Ipomoea Species

To understand the prospects of applying the RAPD technique to assay genetic diversity in Ipomoea, four species (I. batatas, I. trifida, I. triloba, and I. ×leucantha) were analyzed for RAPD molecular markers. Six accessions of each species were used. Significant RAPD polymorphisms were detected within each species. Of 20 primers used, nine produced clear scorable polymorphic bands. The number of polymorphic bands produced per primer ranged from two to nine. Pair-wide genetic distance was calculated based on “band sharing”. The SAS-CLUSTER procedure was used to build a hierarchical species dendrogram. The four species were clearly separated by the clustering, which agrees with their existing taxonomic relationship. This study shows that RAPD analysis can be a powerful tool for identifying duplicates of germplasm acessions and for assessing genetic diversity. The procedures are relatively inexpensive and easy to perform and could be valuable in preliminary assessment of field genebank collections to separate species and indicate duplications in collected material.

Ten morpho-agronomic traits and 80 random amplified polymorphic DNA (RAPD) molecular markers were used to survey genetic diversity in 25 chickpea genotypes. Analysis of variance revealed significant variability among different genotypes for morpho-metric traits. The cluster analysis done using morpho-metric traits grouped 25 genotypes into seven and six clusters in Environment I (Env. I) and Environment II (Env. II), respectively. Three genotypes viz., ICCV-96904, HPG-17, ICCV-95503 and L-HR-1 belonging to diverse clusters were identified divergent and may use in heterosis breeding programme. Of 80 random RAPD markers, 25 were found polymorphic. Three major clusters were identified using 25 polymorphic RAPD markers. The genetic similarity coefficient among genotypes ranged from 0.57 to 0.91. The average polymorphic information content (PIC) for 25 RAPD markers ranges from 0.12 to 0.40. D2-statistic, RAPD analysis and study of genotypes performance revealed sufficient genetic diversity among chickpea genotypes which would be useful in future breeding programme.

AbstractPopulation genetic diversity contributes to the protection and utilization of germplasm resources, especially via genetic breeding. In the present study, start codon targeted polymorphism (SCoT) molecular markers were used to study the genetic diversity of 278 individuals from 10 Prunus sibirica L. populations in Inner Mongolia. A total of 289 polymorphic bands were amplified with 23 SCoT primers, showing a polymorphism percentage of 98.87% and an average of 12.6 polymorphic bands per primer. The SCoT21, SCoT32, and SCoT53 primers amplified up to 17 bands, and the polymorphism percentage was 100%. The minimum number of bands amplified by SCoT25 was 9, and the polymorphism percentage was 90%. Therefore, SCoT molecular markers were shown to be highly polymorphic and suitable for genetic diversity studies of P. sibirica in Inner Mongolia. The analysis of molecular variance showed that 39% of the observed genetic differentiation occurred among populations and 61% occurred within populations, indicating that the genetic differentiation within populations was greater than that among populations. The results of the unweighted pair-group method with an arithmetic cluster analysis, principal coordinate analysis and STRUCTURE analysis were basically the same and divided the 278 individuals from the 10 populations into 2 groups. The results indicated that the efficient SCoT molecular marker-based genetic diversity analysis of P. sibirica in Inner Mongolia can provide a reference for P. sibirica variety breeding and resource development.

Knowledge of genetic diversity and relationships among maize inbred lines is indispensable to a breeding program. Our objective was to investigate the level of genetic diversity among maize inbred lines. Eighty-three maize inbred lines obtained from SCDA Turda were genotyped using 20 decamer primers. These primers generated, among the studied genotypes, a number of polymorphic bands comprised between 17 bands (OPA 03) and 7 bands (OPAB 11). The highest numbers of polymorphic bands were obtained with primer OPA 03, respectively 17 bands, followed by OPA 01, OPB 08 (16 polymorphic bands) and OPX 03 and OPAL 20 (13 polymorphic bands). Genetic distances were established using Nei Li/Dice coefficent and an UPGMA dendrogram was constructed with FreeTree software. The built dendrogram shows phylogenetic relationships between the analysed biological material.

