Bemisia tabaci (Hemiptera: Aleyrodidae) consists of a complex of morphologically indistinct biotypes that vary mainly in their capacity to transmit plant viruses and to induce physiological disorders in plants of economic importance. The adaptability of B. tabaci to many regions of the world has fostered the appearance of various biotypes and has resulted in a broad spectrum of ... more

Clonal reproduction; Genetic diversity; Pitcairnia albiflos; RAPD markers

Pitcairnia albiflos is a Bromeliaceae species endemic to Brazil that has been included as data-deficient in the extinction risk list of Brazilian flora. We analyzed genetic variability in P. albiflos populations using RAPD markers to investigate population structure and reproductive mechanisms and also to evaluate the actual extinction risk level of this species. Leaves of 56 ... more

Brazilian Atlantic forest; Cebus; Genetic diversity; Management programs

The yellow-breasted capuchin monkey, Cebus xanthosternos, is one of the most endangered species of the Brazilian Atlantic Forest. In situ conservation for this species is problematic due to habitat destruction; therefore, captive conservation has been considered as an alternative strategy. A Studbook for C. xanthosternos has been kept for more than 20 years; ... more

Estimations of genetic diversity and of relationships between varieties are crucial for cotton breeding. The genetic diversity of 59 core cotton cultivars, most of which were collected from China’s main cotton-growing areas, was analyzed based on genomic and newly developed expressed sequence tag-derived microsatellite markers, using total DNA extracted from fresh leaf tissue. Three ... more

Clustering; Genetic correlation; Genetic diversity; Heritability; Oil content

Jatropha curcas, internationally and locally known, respectively, as physic nut and pinhão manso, is a highly promising species for biodiesel production in Brazil and other countries in the tropics. It is rustic, grows in warm regions and is easily cultivated. These characteristics and high-quality oil yields from the seeds have made this plant a priority for biodiesel programs ... more

Devil stinger; Genetic diversity; Inimicus japonicus; Microsatellite DNA

Inimicus japonicus, the devil stinger, has an extensive distribution along the coast of China, Japan and the Korean Peninsula. Nineteen highly polymorphic microsatellite markers were isolated and characterized in I. japonicus. Twenty-eight individuals from a wild population were tested for polymorphism using this set of polymorphic microsatellite markers. The number of ... more

Genetic diversity; Microsatellites; SSR markers; Wild sweet cherry

Wild sweet cherry (Prunus avium) trees are abundant in the northern part of Turkey, including the Coruh Valley. We analyzed 18 wild sweet cherry genotypes collected from diverse environments in the upper Coruh Valley in Turkey to determine genetic variation, using 10 SSR primers. These SSR primers generated 46 alleles; the number of alleles per primer ranged from 3 to 7, with a ... more

D-loop; Genetic diversity; Mitochondrial gene; Persian Gulf; Phylogenetic analysis; Sea turtles

Genetic diversity of sea turtles (hawksbill turtle) was studied using sequencing of mitochondrial DNA (mtDNA, D-loop region). Thirty dead embryos were collected from the Kish and Qeshm Islands in the Persian Gulf. Analysis of sequence variation over 890 bp of the mtDNA control region revealed five haplotypes among 30 individuals. This is the first time that Iranian haplotypes have been ... more

Resistance gene analog-expressed sequence tag (RGA-EST)-based markers have been used for variety discrimination and studies of genetic diversity in wheat. Our aim is to increase the competitiveness of public wheat breeding programs through intensive use of modern selection technologies, mainly marker-assisted selection. The genetic diversity of 77 wheat nucleotide binding site (NBS)- ... more

Flooding; Genetic diversity; tolerance; Uplands

Saplings of Aegiphila sellowiana were submitted to flooding and analysis of genetic diversity in order to investigate flooding tolerance as well as its genetic determination. This response is important because it means that some lines could be planted in degraded riparian areas. Leaves were sampled from each plant, and they were submitted to different flooding periods. Mortality ... more
