Ficus carica L. is one of the most ancient fruit trees cultivated in Persia (Iran). The conservation and characterization of fig genetic resources is essential for sustainable fig production and food security. Given these considerations, this study characterizes the genetic variability of 21 edible F. carica cultivars in the Fars Province using random amplified polymorphic DNA (RAPD) markers. The collected cultivars were also characterized for their morphological features. A total of 16 RAPD primers produced 229 reproducible bands, of which, 170 loci (74.43%) were polymorphic with an average polymorphic information content (PIC) value of 0.899. Genetic analysis using an unweighted pair-group method with arithmetic averaging (UPGMA) revealed genetic structure and relationships among the local germplasms. The dendrogram resulting from UPGMA hierarchical cluster analysis separated the fig cultivars into five groups. These results demonstrate that analysis of molecular variance allows for the partitioning of genetic variation between fig groups and illustrates greater variation within fig groups and subgroups. RAPD-based classification often corresponded with the morphological similarities and differences of the collected fig cultivars. This study suggests that RAPD markers are suitable for analysis of diversity and cultivars’ fingerprinting. Accordingly, understanding of the genetic diversity and population structure of F. carica in Iran may provide insight into the conservation and management of this species.

ABSTRACT Brave bean (Capparis flexuosa L.) is a Caatinga species that is used as forage, mainly during the dry season when some plant species lose their leaves. The aim of this study was to assess genetic diversity within and among brave bean populations using Random Amplified Polymorphic DNA (RAPD) markers. Brave bean leaves were collected from 30 accessions in the following municipalities of Paraíba state, Brazil: Barra de Santa Rosa (BSR), Cuité (C), São João do Cariri (SJC), Damião (D), Baraúna (B), and Picuí (P). DNA extraction followed the standard methodology of CTAB with modifications. RAPD analyses were carried out using 18 primers, and polymorphism of the amplified DNA fragments was visualized using agarose gel electrophoresis. Data were used to calculate Jaccard Similarity Coefficient values, which were then used to group samples with the Unweighted Pair Group Method with Arithmetic Mean. Cophenetic Correlation Coefficient, Stress, and Distortion Coefficient values were also calculated from these analyses. Band polymorphism was generated with 14 primers, but the sampled populations showed low numbers of polymorphic loci (27 in BSR, 18 in C, 7 in SJC, 9 in D, and 0 in B and P). The highest polymorphic information content was found in samples from the BSR (9 groups), C (22 groups), SJC (7 groups), and D (6 groups) municipalities. In the interpopulation analysis, 34 groups were formed, the matrices of which showed high cophenetic correlations (0.95 to 0.98), but low stress (12.9 to 17.45%) and distortion (3.05%). Therefore, results showed that there was genetic variability both among and within brave bean populations.

Molecular Genetic Diversity

Random Amplified Polymorphic DNA (RAPD) markers were used to study the molecular genetic diversity analysis among six BARI released lentil varieties viz. BARI masur-1, BARI masur-2, BARI masur-3, BARI masur-4, BARI masur-5 and BARI masur-6. PCR amplified products were visualized on 1.0% agarose gel and the band for each primer were scored. Ten RAPD markers were used in this study. Out of them 7 primers showed amplification of 53 DNA fragments with 60.37% of them being polymorphic. The highest number of polymorphic loci was noticed in the variety BARI masur-3. The same variety also showed maximum Nei’s gene diversity value (0.0552). The highest Nei’s genetic distance (0.5002) was observed in BARI masur-1 vs. BARI masur-5 whereas, the lowest genetic distance (0.0692) was found in BARI masur-1 vs. BARI masur-2. The unweighted pair group method of arithmetic mean (UPGMA) dendrogram based on Nei’s genetic distance grouped the six cultivars into two main clusters. BARI masur-1, BARI masur-2 and BARI masur-3 were in cluster I and BARI masur-4, BARI masur-5 and BARI masur-6 were in cluster II. The cultivar BARI masur-4 was closest to the cultivar BARI masur-6 with the lowest genetic distance (0.0972) and the highest genetic distance (0.5002) was found between BARI masur-1 and BARI masur-5. The RAPD markers were found to be useful in molecular characterization of lentil varieties which could be utilized by the breeders for the improvement of lentil cultivars.