Lelana Ne, Wiyono S, Giyanto, Siregar IZ. 2018. Genetic diversity of Falcataria moluccana and its relationship to the resistance of gall rust disease. Biodiversitas 19: 12-17. The use of cultivars that are resistant to a particular disease is one strategy that could mitigate the incidence of gall rust disease on Falcataria moluccana. Previous studies on the genetic diversity of F. moluccana did not attempt to link that genetic diversity to gall rust disease resistance. This research was carried out using RAPD analysis to determine the preliminary information on the association between different markers and the resistance to gall rust disease. The analysis evaluated a total of 20 pairs of healthy and infected F. moluccana trees that were classified based on their disease severity level. The RAPD primers used in this study were as follows: OPA-05, OPA-08, OPA-10, OPA-13, OPA-18, OPB-07, OPD-13, OPF-02, and OPG-05. The results showed that each RAPD primer produced a varying number of polymorphic bands, ranging from 3 to 12 bands, with a total of 80 polymorphic bands. Despite the number of loci analyzed, however, no specific polymorphic bands were found that could distinguish between healthy and diseased trees. This was supported by principal component analysis, which showed that healthy and diseased populations were not distributed separately. The structure analysis also showed that the healthy and diseased populations were not different.

Croton (Puring) is a native  plant of Indonesia which has varied leaf shapes and colors. The diversity of croton increase through hybridization. The information on genetic diversity and relationship between parent and its offspring of crotons is very limited. This study aims to analyze the genetic diversity of cultivar Mawar (MW) and Walet (W) as parent compare to their offspring i.e, Black Marlet (BM), Kingkit 1 (KA), Kingkit 2 (KB), and Kamaratih (KM) using RAPD markers. This study used DNA extraction from the fresh leaf of six cultivars. The next steps were DNA quantification, primary optimization, DNA amplification with PCR, and electrophoresis. Statistical analysis was carried out using Genalex software. A total of 40 primers were screened, out of which 10 were selected for the analysis of genetic diversity. A total of 106 polymorphic bands were generated, ranging from 130 to 1850 bp. The results of RAPD analysis showed that Mawar as female parent had the highest polymorphic bands percentage of 69.01%, while Walet as male parent and its offspring ranged from 31.15 % to 43.94%. The genetic distance of the offspring with Walet ranged from 0.176 to 0.234 and genetic distance of the offspring with Mawar ranged from 0.314 to 0.372. It was indicated that all of offspring were closer to the male parent.

Molecular markers were used to assess genetic diversity in basil (Ocimum L. spp., Lamiaceae). Using randomly amplified polymorphic DNA (RAPD) analysis, 11 primers generated 98 polymorphic bands, ranging from 300 to 2,000 base pairs, that discriminated among 37 accessions across nine Ocimum spp. Means of genetic similarities within Ocimum spp. showed that the domesticated species, O. minimum L. (0.887), O. basilicum L. (0.769), and O. ×citriodorum Vis. (0.711) had highest similarity indices within species, while the nondomesticated, O. americanum L. (0.580), O. gratissimum L. (0.408), and O. kilimandscharicum Guerke (0.559) showed the lowest similarity. RAPD results indicated that O. minimum should not be considered a distinct species but rather a variety of O. basilicum. Consistent clusters among all but one of the O. ×citriodorum spp., all containing citral as the major constituent, were identified using bootstrap analysis. RAPD analysis was useful in discriminating among Ocimum spp., although within species resolution will require a higher number of polymorphic bands.

Genetic variability among accessions of Russian thistle (Salsola tragus L.) from California was investigated using allozymes and DNA-based molecular markers. Aspartate aminotransferase and 6-phosphogluconate dehydrogenase displayed two multienzyme phenotypes that were widespread in plants throughout the state. Random amplified polymorphic DNA analysis was conducted on samples of the two isoenzymic phenotypes collected throughout California, as well as additional accessions from France and Turkey and Salsola paulsenii Litv. Six primers produced 23 polymorphic bands. Analysis of the patterns of bands by calculation of simple matching coefficients and cluster analysis confirmed the genetic distinctness of the two isoenzymic phenotypes of S. tragus; S. paulsenii was markedly different from both types. Mean fruit weights from plants grown under similar conditions were different between the two types as well. These results and preliminary cytological analysis together suggest that the two types are actually two different species of Salsola, only one of which has been previously recognized. Analysis of the DNA-based markers suggests that one of the genetic entities may be closely related to Salsola found in Europe, while the area of origin of the second entity is currently obscure.Key words: allozyme, genetic diversity, RAPD assay, Salsola tragus, Salsola paulsenii.
