luffa landraces (Cairo, Beni Suef, Menoufiya, Damietta, Banha, Aswan, Kafr el?Sheikh, Bir el?Abd, MarsaMatruh and Asyut) collected from different districts in Egypt. The results obtained from DNA fingerprinting revealed that there were polymorphic loci with average percentage of 44.6 among collected landraces whereas polymorphic loci obtained from SDS?PAGE were 23%. Discrimination between landraces was more efficient by using RAPD?PCR marker than total proteins SDS?PAGE which showed a limited level of intraspecific diversity.Plant Tissue Cult. & Biotech. 26(2): 209-217, 2016 (December)
