evolutionary origin and phylogenetic relationships among fusarium oxysporum f. sp. melonis isolates in iran and their relationship with nonpathogenic isolates
پژمردگی فوزاریومی خربزه و طالبی با عامل fusarium oxysporum f. sp. melonis از بیماری های مهم قارچی در مناطق رشد این گیاهان می باشد. جدایه های f. oxysporum از گیاهان و خاک ریزوسفر متعلق به پنج استان مهم تولیدکننده ی خربزه و طالبی جداسازی شد و بر پایه ی بیماری زایی در ارقام افتراقی، گروه های سازگاری رویشی (vegetative compatibility groups)، توالی سنجی ناحیه ی جداکننده ی بین ژنی دی اِن اِی ریبوزومی (n...
15 صفحه اولA new balance index for phylogenetic trees
Several indices that measure the degree of balance of a rooted phylogenetic tree have been proposed so far in the literature. In this work we define and study a new index of this kind, which we call the total cophenetic index: the sum, over all pairs of different leaves, of the depth of their lowest common ancestor. This index makes sense for arbitrary trees, can be computed in linear time and ...
متن کاملQuantitative Comparison of Tree Pairs Resulted from Gene and Protein Phylogenetic Trees for Sulfite Reductase Flavoprotein Alpha-Component and 5S rRNA and Taxonomic Trees in Selected Bacterial Species
Introduction: FAD is the cofactor of FAD-FR protein family. Sulfite reductase flavoprotein alpha-component is one of the main enzymes of this family. Based on applications of this enzyme in biotechnology and industry, it was chosen as the subject of evolutionary studies in 19 specific species. Method: Gene and protein sequences of sulfite reductase flavoprotein alpha-component, 5S rRNA sequence...

متن کاملLimit theorems for patterns in phylogenetic trees.
Studying the shape of phylogenetic trees under different random models is an important issue in evolutionary biology. In this paper, we propose a general framework for deriving detailed statistical results for patterns in phylogenetic trees under the Yule-Harding model and the uniform model, two of the most fundamental random models considered in phylogenetics. Our framework will unify several ...