Sugarcane somaclones and their sources varieties were analyzed by RAPD molecular markers to check the variation at molecular level based on 1.4% agarose gel electrophoresis (AGE). Six RAPD primers generated 237 bands with average 39.5 varied from 15 to 63 with size ranging 145 - 1000 bp among the four sugarcane varieties and their 12 somaclones. Genetic diversity or polymorphism information content (PIC) value ranged from 0.39 to 0.50 for all loci across the 4 varieties and their 12 somaclones based on RAPD markers. Dendrogram based on linkage distance using unweighted pair group method of arithmetic means (UPGMA) based on 6 RAPD primers indicated segregation of the 4 sugarcane varieties and their somaclones into two main clusters at linkage distance 36. Variety Isd 39 was observed in main cluster C1 while its (Isd 39) somaclones and other varieties (Isd 37, Isd 38 and Isd 40) and also their somaclones were found in main cluster C2 having different sub-clusters. Theirfore, it may be concluded that RAPD markers can be used for identification of somaclonal variation and the relationship between sources varieties and their somaclones.Plant Tissue Cult. & Biotech. 25(2): 223-229, 2015 (December)

A polymerase chain reaction (PCR) based approach, namely random amplified polymorphic DNA (RAPD) analysis was applied to l0 varieties of onion (Allium cepa) in order to assess the degree of polymorphism within the genes and to investigate if this approach was suitable for genetic studies of onion. For this study, ten cultivars of onion were evaluated for variability using a set of 15 random l0-mer primers. The polymorphisms in PCR amplification products were subjected to the unweighed pair group method for arithmetic averages (UPGMA) and plotted in a phenogram. The dendogram constructed from the similarity data showed that all the cultivars analyzed were related. Among them, 12 of the primers revealed scorable (168 bands) polymorphisms between cultivars of A. cepa and the rest did not show polymorphism in their genetic level. In this study, it was found that Bermis and India-2 were more dissimilar and on the other hand, Faridpuri and Bhati were the most similar in their genetic level.

In this work, the part of the squash core collection, maintained in the Greek Gene Bank, was assessed using the morphological and molecular data. Sixteen incompletely classified accessions of the squash were characterized along with an evaluation of their resistance against two isolates of Fusarium oxysporum. A molecular analysis using Random Amplified Polymorphic DNA (RAPD) markers was also performed, revealing high level of polymorphism. To study the genetic diversity among the squash accessions, a clustering procedure using Unweighed Pair Group Method and Arithmetic Average (UPGMA) algorithm was also adopted. Two independent dendrograms, one for the morphophysiological and one for molecular data were obtained, classifying the accessions into two and three main clusters, respectively. Despite the different number of the clusters there were many similarities between these two dendrograms, and a third dendrogram resulting from their combination was also produced, based on Gower's distance and UPGMA clustering algorithm. In order to determine the optimal number of clusters, the upper tail approach was applied. The more reliable clustering of the accessions was accomplished using RAPD markers as well as the combination of the two different data sets, classifying the accessions into three significantly different groups. These groups corresponded to the three different cultivated species of C. maxima Duch., C. moschata Duch., and C. pepo L. The same results were also obtained using Principal Component Analysis.

Tolerant Line

Twenty six rice lines of PBRC (salt tolerant line-20) × BRRI dhan-29 were used to evaluate salinity tolerance at the seedling stage and tested for salt tolerance using RAPD markers. Salinity screening was done using hydrophonic system at the greenhouse following IRRI standard protocol. Among the studied line, ten were moderately salinity tolerant, nine susceptible and rest of the lines highly susceptible. For assessing genetic diversity and relationship of F3 rice lines including two parents were tested against PCR-based Random Amplified Polymorphic DNA (RAPD) technique using three arbitrary decamer primers; OPA02, OPC01, and OPC12. Selected three primers generated a total of 14 bands. Out of 14 bands, 12 bands (86.67%) were polymorphic and 2 bands (13.33%) were monomorphic. The Unweighted Pair Group Method of Arithmetic Means (UPGMA) dendrogram constructed from Nei’s (1972) genetic distance produced 2 main clusters of the 28 rice genotypes. Most of the moderately tolerant lines and PBRC (STL-20) (tolerant variety) were grouped in same cluster due to lower genetic distance, while maximum susceptible along with BRRI dhan29 (susceptible variety) showed higher genetic distance with PBRC (STL-20) and moderately tolerant lines. This result indicates that the lines which formed grouped together, they are less diversed. On the other hand the lines remain in different clusters or different groups, are much diversed. Thus RAPD perform a potentially simple, rapid and reliable method to evaluate genetic diversity and molecular characterization as well. Res. Agric., Livest. Fish.6(2): 215-225, August 2019

