“…To test the hypothesis of isolation by distance, the correlation between pairwise geographic and Nei's genetic distances was tested for all natural populations by using the Mantel test with 3000 permutations (Mantel, 1967). In addition, the computation of the Spearman rank correlation between RAPD gene diversity (H E ) values obtained in this study and ISSR H E values obtained previously (Ma et al, 2008) was carried out with SAS 8.0.…”

“…A highly significant (P < 0.001) genetic difference was found between groups, between populations, and within populations. Spearman's rank correlation between the genetic diversity (H E ) values produced by random amplified polymorphic DNA (RAPD) analysis from this study and inter-simple sequence repet (ISSR) analysis from previous study (Ma et al, 2008).…”

“…By contrast, genetic diversity was lowest in population POP5, with PPB = 46.49%, N E = 1.281, H E = 0.159, I = 0.173, and H B = 0.213 (Table 3). ISSR analysis had been previously performed on these populations (Ma et al, 2008) and used in this study. Consequently, the genetic diversity profiles obtained in this study with RAPD markers can be compared with those obtained previously with ISSR markers.…”

“…The objectives of the present study were 1) to investigate the level of RAPD variation in eight natural populations of E. sibiricus in southeast Qinghai-Tibet Plateau, 2) to quantify the genetic diversity within and between natural E. sibiricus populations (such information can also serve as a guide to preserving the genetic resources of this ecologi-cally important species), and 3) to examine the consistency of results from RAPD and ISSR variation previously carried out in E. sibiricus (Ma et al, 2008).…”

ABSTRACT. Genetic diversity of Elymus sibiricus (Poaceae) was examined in eight populations from the southeast Qinghai-Tibet Plateau. We detected 291 RAPD polymorphic loci in 93 samples. The percentage of polymorphic bands (PPB) was 79%. Genetic diversity (H E ) was 0.264, effective number of alleles (N E ) was populations per generation (N m ) was 1.06. The populations were found to share high levels of genetic identity. No significant correlation was found between geographic distance and pairwise genetic distance (r = 0.7539, P = 0.9996). Correlation analysis revealed a significant correlation (r = 0.762) between RAPD H E found in this study and ISSR H E values from a previous study.

“…For example, a number of studies have been conducted on the genetic diversity of E. caninus [25,26], E. fibrosus [27][28][29], E. alaskanus [30][31][32][33], E. trachycaulus [34,35], and E. sibiricus [36,37]. These studies have shown that each species possesses a unique pattern of genetic variability, and they are useful for understanding the genetic diversity for similar outcrossing grass species.…”

Recent advances in next generation sequencing technologies make genotyping-by-sequencing (GBS) more feasible for the molecular characterization of plant germplasm with complex and unsequenced genomes. This study represents the first preliminary effort using GBS to discover genome-wide genetic variants of northern wheatgrass (Elymus lanceolatus ssp. lanceolatus (Scribn. and J. G. Sm.) Gould) plants and to assess the genetic diversity present in four cultivated and six wild accessions. The effort generated the first novel set of genomic resources and 5659 single nucleotide polymorphism (SNP) markers for this tetraploid grass. The diversity analysis revealed 8.8% of SNP variation residing among the 10 accessions and 1.9% SNP variation present between cultivated and wild accessions. The Bayesian analysis identified three major clusters of the assayed samples, and the principal coordinates analysis revealed the genetic distinctness of the two accessions collected from Nevada and Wyoming. The flow cytometry analysis confirmed the tetraploid nature of some of the assayed samples and estimated the average genome size to be 9.3-9.4 Gb for this species. These findings are useful for the genetic improvement of this native grass species for forage production and rangeland reclamation. The findings are also encouraging for the broad application of genotyping-by-sequencing in the characterization of genome-wide genetic variability in non-model polyploid plants.

Population genetics of Mesembryanthemum crystallinum in Egypt

Genetic diversity plays an important role in any long term management planning of a species. Mesembryanthemum crystallinum has been naturalized in disturbed regions along the Mediterranean coast competing with native plants. The levels and pattern of the genetic variation within and among its populations along Deltaic Mediterranean coast of Egypt was investigated using random amplified polymorphic DNA (RAPD). Forty‐two samples representing nine populations of M. crystallinum were collected. The results showed that %PPB values for a single population ranged from 9.14% to 28.91% with an average of 19.76%. The average of Shannon information index (SI), expected heterozygosity (He) and unbiased expected heterozygosity (uHe) values were 0.098, 0.064 and 0.072, respectively. According to AMOVA analysis, 9% of the total genetic structure was attributable to regional divergences and 38% to population differentiation within regions and 53% differences among individuals within populations. Mantel test showed a low correlation (r2= 0.001) between the studied populations. The dendrogram exhibited two clusters of populations which were confirmed by principal coordinate analysis (PCoA). The study concluded that M. crystallinum has lower levels of diversity than other plant species with similar life history characteristics and high genetic differentiation among population.
