Selected Subset

Anatolia played an important role in the diversification and spread of economically important Vitis vinifera varieties. Although several biodiversity studies have been conducted with local cultivars in different regions of Anatolia, our aim is to gain a better knowledge on the biodiversity of endangered historical V. vinifera varieties in the northern Adana region of southern Anatolia, particularly those potentially displaying viticulture characteristics. We also demonstrate the genetic relatedness in a selected subset of widely cultivated and commercialized V. vinifera collection cultivars, which were obtained from the National Grapevine Germplasm located at the Institute of Viticulture, Turkey. In the present study, microsatellites were used in narrowing the sample size from 72 accessions down to a collection of 27 varieties. Amplified fragment length polymorphisms were then employed to determine genetic relatedness among this collection and local V. vinifera cultivars. The unweighted pair group method with arithmetic mean cluster and principal component analyses revealed that Saimbeyli local cultivars form a distinct group, which is distantly related to a selected subset of V. vinifera collection varieties from all over Turkey. To our knowledge, this is the first study conducted with these cultivars. Further preservation and use of these potential viticultural varieties will be helpful to avoid genetic erosion and to promote continued agriculture in the region.

Wild Accessions

Chrysanthemums have beautiful flowers with high ornamental value and rich genetic diversity. Amplified fragment length polymorphism (AFLP) markers were used to detect the relationships among 12 wild accessions and 62 groundcover chrysanthemum cultivars. Nineteen EcoRI/MseI primer combinations revealed 452 informative polymorphic bands with a mean of 23.8 bands and 71.5% polymorphic rate per primer pair. Jaccard’s coefficient of similarity varied from 0.64 to 0.89, indicating much genetic variation in chrysanthemums. The 74 accessions were classified into two major groups by unweighted pair group method with the arithmetic averages (UPGMA). The dendrogram showed that AFLP variability was closely correlated with both geographic distribution and traditional classification of the wild accessions. Among all accessions, genetic relationship was the most relevant factor in AFLP-marker clustering, whereas petal type was also informative. AFLP technology could be very efficient for discriminating species of chrysanthemum and its related genera and reconstruct their genetic relatedness.

AbstractThe molecular epidemiology of Candida albicans infections in animals has been rarely studied. In this study, multilocus sequence typing was used to characterise the genetic diversity and population structure of 24 avian origin C. albicans isolates collected from different birds with candidiasis and compared to human isolates. Fourteen diploid sequence types (DSTs) including six new DSTs were determined. Cluster analysis revealed that isolates grouped into 8 clades. Bird isolates mainly belonged to minor clades and Clade 15 with DST 172 was the most common (11 isolates; 45.8%). The remaining isolates were clustered into Clade 7 (5 isolates; 20.8%), Clade 10 (4 isolates; 16.6%), Clade 8 (2 isolates; 8.3%), Clade 4 (1 isolate; 4.2%) and Clade 16 (1 isolate; 4.2%). Unweighted pair group method with arithmetic averages (UPGMA) and eBURST analyses showed that the genetic construction of avian origin C. albicans population is fairly diverse. Although species-specific lineages were not found, some degree of separation in the evolution of bird and human strains could be observed.

The Kanab ambersnail (Oxyloma haydeni kanabensis) is a federally endangered mollusc currently known to reside in two locations in the southwestern U.S.A. To determine the extent of within- and between-population genetic variation of this taxon, the amplified fragment length polymorphism (AFLP) technique was used to generate 110 genetic markers among individuals sampled from the two Kanab ambersnail populations and from the only two known southwestern populations of the Niobrara ambersnail (Oxyloma haydeni haydeni) in Utah and northern Arizona. Additional information was obtained from sequence data of cytochrome b and cytochrome oxidase I gene fragments. Results suggest high levels of differentiation among populations, as evidenced through the application of UPGMA (unweighted pair-group method with arthimetic averaging) clustering, F statistics, and Fisher's exact test. Various levels of within-population genetic diversity were observed among populations. Expected heterozygosities ranged from 0.239 to 0.086 under a model assuming Hardy-Weinberg genotypic proportions and ranged from 0.205 to 0.061 under an obligate-selfing completely homozygous model. Results from cluster analyses showed that one Kanab ambersnail population and one Niobrara ambersnail population were more similar than the two Kanab ambersnail populations studied (supported by >80% of bootstrap replicates). These findings were further supported through the phylogenetic analysis of both mito chondrial gene fragments. The data suggest that taxonomic designations need revision, an act that will likely affect the protected status of some of the populations.

