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.

AbstractGenetic diversity and phylogenetic analyses of 24 species, representing nine sections of the genus Galium (Rubiaceae), have been made using the Inter Simple Sequence Repeats (ISSR), Randomly Amplified Polymorphic DNA (RAPD), and combined ISSR and RAPD markers. Four ISSR primers and three RAPD primers generated 250 polymorphic amplified fragments. The results of this study showed that the level of genetic variation in Galium is relatively high. RAPD markers revealed a higher level of polymorphism (158 bands) than ISSR (92 bands). Clustering of genotypes within groups was not similar when RAPD and ISSR derived dendrograms were compared. Six clades can be recognized within Galium, which mostly corroborate, but also partly contradict, traditional groupings. UPGMA-based dendrogram showed a close relationship between members of section Leiogalium with G. verum and G. humifusum (sect. Galium), and G. angustifolium (sect. Lophogalium). Principal coordinated analysis, however, showed some minor differences with UPGMA-based dendrograms. The more apomorphic groups of Galium form the section Leiogalium clade including the perennial sections Galium, Lophogalium, Jubogalium, Hylaea and Leptogalium as well as the annual section Kolgyda. The remaining taxa of Galium are monophyletic.

Genetic diversity estimation among different species is an important tool for genetic improvement to maximize the yield, desirable quality, wider adaptation, pest and insect resistance that ultimately boosting traditional plant breeding methods. The most efficient way of diversity estimation is application of molecular markers. In this study, twenty random amplified polymorphic DNA (RAPD) primers were utilized to estimate the genetic diversity between ten sunflower genotypes. Overall 227 bands were amplified by 20 primers with an average of 11.35 bands per primer. RAPD data showed 86.34% polymorophic bands and 13.65% of monomorophic bands. Genetic similarity was ranged from 50.22% to 87.22%. The lowest similarity (50.22%) was observed between FH-352 and FH-359 and the maximum similarity 87.22% was observed between A-23 and G-46. Polymorphic information content (PIC) values were varying from 0.05 to 0.12 with a mean of 0.09. Cluster analysis based on RAPD results displayed two major distinct groups 1 and 2. Group-2 contains FH-352 which was the most diverse genotype, while group-1 consists of few sub groups with all other genotypes. Ample diversity was found in all the genotypes. Present study reveals novel information about sunflower genome which can be used in future studies for sunflower improvement.

The genetic variability of 40 accessions of_C. arabica was evaluated using a combination of the random amplified polymorphic DNA (RAPD) technique and restriction digestion of genomic DNA. The genetic variability and the relatedness among all accessions were initially evaluated using 195 RAPD primers which revealed a very low level of genetic variation. To improve the efficiency in the detection of polymorphism, the genomic DNA of all accessions were submitted to digestion with restriction endonucleases prior to PCR amplification. A total of 24 primers combined with restriction digestion of DNA rendered 318 bands, of which 266 (83.65%) were polymorphic. The associations among genotypes were estimated using UPGMA-clustering analysis. The accessions were properly clustered according to pedigree and agronomic features. The ability to distinguish among coffee accessions was greater for RAPD plus restriction digestion than for RAPD alone, providing evidences that the combination of the techniques was very efficient for the estimation of genetic relationship among_C. arabica genotypes.

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.

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.

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.

In this study research was conducted to evaluate the feasibility of characterizing genetic variation within camellia species using random amplified polymorphic DNAs (RAPD) markers. Eight varieties of species Camellia japonica and four varieties of species Camellia reticulata, provided by the America Camellia Society, Fort Valley, Ga., were investigated. RAPD profiles generated by five selected 10-based random primers (out of 20 primers) exhibited distinct patterns of amplified bands for all 12 tested varieties. A total of 344 bands were produced among the eight varieties of species C. japonica, with an average of 8.6 bands, ranging from 220 to 2072 bp in size, scored per primer. Among the 344 amplified bands, 74.4% of the bands presented polymorphic. The four varieties of species C. reticulata produced a total of 180 markers, with an average percentage of 57.8% polymorphisms. The amplified bands were in the range of 236–1760 bp. An average of nine amplified bands was generated per primer. The large percentages of polymorphisms displayed among 12 varieties within the two different species indicate that the expected genetic diversity among varieties within camellia species existed. It was concluded that the RAPD molecular markers are capable of revealing appreciable levels of genetic variation within camellia species.

Low Levels

Random amplified polymorphic DNA (RAPD) markers were used to characterize genetic variation in disjunct Newfoundland populations of red pine (Pinusresinosa Ait.) for comparison with individuals from throughout the mainland range of red pine. Red pine demonstrated a largely monomorphic profile for 69 arbitrary oligonucleotide primers. DNA samples from white spruce (Piceaglauca (Moench) Voss) and black spruce (Piceamariana (Mill.) B.S.P.) that were screened together with red pine for 11 oligonucleotide primers showed abundant polymorphisms, confirming the genetic heterogeneity that characterizes these Boreal Zone spruces. Results with RAPD markers correspond with genetic diversity estimates using isozyme gene markers for both spruce species and red pine. RAPD markers provided further confirmation of low levels of genetic variation for a random sample of the red pine genome. A period of between 8000 and 10 000 years of isolation on the island of Newfoundland has resulted in very little detectable genetic differentiation of island populations from mainland populations, and the mainland populations have not recovered from losses of genetic diversity following a hypothesized genetic bottleneck that may have been experienced during glacial episodes of the Holocene. The low levels of genetic variation observed in red pine demonstrate the long time periods required for recovery following a loss of genetic diversity in long-lived, long-generation organisms like trees.

Random amplified polymorphic DNA (RAPD) markers are widely used for evaluating the genetic relationship of crop germplasm. Five different landraces of yacon (Smallantus sonchifolius (Poepp. and Hendl.) H. Robinson; Asteraceae) collected in various countries and showing different morphological traits were investigated using a total of 61 decamer primers. A total of 282 RAPD markers were scored and 28.7% of them were polymorphic at least within landraces. RAPD markers generated by one primer (OBP14) discriminated between all landraces. Markers were used to calculate genetic similarity coefficient and to build a dendrogram representing the genetic relationship between analysed landraces. The results suggest that RAPD markers could be used as a reliable tool to perform fingerprinting studies in Smallantus sonchifolius genome. This is the first report on the use of RAPDs to evaluate genetic distance and to distinguish between different landraces in yacon. &nbsp;
