Ho VT, Ngo QNg. 2017. Short Communication: Using RAPD technique to evaluate genetic diversity of longan (Dimocarpus longan) population in Vietnam. Biodiversitas 18: xxxx. Longan (Dimocarpus longan L.) is an important fruit plant in Vietnam where several cultivars and landraces are being cultivated. Presently, the identification of longan cultivars and landraces is mainly based on personal experience relying on morphological traits leading the difficulty of genetic conservation and longan breeding. In this study, genetic richness and relativeness of 36 longan accessions collected from different provinces in Vietnam were evaluated by using 30 Random Amplified Polymorphic DNA (RAPD) primers. Our results reveal that there is the large variation of genetic background of studied longan accessions with separate groups in the obtained dendrogram. We also identified the combination of different RAPD markers could help to identify 15 longan genotypes. The results from this project could provide valuable information which is necessary for classifying, identifying plant origins, breeding and conserving programs of longan in Vietnam.

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.

Random amplified polymorphic DNA (RAPD) markers were used to assess genetic diversity in Bambara groundnut (Vigna subterranea L.) germplasm using 25 African accessions from the collection in the International Institute for Tropical Agriculture, Ibadan, Nigeria. Fifty random decamer primers were screened to assess their ability to detect polymorphism in bambara; 17 of them were selected for this study. Considerable genetic diversity was found among the V. subterranea accessions studied. The relationships among the 25 accessions were studied by cluster analysis. The dendrograms showed two main groups of accessions mainly along the lines of their geographic origin. It is concluded that RAPD can be used for germplasm classification in bambara groundnut and hence for improving this crop.Key words: germplasm, PCR, RAPD, Vigna subterranea.

Camellia sinensis is a beverage tree crop native to Southeast Asia and introductions have been made into several nonindigenous countries. No systematic assessment of genetic variability in tea has been done anywhere. In this study, random amplified polymorphic DNA (RAPD) analysis was used to estimate genetic diversity and taxonomic relationships in 38 clones belonging to the three tea varieties, assamica, sinensis, and assamica ssp. lasiocalyx. Extensive genetic variability was detected between species, which was partitioned into between and within population components. Seventy percent of the variation was detected within populations. Analyses based on band sharing separated the three populations in a manner consistent with both the present taxonomy of tea and with the known pedigrees of some clones. RAPD analysis also discriminated all of the 38 commercial clones, even those which cannot be distinguished on the basis of morphological and phenotypic traits.Key words: genetic diversity, RAPDs, Camellia sinensis.

Random amplified polymorphic DNA (RAPD) markers were used to study genetic diversity in dog samples belonging to populations of German Shepherd and Japanese Spitz. A total of twelve samples were typed using eight RAPD primers. Out of eight primers, three primers gave result in six individuals of dogs. The phylogenetic tree constructed by the neighbor joining method based on Nei. Original measures revealed highest genetic identity found in German Shepherd as 0.9444 and highest genetic distance as 1.2809. The analysis predicts the number of polymorphic loci as 15 and the percentage of polymorphic loci as 83.3.

Surian Toona sinensis Roem is one of the most widely planted species in Indonesia. This study aimed to estimate the genetic diversity between a number of surian populations in a progeny test using RAPD markers, with the goal of proposing management strategies for a surian breeding program. Ninety-six individual trees from 8 populations of surian were chosen as samples for analysis. Eleven polymorphic primers (OP-B3, OP-B4, OP-B10, OP-H3, OP-Y6, OP-Y7, OP-Y8, OP-Y10, OP-Y11, OP-Y14, and OP-06) producing reproducible bands were analyzed for the 96 trees, with six trees per family sampled. Data were analyzed using GenAlEx 6.3, NTSYS 2.02. The observed percentage of polymorphic loci ranged from 18.2% to 50%. The mean level of genetic diversity among the surian populations was considered to be moderate (He 0.304). Cluster analysis grouped the genotypes into two main clusters, at similarity levels of 0.68 and 0.46. The first two axes of the PCoA explained 46.16% and 25.54% of the total variation, respectively. The grouping of samples into clusters and subclusters did not correspond with family and their distances, but the grouping was in line with the genetic distances of the samples.

SUMMARYRandom amplified polymorphic DNA markers (RAPD) were used to visualize the genetic diversity within and between infrapopulations of Schistosoma mansoni recovered from the natural vertebrate host, Rattus rattus, trapped at an insular Guadeloupean focus. Phenotypes were characterized by the sex of the parasites and by 8 polymorphic markers generated by 3 primers. Among the 212 parasite individuals recovered from 10 infected rats, 78 genotypes were characterized. All the hosts naturally infected harboured multiple parasite genotypes with a maximum diversity of 28 genotypes/host. Phenotypic and genotypic diversity calculated by Shannon-Wiener's indices and Lynch and Milligan's estimators respectively is, on average, greater within than between hosts. Considering the very low snail infection rates observed in this focus and the rapid turnover of the vertebrate hosts, our results suggest that the high mobility of the vertebrate host and/or plurimiracidial snail infections could be factors responsible for parasite genetic diversity within hosts.

Abstract. Soybeans tempeh (tempeh) is processed by fermentation using Rhizopus spp. Tempeh is an important source of protein in Indonesia. The traditional inoculum in fermentation locally is known as Usar which is made from the leaves of Hibiscus tiliaceus. However, Rhizopus information from Usar is still limited. Therefore, this study aims to identify and investigate the genetic diversity of Rhizopus species from Usar and tempeh based on the Internal Transcribed Spacer (ITS) sequence and the Random Amplified Polymorphic DNA (RAPD) markers. Twenty-three Rhizopus strains were isolated from Usar and ten Rhizopus strains were isolated from tempeh. Based on ITS sequences, the isolates were similar to R Rhizopus microsporus (30 isolates) and Rhizopus delemar (3 isolates) with 98-99% similarity. The genetics of R. microsporus and R. delemar are varied and different from the genetics of R. microsporus from tempeh. The growth temperature of R. microsporus varies from 33 to 48°C and R. delemar can grow to a maximum at 33°C. The role of R. microsporus and R. delemar from Usar in determining the quality of tempeh is still limited. Therefore, it needs to be investigated further.
