Limitations And Potentials Of Current Motif Discovery Algorithms, Jianjun Hu, Bin Li, D. Kihara Jan 2005

Limitations And Potentials Of Current Motif Discovery Algorithms, Jianjun Hu, Bin Li, D. Kihara

Computational methods for de novo identification of gene regulation elements, such as transcription factor binding sites, have proved to be useful for deciphering genetic regulatory networks. However, despite the availability of a large number of algorithms, their strengths and weaknesses are not sufficiently understood. Here, we designed a comprehensive set of performance measures and benchmarked five modern sequence-based motif discovery algorithms using large datasets generated from Escherichia coli RegulonDB. Factors that affect the prediction accuracy, scalability and reliability are characterized. It is revealed that the nucleotide and the binding site level accuracy are very low, while the motif level accuracy …

The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative effort among several plant databases and experts in plant systematics, botany and genomics. A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These provide a network of vocabularies linked by relationships (ontology) to facilitate queries that cut across datasets within a database or between multiple databases. The current version of the ontology integrates diverse vocabularies used to describe Arabidopsis, maize and rice (Oryza sp.) anatomy, morphology and growth stages. Using the ontology browser, …


Poor Taxon Sampling, Poor Character Sampling, And Non-Repeatable Analyses Of A Contrived Dataset Do Not Provide A More Credible Estimate Of Insect Phylogeny: A Reply To Kjer., T. Heath Ogden Dec 2004

Poor Taxon Sampling, Poor Character Sampling, And Non-Repeatable Analyses Of A Contrived Dataset Do Not Provide A More Credible Estimate Of Insect Phylogeny: A Reply To Kjer., T. Heath Ogden

T. Heath Ogden

The wealth of data available for phylogenetic analysis of the insect orders, from both morphological and molecular sources, is steadily increasing. However, controversy exists among the methodologies one can use to reconstruct ordinal relationships. Recently, Kjer (2004) presented an analysis of insect ordinal relationships based exclusively on a single source of information: 18S rDNA sequence data. Kjer claims that his analysis resulted in a more ‘‘credible’’ phylogeny for the insect orders and strongly criticized our previous phylogenetic results. However, Kjer only used a subset of the data that are currently available for insect ordinal phylogeny, misrepresented our analyses, and omitted …


Phylogeny Of Ephemeroptera (Mayflies) Based On Molecular Evidence, T. Heath Ogden Dec 2004

Phylogeny Of Ephemeroptera (Mayflies) Based On Molecular Evidence, T. Heath Ogden

T. Heath Ogden

This study represents the Wrst molecular phylogeny for the Order Ephemeroptera. The analyses included 31 of the 37 families, representing »24% of the genera. Fifteen families were supported as being monophyletic, Wve families were supported as nonmonophyletic, and 11 families were only represented by one species, and monophyly was not testable. The suborders Furcatergalia and Carapacea were supported as monophyletic while Setisura and Pisciforma were not supported as monophyletic. The superfamilies Ephemerelloidea and Caenoidea were supported as monophyletic while Baetoidea, Siphlonuroidea, Ephemeroidea, and Heptagenioidea were not. Baetidae was recovered as sister to the remaining clades. The mayXy gill to wing …
