The genomes of Chrysoporthe austroafricana, Diplodia scrobiculata, Fusarium nygami, Leptographium lundbergii, Limonomyces culmigenus, Stagonosporopsis tanaceti, and Thielaviopsis punctulata are presented in this genome announcement. These seven genomes are from endophytes, plant pathogens and economically important fungal species. The genome sizes range(More)
The specific activity of glutamine synthetase (E.C. of Lemna minor L. is markedly reduced when either ammonium ions or glutamine are present in the growth medium. Combinations of 5 mM ammonia and 5 mM glutamic acid or 5 mM ammonia and 5 mM glutamine as nitrogen source, lead to a 4–5 fold reduction of the maximum activity measurable on 5 mM(More)
Lemna minor has the potential to assimilate ammonia via either the glutamine or glutamate pathways. A 3-4 fold variation in the level of ferredoxindependent glutamate synthase may occur, when plants are grown on different nitrogen sources, but these changes show no simple relationship to changes in the endogenous pool of glutamate. High activities of(More)
Identification of bacterial and archaeal counterparts to eukaryotic ion channels has greatly facilitated studies of structural biophysics of the channels. Often, searches based only on sequence alignment tools are inadequate for discovering such distant bacterial and archaeal counterparts. We address the discovery of bacterial and archaeal members of the(More)
Voltage-gated and ligand-gated ion channels are used in eukaryotic organisms for the purpose of electrochemical signaling. There are prokaryotic homologues to major eukaryotic channels of these sorts, including voltage-gated sodium, potassium, and calcium channels, Ach-receptor and glutamate-receptor channels. The prokaryotic homologues have been less well(More)
Traditionally, bioinformatics has been organized around the concepts of genes and gene products, typically proteins. Proteins are represented as sequences of amino acids and are analyzed against each other by alignment and similarity of their amino acids. However proteins contain subsequences that define their activity and mode of regulation. These(More)
It has been recently demonstrated that the understanding of gene interactions, gene function and ultimately gene and organism evolutionary processes, is facilitated by determination of relationships among the constituent "domains" and "motifs." This understanding, however, comes at the expense of substantial computation necessary to support the required(More)
Protein evolution proceeds by two distinct processes: 1) individual mutation and selection for adaptive mutations and 2) rearrangement of entire domains within proteins into novel combinations, producing new protein families that combine functional properties in ways that previously did not exist. Domain rearrangement poses a challenge to sequence(More)
The MotifNetwork system is a high performance system for the fast scanning and interpretation of large numbers of proteins into their constituent domains. Once transformed into a domain dataset, several levels of analysis such as domaindomain and protein-protein co-location graphs are constructed. These basic data products form the beginning of a(More)