Two species of Chamaecyparis and six cultivars each of Juniperus chinensis L. and Juniperus scopulorum Sarg. (Cupressaceae) were subjected to random amplified polymorphic DNA (RAPD) analysis using seven primers. Unweighted pair group method with averages (UPGMA) and principal component analyses of genetic distances between cultivars showed that 42 polymorphic RAPD bands could distinguish among all cultivars and properly group them by species and genera. Where the origin of a specific juniper cultivar is uncertain, analysis of genetic distance can pinpoint close relatives. For example, we were unable to trace the origin of J. chinensis 'Alps', and we initially thought it was a mislabeled J. chinensis 'Blue Alps'. However, we found 'Alps' to be closer to J. chinensis 'Fairview' and 'Mountbatten' than to 'Blue Alps'. Similarly, 'Wichita Blue' has an unknown origin, but it had the highest genetic similarity with 'Medora'.Key words: juniper, cedar, RAPD, cultivars, phylogenetics.

Individuals in most countries around the world drink tea (Camellia sinensis). Tea drinking has attained ceremonial status in many places as a social and medicinal beverage. Although tea is of great importance in Turkey's economy, little is known about the pattern of genetic variation among the various tea genotypes grown in Turkey. A total of 32 tea genotypes found at the Ataturk Tea and Horticulture Research Institute in the eastern Black Sea region of Turkey were sampled. Fluorescent dye amplified fragment length polymorphism (AFLP) markers and capillary electrophoresis were applied for molecular characterization. The AFLP analysis with six primer combinations generated 835 fragments of which 567 were polymorphic, corresponding to 69.8% polymorphism. Resolving powers of the AFLP primers ranged from 62.6 to 81.9, yielding a total of 437.8; the polymorphic information content (PIC) ranged from 0.76 to 0.83, with an average of 0.79. Genetic similarity values ranged from 0.68 to 0.92, with an average of 0.76. The dendrogram derived by unweighted pair group method with arithmetic mean algorithm (UPGMA) and principal coordinate analysis (PCoA) revealed that all tea genotypes could be clearly divided into four distinct clusters. The results of this study will provide valuable information to the tea cultivar breeding program for the purpose of parental selection.

Identificaram-se parentais e híbridos entre Vitis vinifera (videiras comuns) e V. rotundifolia (muscadínias), utilizando-se o polimorfismo enzimático e marcador RAPD (Random Amplified Polymorphic DNA). Os sistemas GOT (glutamato-oxalo-acetato-transaminase), IDH (isocitrato desidrogenase) e PGI (fosfoglucose isomerase) diferenciaram a muscadínia, sendo observadas cinco aloenzimas para o GOT, duas para o LAP (leucina aminopeptidase) e quatro para o EST (esterase). Os sistemas PGI e IDH apresentaram-se como diméricos com o fenótipo de quatro aloenzimas em duas regiões e três em uma região respectivamente. O marcador RAPD apresentou polimorfismo que permitiu a diferenciação entre todos os cultivares. Os dendrogramas UPGMA (unweighted pair-group method with aritmetic mean) obtidos pelas isoenzimas e pelo marcador RAPD foram semelhantes, sendo a aproximação mais forte entre 'Itália' e 'Rubi' que se ligaram aos cultivares Patrícia e A Dona. Os cultivares Piratininga e Eugênio, também bastante próximos, foram os seguintes a se ligarem às demais viníferas. Pelo polimorfismo enzimático e marcador RAPD, a muscadínia ficou bastante isolada dos outros grupos. Pelo método RAPD, aplicado às muscadínias, ao híbrido da Carolina do Norte NC66 C203-9, a um possível híbrido e seu parental feminino, observou-se o seguinte: os híbridos foram intermediários às muscadínias e viníferas, porém o possível híbrido se assemelhou ao parental feminino, enquanto o NC66203-9 apresentou bandas provenientes das muscadínias e viníferas, comprovando sua origem híbrida.

