Summary: GeneSupport implements a genome-scale algorithm: Maximum Gene-Support Tree to estimate species tree from gene trees based on multilocus sequences. It provides a new option for multiple genes to infer species tree. It is incorporated into popular phylogentic program: PHYLIP package with the same usage and user interface. It is suitable for phylogenetic methods such as maximum parsimony,...
A biologically realistic method was used to simulate evolutionary trees. The method uses a real DNA coding sequence as the starting point, simulates mutation according to the mutational spectrum of Escherichia coli-including base substitutions, insertions, and deletions-and separates the processes of mutation and selection. Trees of 8, 16, 32, and 64 taxa were simulated with average branch leng...
One of the most important aspect of molecular and computational biology is the reconstruction of evolutionary relationships. The area is well explored after decades of intensive research. Despite this fact there remains a need for good and efficient algorithms that are capable of reconstructing the evolutionary relationship in reasonable time. Since the problem is computationally intractable, e...
Pezizomycotina is the largest subphylum of Ascomycota and includes the vast majority of filamentous, ascoma-producing species. Here we report the results from weighted parsimony, maximum likelihood and Bayesian phylogenetic analyses of five nuclear loci (SSU rDNA, LSU rDNA, RPB1, RPB2 and EF-lalpha) from 191 taxa. Nine of the 10 Pezizomycotina classes currently recognized were represented in th...
The monophyletic status of the genus Massarina was evaluated on the basis of phylogenetic analysis of the partial small subunit gene (SSU), internal transcribed spacers (ITS 1 & 2), and 5.8S gene sequences of the ribosomal DNA. Species of Massarina used in the study clustered into two distinct clades with high bootstrap support in trees generated from maximum parsimony, weighted parsimony, maxi...
In this paper, I argue for the instability of an increasingly popular position about how metaphysicians ought to regard parsimony. This is rooted in unrecognized tension between two claims. First, we as minimize number ontological kinds posit. Second, it not case that ideological expressions employ, especially when those are same kind (e.g. compositional predicates "is a part of" and "overlaps"...
