We also propose a normalization to fix the traditional additive phylogenetic similarity and differentiation measures, and we show that this yields the same similarity and differentiation measures we derived from multiplicative phylogenetic diversity partitioning. We thus can achieve a consensus on ...
The genetic interrelationships among these strains were determined by pattern similarity coefficients, which coincided with delineations by phylogenetic analysis. This study also revealed two heterogeneous spc operons present in the phytoplasma clade. This latter finding may have significant implications for ...
The protein sequences are treated as categorical time series, and a measure of similarity between a pair of sequences, the spectral covariance, is based on the common periodicity between these two sequences. Unlike the other methods, the spectral covariance method focuses on the relationship ...
Juglans26,27. If cross-species gene flow (introgression) has influenced large portions of related genomes, phylogenetic inference based on DNA-sequence alignments will produce species trees that reflect the reticulation history rather than the
Further analysis of the structure of the isolated clone revealed that it contains two glutaminase (PAG) sequences of 134 and 95 nucleotides long, respectively, separated by a segment of 142 nucleotides without any significant similarity to the database. The clone starts at the 5'-end with an ...
Summary: We propose structural similarity of two melodies based on sub-trees from the time-span tree provided by the generative theory of tonal music. The structural distance of the tree was previously defined and called the "maximal time-span distance", and experimental results showed to some ...
Phylogenetic analyses showed the significant divergence between Amu Darya and Syr Darya freshwater sturgeons and supported the monophyletic origin of the Pseudoscaphirhynchus species. We confirmed that two sympatric Amu Darya species P. kaufmanni and P. hermanni form a single genetic cluster, which ...
The genetic variability and phylogenetic relationships in oil palm (Elaeis guineensis Jacq.) were studied using RAPD (Random Amplified Polymorphic DNA). Leaf samples of 151 plants were collected from different areas in southern Thailand. DNA from the leaf samples was isolated using CTAB buffer and ...
The phylogeny of 12 species and reference strains of and was studied based on partial 593-bp gene sequences. The topology of the phylogenetic neighbor-joining tree based on the gene was similar to that of the tree based on the 16S rRNA gene. However, was found to provide a better resoluti...
Based on the alignment of amino acid sequences of plant NADP-MEs, we identify putative binding sites for the substrates and analyze the phylogenetic ... MF Drincovich,P Casati,CS Andreo - 《Febs Letters》 被引量: 545发表: 2001年 Structural and evolutionary classification of Type II restriction...