In The Beginning

Pawpaw [Asimina triloba (L.) Dunal.], a tree fruit native to eastern North America, is in the beginning stages of commercialization. Cultivars available in the early 20th century have been lost, and significant genetic erosion may have occurred. Polymorphic microsatellite marker loci were developed from enriched genomic libraries. Five marker loci were used to fingerprint 28 cultivars and 13 selections. For the 41 genotypes, 102 alleles were amplified and major allele frequency (0.16–0.94), number of genotypes (2–27), and allele size (144–343 bp) varied greatly by locus. Four loci were highly polymorphic, as indicated by values for expected heterozygosity (He), observed heterozygosity (Ho), and polymorphism information content, but only two alleles were detected at locus Pp-C104. A high level of genetic diversity was observed in the studied genotypes. The Ho (0.68) and He (0.70) were similar and indicated few null alleles. In the 41 genotypes, 39 unique fingerprints were observed. These new microsatellite marker loci will be useful for cultivar fingerprinting, management of collections, and investigation of genetic diversity in collections and wild populations. Grouping of genotypes in an unweighted pair group method with arithmetic mean dendrogram was generally consistent with their origins.

Varroa destructor is a major ectoparasitic mite which feeds on the western honey bee, Apis mellifera hemolymph. Morphometric analysis of V. destructor in Iran was performed in order to detect differences within some populations of the species. Totally, 145 female mites were collected from A. mellifera colonies in different geographical regions in Iran and Europe (Spain and France). Eight morphological variables were measured: 1) length of dorsal shield (LDS), 2) width of dorsal shield (WDS), 3) length of genital shield (LGS), 4) width of genital shield (WGS), 5) length of metapodal shield (LMS), 6) width of metapodal shield (WMS), 7) length of anal shield (LAS) and 8) width of the anal shield (WAS). The ratios of LDS/WDS, WDS/LDS, LGS/WGS and LAS/WAS were also calculated. Multivariate analyses demonstrated significant differences in means of body length (LDS) and body width (WDS) between populations. Using principal component analysis (PCA) and cluster analysis with pair group method, five morphological groups were established. PCA analyses were also shown one morphotype, A3, between samples. Collectively, our findings suggest a wide phenotypic plasticity within the populations of Varroa mite in Iran.

The information on germplasm diversity and genetic relatedness among elite breeding materials is an important element in maize breeding. Molecular characterization and genetic relationship of 11 QPM-DMR lines were analysed using thirty three SSRs markers. Genetic relationship was determined using Jaccard’s similarity coefficient, and dendogram was then constructed based on the unweighted pair-group method with arithmetical averages (UPGMA). Result showed that (i) all SSRs loci were informative for describing the genotypic variation as showed by their PIC, which ranged from 0.19 for umc1304 to 0.93 for phi112; (ii) the eleven maize inbred lines were clustered into one major group A and small groups B and C that corresponds well with the breeding programs adopted at different institutes of release, and (iii) thus, SSRs marker system is a valuable marker for varietals identification and for genetic diversity study of elite breeding materials.

Summary   Genetic similarity among ten rubber clones originating from the Wickham collection was studied by Amplified Fragment Length Polymorphism (AFLP) markers.  These clones have different levels of resistance to Corynespora cassiicola, one of the major pathogens in rubber plantations.  The information resulted from this study will be used to determine resistant and susceptible clones which will be used in expression study of the genes encoding plant resistance to C. cassiicola.  Genetic similarity values of clones were calculated from all AFLP markers and used to produce a dendrogram using Unweight Pair-Group Method Arithmetic (UPGMA) based on Numerical Taxonomy and Multivariate System (NTSYS) version  1.8 pc.  A total of 481 fragments were detected by using ten pairs of selective AFLP primers, and 233 fragments (48,4 %) of them were polymorphic.  The results clearly demonstrated that genetic background of these ten clones were 85.5% similar.  At 88.0% similarity level, the clones could be divided into three clusters.  Genetic similarity of IRR 100 (resistant clone) with RRIC 103, PPN 2444 and IAN 873 (susceptible clones) was 90.5, 89.5 and 89.0% respectively, while genetic similarity of other three resistant clones (AVROS 2037, PR 255 and BPM 1) to those susceptible clones was 88.0%.  The lowest genetic similarity (85.5%) was found between RRIC 100 (resistant clone) and those three susceptible clones. By considering the distribution and the source of clones, AVROS 2037 (resistant) and PPN 2444 (susceptible) clones which have 88.0% genetic similarity  will finally  be selected for the expression study of the genes.  Kemiripan genetik sepuluh klon karet yang berasal dari koleksi Wickham dipelajari dengan menggunakan marka Amplified Fragment Length Polymorphism (AFLP).  Kesepuluh klon tersebut memiliki tingkat resistensi berbeda terhadap Corynespora cassiicola, salah satu cendawan patogen penting pada daun tanaman karet.