Electrophoretic Patterns

Random amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and to discriminate among 33 Greek olive (Olea europaea L.) cultivars. Three feral forms from Crete and five foreign cultivars recently introduced into Greece were also included. Nineteen primers were selected which produced 64 reproducible polymorphic bands in the 41 olive genotypes studied, with an average of 3.4 informative markers per primer. The RAPD markers resulted in 135 distinct electrophoretic patterns, with an average of 7.1 patterns per primer. Based on either unique or combined patterns, all genotypes could be identified. Genetic similarities between genotypes were estimated using the Dice similarity index and these indicated that a high degree of diversity exists within the Greek olive germplasm. Using the unweighted pair-group method (UPGMA) most cultivars were clustered into two main groups according to their fruit size or commercial use (table or olive oil). However, poor correlation was detected between clustering of cultivars and their principal area of cultivation. RAPD marker data were subjected to nonmetric multidimentional scaling (NMDS) which produced results similar to those of the UPGMA analysis. The results presented here contribute to a comprehensive understanding of cultivated Greek olive germplasm and provide information that could be important for cultural purposes and breeding programs.

Application of Inter Simple Sequence Repeats and Random Amplified Polymorphic DNA markers in Curcuma aromatica collected from 4 different populations of Odisha. A dendrogram was constructed through sequential agglomerative hierarchial and nested (SAHN) clustering and unweighted pair group method with arithmetic mean (UPGMA) analysis using Jaccard’s similarity coefficient of combined markers using this particular species. Two major clusters were found i.e., cluster-I (Koraput-1, Koraput-2, Koraput-3, G.Udaigiri-1, G.Udaigiri-2, G.Udaigiri-3 and Phulabani-1, Phulabani-2, Phulabani-3) and cluster-II (Raikia-1, Raikia-2 and Raikia-3). The clustering pattern also revealed moreover the extent of genetic similarity between germplasms collected from those populations. This technique would be further utilized for identification and tagging of important novel gene present in different taxa or improvement work in family Zingiberaceae. This study would be of immense significance for conservation and characterization of important medicinal plant species.

Tomato Genotypes

The present investigation was carried out for assessment of genetic diversity among the 28 tomato genotypes though three random amplified polymorphic DNA (RAPD) markers. A total of 15 distinct DNA fragments ranging form 100-1000 bp were amplified by using three selected primers of which 5.00 polymorphic bands per primer and over all polymorphic loci was 100 percent. The extent of genetic diversity among these genotypes was computed through parameters of genetic diversity and Shanon’s information indices. The highest genetic distance was observed among the accession Cl-3d-0-99 (V93)  vs. F1 (G X V12), F1 (G X V17), F1 (G X V29) and  Durch fuegel  (G) vs. F1 (G X V17) and F1 (G X V93) vs. F1 (G X V12), F1 (G X V17), while the lowest genetic distance was observed among the accessions Fut. Wed Abrid (V94) vs. Sunlight pole (V67) and F1 (V67 X VG) vs. F1 (V17 X VG), F1 (V93 X VG) and F1 (V93 X V17) vs. F1 (V17 X VG), F1 (V67 X VG), F1 (V93 X VG). The Unweighted Pair Group Method of Arithmetic Mean (UPGMA) dendrogram based on Nei’s genetic distance divided the genotypes into two main clusters: A & B. Cluster ‘A’ consists of 19 accessions and cluster ‘B’ consists of 9 accessions. The information generated from this study could be useful in gene mapping and marker assisted breeding for future tomato breeding programs. Progressive Agriculture 29 (4): 276-283, 2018
