A chick gene homologous to the Drosophila homeobox gene labial has been cloned and sequenced. Regions of additional sequence identity outside of the homeobox reveal a close relationship to the mouse gene Hox 1.6. Northern blot analysis demonstrates that Ghox-lab and Hox 1.6 transcripts are both present at high levels during early stages of chick and mouse(More)
A novel non-motile, Gram-staining-negative, yellow-pigmented bacterium, designated AG13(T), isolated from a rain water pond at a plant nursery in Spain and characterized as a plant-growth-promoting bacterium, was investigated to determine its taxonomic status. The isolate grew best over a temperature range of 15-40 °C, at pH 5.0-8.0 and with 0-4 % (w/v)(More)
Nucleic acid sequences may be looked upon as words over the alphabet of nucleotides. Naturally occurring DNAs and RNAs form subsets of the set of all possible words. The use of formal languages is proposed to describe the structure of these subsets. Regular languages defined by finite automata are introduced to demonstrate the application of the concept on(More)
The taxonomic position of Pseudomonas sp. B13(T), isolated as a 3-chlorobenzoate-degrading organism and used for several groundbreaking studies on the enzymology and genetics of the degradative pathway for haloaromatic compounds, was studied in detail. The previously performed physiological studies, the detection of ubiquinone Q-9, the polyamine pattern(More)
Two strains, NCCP-650T and NCCP-667, were isolated from industrial effluent and their taxonomic positions were investigated using a polyphasic taxonomic approach. The strains were found to be Gram-stain negative, strictly aerobic, motile short rods, which are tolerant to heavy-metals (Cr+2, As+2, Pb+2 and Cu+2). Cells were observed to grow at a temperature(More)
Principles and guidelines are presented to ensure a solid scientific standard of papers dealing with the taxonomy of taxa of Pasteurellaceae Pohl 1981. The classification of the Pasteurellaceae is in principle based on a polyphasic approach. DNA sequencing of certain genes is very important for defining the borders of a taxon. However, the characteristics(More)
Bacterial isolates obtained from polychlorophenol-contaminated sites in Finland (strain K101(T)) and from a Dutch drinking water well (strain A175(T)) were characterized taxonomically. 16S rRNA gene sequence analysis, determination of DNA G+C content, physiological characterization, estimation of the ubiquinone and polar lipid patterns and fatty acid(More)
A bacterial strain capable of degrading some monochlorinated dibenzofurans, designated RW16T, was isolated from aerobic River Elbe sediments. The strain was characterized based on 16S rRNA gene sequence analysis, DNA G+C content, physiological characteristics, polyamines, ubiquinone and polar lipid pattern and fatty acid composition. This analysis revealed(More)
A novel, Gram-staining-negative, rod-shaped, aerobic and motile bacterium, designated strain CC-SKC2T, was isolated from the root tumor of a green bell pepper (Capsicum annuum var. grossum) plant in Taiwan. Cells were positive for oxidase and catalase activities and exhibited growth at 25–37 °C, pH 4.0–9.0 and tolerated NaCl concentrations up to 4.0 %(More)
