The bootstrapping method of determining confidence in the topology of phylogenetic trees has been applied to electrophoretic protein data for two groups of amphibians: salamanders of two North American genera (Aneides and Plethodon) of the tribe Plethodontini and Holarctic hylid frogs. Some current methods of phylogenetic reconstruction for electrophoretic protein data have been evaluated by co...

In this paper, we introduce a new phylogenetic tree algorithm that generates phylogenetic trees by repeatedly inserting species one-by-one. The incremental phylogenetic tree algorithm can work on proteins or DNA sequences. Computer experiments show that the new algorithm is better than the commonly used UPGMA and Neighbor Joining algorithms. Keywords—Data structure, Distance matrix, Phylogeneti...

In this work, isozyme and agromorphological variability of radio-induced rice mutants with different cytoplasm bases was surveyed. Agromorphological data (plant type, lodging resistance, maturity and yield) were transformed into binary data. These markers, along with isozyme (Peroxidases, Esterases, Catalases, Alcohol Dehydrogenases and Polyphenoloxidases) data, were considered for genetic dive...

Metagenomic approaches provide access to the genetic diversity of environment for biotechnological applications, allowing discovery new enzymes and pathways numerous catalytic processes. Five putative type II CRISPR-Cas9 DNA endonucleases were identified from compost community using DELTA-BLAST algorithm. It was determined phylogenetic UPGMA analysis that four these potential are similar those ...

the aim of the present study was to find the best or optimum topology of six chicken populations, which were genotyped based on nine highly polymorphic microsatellite markers. to reach this goal, different genetic distances based on infinite allele model (iam), stepwise mutation model (smm) and drawing phylogentic trees on un-weighted pair-group method using arithmetic averages (upgma) method w...

O objetivo desse trabalho foi determinar descritores morfológicos de acessos curauá através caracteres visando à avaliação dos germoplasmas, na Embrapa Amazônia Oriental, em Belém, PA. Foram estudados sete quantitativos 42 curauá, totalizando 210 indivíduos, conservados in vivo no Horto Plantas Medicinais. Os dados foram submetidos as analises multivariadas, realizado a seleção direta e com rea...

Terminal restriction fragment length polymorphism (T-RFLP) is a culture-independent method of obtaining a genetic fingerprint of the composition of a microbial community. Comparisons of the utility of different methods of (i) including peaks, (ii) computing the difference (or distance) between profiles, and (iii) performing statistical analysis were made by using replicated profiles of eubacter...

The number of experiments that allows the choice parents to be used in controlled crossings a more assertive way cluster analysis is unknown for plant architecture and grain yield traits common bean. Therefore, objective this work was determine should considered Tocher's unweighted pair group method with arithmetic mean (UPGMA) analyses identify promising bean several traits. Four were carried ...

We introduce the idea of constructing hypothetical evolutionary trees using an incremental algorithm that inserts species one-by-one into the current evolutionary tree. The method of incremental phylogenetics by repeated insertions lead to an algorithm that can be used on DNA, RNA and amino acid sequences. According to experimental results on both synthetic and biological data, the new algorith...
