Hypericum Species

Genus Hypericum (Guttiferae, Hypericoideae) is perennial, belonging to the Hypericaceae family, having 484 species in forms of trees, shrubs, and herbs, distributed in 36 taxonomic sections. No detailed Random Amplified Polymorphic DNA (RAPD) studies were conducted to study Hypericum genetic diversity. Therefore, we collected and analyzed six species from five provinces of Iran regions. Overall, seventy plant specimens were collected. Our aims were 1) to assess genetic diversity among Hypericum species 2) is there a correlation between species genetic and geographical distance? 3) Genetic structure of populations and taxa. We showed significant differences in quantitative morphological characters in plant species. H. dogonbadanicum depicted unbiased expected heterozygosity (UHe) in the range of 0.10. Shannon information was high (0.32) in H. perforaturm. H. dogonbadanicum showed the lowest value, 0.17. The observed number of alleles (Na) ranged from 0.22 to 0.53 in H. dogonbadanicum and H. elongaturn. Gene flow (Nm) was relatively low (0.87) in Hypericum. The Mantel test showed correlation (r = 0.45, p=0.0001) between genetic and geographical distances. We reported high genetic diversity, which clearly shows the Hypericum species can adapt to changing environments since high genetic diversity is linked to species adaptability. Present results highlighted the utility of RAPD markers and morphometry methods to investigate genetic diversity in Hypericum species.

Members of Lonicera are characterized by opposite, narrowly elliptic to obovate leaves, white, yellow, reddish, or purple-red corolla with capitate stigma and undulate calyx margin. In Flora Iranica, Wendelbo (1965) classified 19 species of the Lonicera into two subgenera (Chamaecerasus and Lonicera) and three sections, namely Isoxylosteum, Isika and Coeloxylosteum. The four studied species belong to subgenus Chamaecerasus and sections Isika and Coeloxylosteum. No detailed Random Amplified Polymorphic DNA (RAPD) studies were conducted to study Lonicera genetic diversity. Therefore, we collected and analyzed three species from 2 provinces regions. Overall, 45 plant specimens were collected. Our aims were 1) to assess genetic diversity among Lonicera species 2) is there a correlation between species genetic and geographical distance? 3) Genetic structure of populations and taxa. We showed significant differences in quantitative morphological characters in plant species. The Mantel test showed correlation (r=0.66, p=0.0001) between genetic and geographical distances. We reported high genetic diversity, which clearly shows the Lonicera species can adapt to changing environments since high genetic diversity is linked to species adaptability. Present results highlighted the utility of RAPD markers and morphometry methods to investigate genetic diversity in Lonicera species.

Assessing the genetic diversity in the population is the prerequisite to start and develop plant breeding projects. Pistacia vera is considered as a commercial species of Pistacia genus. In Iran, Pistachio export is in the second place in terms of non-oil exports and in the first place among horticultural crops. Therefore, we collected and analyzed 11 pistachio genotype (Pistacia vera), from two provinces of Iran regions. Our aims were 1) to assess genetic diversity among some of Irainian pistachio cultivars 2) is there a correlation between species genetic and geographical distance? 3) Genetic structure of populations and taxa. We showed significant differences in quantitative morphological characters in plant species. Akbari cultivars depicted unbiased expected heterozygosity (UHe) in the range of 0.028. Shannon information was high (0.49) in Seifadini cultivars. Akbari cultivars howed the lowest value, 0.029. The observed number of alleles (Na) ranged from 0.261 to 2.700 in Shahpasand cultivars and Kalehghoochi cultivars. The effective number of alleles (Ne) was in the range of 1.021-1.800 for Akbari cultivars and Moosaabadi cultivars .Gene flow (Nm) was relatively low (0.38) in pistachio cultivars. The Mantel test showed correlation (r = 0.33, p=0.0001) between genetic and geographical distances. We reported high genetic diversity, which clearly shows the among some of Irainian pistachio cultivars can adapt to changing environments since high genetic diversity is linked to species adaptability. Present results highlighted the utility of RAPD markers and morphometry methods to investigate genetic diversity in pistachio cultivars.

High Genetic Diversity

Genetic diversity studies are essential to understand the conservation and management of plant resources in any environment. The genus Consolida (DC.) Gray (Ranuculaceae) belongs to tribe Delphinieae. It comprises approximately 52 species, including the members of the genus Aconitella Spach. No detailed Random Amplified Polymorphic DNA (RAPD) studies were conducted to study Consolida genetic diversity. Therefore, we collected and analyzed 19 species from 12 provinces of regions. Overall, one hundred and twenty-seven plant specimens were collected. We showed significant differences in quantitative morphological characters in plant species. Unweighted pair group method with arithmetic mean and principal component analysis (PCA) divided Consolida species into two groups. All primers produced polymorphic amplicons though the extent of polymorphism varied with each primer. The primer OPA-06 was found to be most powerful and efficient as it generated a total of 24 bands of which 24 were polymorphic. The Mantel test showed correlation (r = 0.34, p=0.0002) between genetic and geographical distances. We reported high genetic diversity, which clearly shows the Consolida species can adapt to changing environments since high genetic diversity is linked to species adaptability. Present results highlighted the utility of RAPD markers and morphometry methods to investigate genetic diversity in Consolida species. Our aims were 1) to assess genetic diversity among Consolida species 2) is there a correlation between species genetic and geographical distance? 3) Genetic structure of populations and taxa.

