Genetic variability of Paecilomyces variotii isolates causal agent of Die-back disease using rDNA-ITS and RFLP markers
Paecilomyces variotii is one of the most important causal agents of dieback disease in pistachio (Pistacia vera) gardens. The disease affects different parts of the tree, such as branch and trunk. Assessment of genetic structure in different populations of this species will lead to more useful management of pistachio dieback disease. In this study, genetic variation within samples of P. varioti...
متن کاملHuman Food Safety Evaluation of rDNA Biotechnology-Derived Foods
Food manufacturers are required by law to ensure the safety and quality of their products regardless of the source or identity of the ingredients. Traditional foods are viewed by the Food and Drug Administration as “safe” based on a long history of use. The consuming public also views traditional foods as safe. However, many traditional foods contain naturally occurring toxins that can present ...
متن کاملStructure and evolution of human and African ape rDNA pseudogenes.
We discuss the evolutionary significance of four aberrant 18S rDNA clones that were obtained from human, chimpanzee, and gorilla DNA libraries. We show that these clones carry representatives of a small 18S rDNA pseudogene family that arose in a common ancestor of these species. Aspects of their structure and phylogenetic distribution suggest that the 18S pseudogenes no longer interact genetica...
متن کاملIntraspecific and intragenomic variability of ITS rDNA sequences reveals taxonomic problems in Ceratocystis fimbriata sensu stricto.
Fourteen new species in the Latin American Clade (LAC) of the Ceratocystis fimbriata complex recently were distinguished from C. fimbriata sensu stricto largely based on variation in ITS rDNA sequences. Among the 116 isolates representing the LAC, there were 41 ITS haplotypes. Maximum parsimony (MP) analysis of ITS sequences produced poorly resolved trees. In contrast, analyses of mating-type g...
متن کاملFurther evidence for the variability of the 18S rDNA loci in the family Tingidae (Hemiptera, Heteroptera)
As of now, within the lace bug family Tingidae (Cimicomorpha), only 1.5% of the species described have been cytogenetically studied. In this paper, male karyotypes of Stephanitis caucasica, Stephanitis pyri, Physatocheila confinis, Lasiacantha capucina, Dictyla rotundata and Dictyla echii were studied using FISH mapping with an 18S rDNA marker. The results show variability: the major rDNA sites...
