Abstract Conservation of bamboos for future exploitation as fuel, fibre and as an ingredient for cosmetics depends on knowledge of its natural genetic variation. The study of molecular genetic diversity in bamboos will provide important information for its conservation. This article reports on the genetic diversity in 25 species representing five genera of bamboos found in Indonesia using Random Amplified Polymorphic DNA (RAPD) molecular markers. Out of 40 primers, 24 primers produced 1107 total bands and 86.21% of polymorphic bands across the 25 species. Sixteen bands were uniquely found in one species only and their presence or absence helped to define nine bamboo species. RAPD band sizes ranged from 162 to 2247 base pairs. A dendrogram based on the similarity coefficient of Dice divided the bamboo species into three big clusters. In conclusion, RAPD can capture the diversity among five different bamboo genera and has a great potential to be used in the study of genetic diversity in Indonesian bamboos.

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.

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.

Of the 30 species (including five varieties) of the genus Swertia in Nepal, nine have been reported to possess medicinal properties. Among these, S. chirayita is the most valuable species, with high demand in domestic and international markets. Nepal’s S. chirayita and related species are being recklessly exploited for commercial purposes. Two problems that have emerged with this lucrative market are (a) adulteration and fraudulent labeling of S. chirayita, and (b) depletion of S. chirayita and allied species from their natural habitats. To address the problem of adulteration and conservation, we studied molecular genetic diversity in S. chirayita populations and developed a molecular diagnostic tool for the purposes of authentication. We studied intra-specific genetic diversity in S. chirayita using Polymerase Chain Reaction (PCR)-based Random Amplified Polymorphic DNA (RAPD) technique. As a preliminary step, we identified optimal RAPD-PCR reaction and cycling conditions by varying PCR reaction parameters such as concentration of template DNA, MgCl2, dNTPs, primer, Taq DNA polymerase and RAPD-PCR programs. The optimized PCR reaction and cycling conditions were then used in subsequent RAPD profiling experiments for the study of genetic diversity within S. chirayita populations from various geographical locations. Genetic diversity characterization of S. chirayita populations at the molecular level would furnish information with significant applications in the conservation and sustainable utilization of S. chirayita and its allied species in Nepal.

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.

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.

Castor (Ricinus communis L.), known as castor oil plant or castor bean, is a non-edible oilseed crop. In the present study, the genetic diversity among 54 samples (3 wild and 51 cultivated) collected worldwide was evaluated using inter-simple sequence repeats (ISSRs) and random amplified polymorphic DNA (RAPD) markers. A total of 9 ISSR primers produced 83 high-resolution bands with 61 (74.53%) as polymorphic. The percentage of polymorphic bands per primer and the genetic similarity coefficient ranged from 54.55% (UBC-836) to 100% (UBC-808) and from 0.74 to 0.96, respectively. A total of 11 out of 20 RAPD primers amplified unique polymorphic products with an average percentage of polymorphic bands of 60.98% (56 polymorphic bands out of a total of 90 bands obtained). The percentage of polymorphic bands per primer ranged from 25% (OPA-02 and B7) to 90.91% (B21) with the genetic similarity coefficient ranging from 0.73 to 0.98. The unweighted pair group method with arithmetic averages (UPGMA) dendrogram using two molecular markers divided 54 castor genotypes into three groups. Furthermore, based on morphological data, all 54 castor varieties were grouped into three main clusters. The genetic diversity analysis based on two molecular makers showed that most varieties from China were closely related to each other with three varieties (GUANGDONGwild, ZHEJIANGWild, and HANNANWild) belonging to a wild group separated from most of the cultivated castor samples from China, India, France, and Jordan. These results suggested that the cultivated castor contains a narrow genetic base. Accordingly, we recommend that wild castor genetic resources be introduced for breeding novel castor varieties. Furthermore, the Vietnam, Malaysia, Indonesia, and Nigeria accessions were clustered into the same group. The results of principal coordinate analysis (PCoA) and UPGMA cluster analysis were consistent with each other. The findings of this study are important for future breeding studies of castor.

Cola Acuminata

Cola species constitute an important non-timber forest product. Besides the food value, Cola is rich in numerous phytochemicals, making it more important for its use in both African traditional medicine and potentials in industrial pharmacopoeia. Knowledge about genetic diversity is essential for conservation. In this paper, we reported genetic variability of Cola acuminata and C. nitida germplasm across the Cola - producing states (the rain forest and derived savannah zones) in Nigeria using Random Amplified Polymorphic DNA (RAPD) markers. Fifteen primers which gives an average of 6.5 bands per primer were selected for both species. C. acuminata exhibited a higher level of variation with 71.5% of the detected markers being polymorphic (223 polymorphic alleles), whereas C. nitida presented 58.3% variation with 182 polymorphicalleles. Inter-population differentiation was measured as Jaccard?s similarity coefficient. The mean similarity index amounted to 42.5% in C. acuminata and 46.7% in C. nitida respectively. Results reveal the genetic structure of both species and conservation strategies are suggested.

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.

Pisang Raja is an important local banana cultivar in the economy and cultural life in Indonesia, especially at Java. There are many Pisang Raja cultivars found on Java Island with various local names in each region, resulted in problems on taxonomic identification and grouping. Conventional research for grouping banana cultivars is still using morphological characters but considered inaccurate because of its subjectivity. This study aims to analyze the genetic diversity, grouping, and genome estimation of 13 local cultivars of Pisang Raja based on molecular approach using RAPD markers (OPA primers 1-20). Clustering and Principal Coordinates Analysis were performed to the amplified products using Paleontological Statistics (PAST) application version 3.15. Results showed that there were 12 primers which successfully amplified and produced DNA polymorphic bands in Pisang Raja, specifically OPA 1, OPA 2, OPA 3, OPA 4, OPA 5, OPA 8, OPA 16, OPA 17, OPA 18, OPA 19, and OPA 20. Pisang Raja cultivars considered have high genetic diversity, indicated by high polymorphic bands (95.17%) and low similarity coefficient values (0.2-0.6). Clustering and PCo analysis resulted in 3 clusters following its genomic group consist of AAA, AAB and ABB genomes, with Pisang Raja Bali as an outgroup (ABB). However, the separation of each cluster for genome inference was unclear. Cluster 1 consists of Pisang Raja Madu (AAB) and Raja Sereh (AAB). Cluster 2 consists of AAA and AAB genomes; includes Pisang Raja Jambe (AAA), Raja Kriyak (AAA), Raja Kutuk (AAB), Raja Brentel (AAB), Raja Seribu (AAB), and Raja Lini (AAB). Cluster 3 consists of AAA and AAB genomes, includes Pisang Raja Kisto (AAA), Raja Delima (AAA), Raja Bandung (AAB) and Raja Gareng (AAB). While Pisang Monyet (AAw) and Klutuk Wulung (BBw) as wild relatives were nested in Cluster 2. There were some different results of genome estimation based on RAPD markers compared to morphological characterization, and other molecular techniques. The use of RAPD markers is quite efficient and effective for studying genetic diversity and identifying genomes in bananas.