Impressive Result

Segara Anakan areas can be divided into three different regions according to their salinity. Salinity differences suggested that Commerson’s anchovy population in that area can be divided into three subpopulations due to genetic differences. Genetic differences among subpopulation can be assessed through a population genetic study using random amplified polymorphic DNA. This study aims to evaluate the genetic variation and differences of Commerson's anchovy (Stolephorus commersonnii) collected at three different water salinities in Segara Anakan estuary Cilacap Indonesia. Total genomic DNA was isolated using the Chelex method. Genetic diversity and differences were assessed using RAPD markers and were analyzed statistically using an analysis of molecular variance, as implemented in Arlequin software.  The results showed that high genetic diversity was observed within the subpopulations. However, no significant genetic differences were observed among subpopulations which indicate genetic similarity. A high number of offspring are likely to cause high genetic variation within subpopulations.  Adult and larvae migration is the cause of genetics similarity across Segara Anakan. Another impressive result is that water salinity did not affect the genetic characteristic of Commerson,s anchovy. Genetic similarity of Commerson’s anchovy indicates that Segara Anakan forms a single genetic conservation unit.

The genetic diversity and the relatedness among thirty-one germplasm lines of yellow sarson collected from eastern UP were evaluated using morphological characters and Random Amplified Polymorphic DNA (RAPD) markers. Molecular parameters, viz. A total number of bands, average polymorphic band, average percent polymorphism, average polymorphic information content (PIC), Jaccard’s similarity coefficient, Principal Coordinate Analysis (PCA) and dendrogram generated using RAPD markers. A total of 148 different polymorphic amplification products were obtained using 10 selected decamer primers. The Jaccard similarity coefficient ranged from 0.557-0.899. Maximum polymorphism detected was 100 %.The range of amplification was from 190bp to 9 kb. Some unique bands were also reported with different primers that can be used for the identification of particular accession. PYSC-11-11 and PYSC-11-36 genotypes showed a maximum number of unique loci of different size. 31 germplasm lines grouped into two major clusters I and II based on RAPD profiling. Morphological characterization was done on the basis of leaf, petal and beak characteristics. The similarity value among the germplasm lines ranged from 0.222 to 1.000 using morphological descriptors. The dendrogram generated grouped the germplasm accession into two major groups at 44% similarity value. The cluster analysis was comparable up to some extent with Principal Coordinate Analysis (PCA) of two and three-dimensional plots. The variability revealed by morphological and molecular profile were found to be non-comparable. This study indicated the presence of high genetic diversity among collected yellow sarson germplasm, which could be used for developing for breeding and germplasm management purposes.

One of the most crucial aspects of biological diversity for conservation strategies is genetic diversity, particularly in rare and narrow endemic species. Our study is the first attempt to utilize SCoT markers to check the genetic diversity in Iran. We used 115 plant samples. Our objectives were 1) to check genetic diversity among Geranium species 2) Genetic structure of the Geranium 3) Do the Geranium species exchange genes? 4) To detect isolation by distance among the Geranium species. We used traditional morphological and molecular methods to assess genetic diversity and genetic structure in the Geranium species. A total of 129 amplified polymorphic bands were generated across 13 Geranium species. The size of the amplified fragments ranged from 150 to 3000 bp. G. stepporum showed the highest values for the effective number of alleles (Ne = 1.30) and Shannon information index (I =0.35). Significant ANOVA results (P <0.01) showed differences in quantitative morphological characters in plant species. G. sylvaticum showed high genetic diversity. Mantel test showed a significant correlation (r = 0.17, p=0.0002) between genetic distance and geographical distance, so isolation by distance (IBD) occurred among the Geranium species. According to the SCoT markers analysis, G. kotschyi and G. dissectum had the lowest similarity, and the species of G. sylvaticum and G. pratense had the highest similarity. The present study revealed that a combination of morphological and SCoT methods could distinguish the species of Geranium.

ABSTRACT Hymenaea courbaril is a rare species in the riparian areas of the state of Sergipe, Brazil. This species is known as Brazilian cherry or Brazilian copal and it occurs in fragments of the Rainy Forest and in the transition zones between the Rainy Forest and the Caatinga Biomes. This work was carried out, in order to quantify the genetic diversity of the remaining population of Brazilian cherry, by RAPD markers. In a studied area of 100 ha in the low course of the São Francisco River, only 15 individuals were observed. The analyzed parameters were as follows: Jaccard’s genetic similarity, the number of observed alleles, the number of effective alleles, the genetic diversities of Nei, the percentages of the polymorphic loci, the genetic diversities when using the Shannon index and the coancestry coefficient. There was no correlation between the genetic distances and the geographical distances. Despite the low number of individuals, high genetic diversity was observed, a fact that contributes to the development of strategies for the conservation of the species.

The Mean

The goal of this study was to assess the genetic diversity of Nicaraguan populations of Cedrela odorata using Random Amplified Polymorphic DNA (RAPD) markers. Thus, genomic DNA was isolated from leaf samples collected from ninety-two trees belonging to five Nicaraguan natural populations of C. odorata. The mean number of alleles per locus, effective number of alleles per locus, percentage of polymorphic loci, genetic diversity (He ) of Nei and diversity index (Ho ) of Shannon were estimated for each population assuming that the populations were in HardyWeinberg equilibrium. Total genetic diversity was partitioned in intrapopulational and interpopulational diversity using Nei’s genetic differentiation (GST) and through an Analysis of Molecular Variance (AMOVA). The ΦST matrix was used to construct a dendrogram by the neighbor-joining method. According to values of both He and Ho , Esquipulas (Deparment of Matagalpa) presented the lowest diversity level; while La Trinidad (Department of Estelí) showed the highest diversity level. Genetic differentiation was calculated obtaining a GST value of 13.36%. AMOVA also showed a similar differentiation value ΦST =13.81%). Neighbour-joining dendrogram clustered the five populations in two groups, where the group formed by La Trinidad and El Refugio (Department of Granada) presented the biggest differentiation. Correlation between genetic and geographical distances was not found.
