Disruption of morphogenesis and transformation of the suspensor in abnormal suspensor mutants of Arabidopsis
(Company of Biologists, 1994)
The suspensor is the first differentiated structure produced during plant embryogenesis. In most angiosperms, the suspensor functions early in development to provide nutrients and growth regulators to the embryo proper. ...
Constitutive expression of the cloned phenol hydroxylase gene(s) from Alcaligenes eutrophus JMP134 and concomitant trichloroethylene oxidation
(American Society for Microbiology, 1996-09)
Given the demonstrated phenol-dependent trichloroethylene (TCE) degradation in Alcaligenes eutrophus JMP134 (A. R. Harker and Y. Kim, Appl. Environ. Microbiol. 56:1179-1181, 1990), this work represents a purposeful effort ...
Subpicosecond, freely propagating electromagnetic pulse generation and detection using GaAs:As epilayers
(AIP Publishing, 1991-04-08)
Using GaAs epilayers with arsenic precipitates (GaAs:As) as the photoconductive material in a broad-band optoelectronic terahertz beam system, we have generated and detected freely propagating, subpicosecond electromagnetic ...
AlgT (sigma^22) controls alginate production and tolerance to environmental stress in Pseudomonas syringae
(American Society for Microbiology, 1999-12)
Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate, which is a copolymer of D-mannuronic and L-guluronic acids. One of the key regulatory genes controlling alginate biosynthesis ...
Whole-cell kinetics of trichloroethylene degradation by phenol hydroxylase in a Ralstonia eutropha JMP134 derivative
(American Society for Microbiology, 1998-11)
The rate, progress, and limits of trichloroethylene (TCE) degradation by Ralstonia eutropha AEK301/pYK3021 whole cells were examined in the absence of aromatic induction. At TCE concentrations up to 800 uM, degradation ...
Reverse transcriptase PCR amplification of Rickettsia typhi from infected mammalian cells and insect vectors
(American Society for Microbiology, 1998-06)
We developed a reverse transcriptase PCR assay to detect expression of 120- and 17-kDa antigen genes in Rickettsia typhi. Infected Vero cell and flea RNAs were reverse transcribed by using random hexamers. The cDNA was ...
Evaluation of alternative techniques to determine pork carcass value
(American Society of Animal Science, 1992)
Three techniques for estimating the value of pork carcasses were evaluated: an optical probe, a real-time ultrasound scanner, and an electromagnetic scanner (EMSCAN). The ability of these techniques to predict carcass value ...
Application of DNA probes to analysis of bacteriophage distribution patterns in the environment
(American Society for Microbiology, 1992-06)
Radiolabeled bacteriophage DNA probes have been used in this study to determine the distribution of Pseudomonas aeruginosa-infecting bacteriophages in natural samples of lake water, sediment, soil, and sewage. The sensitivity ...
Characterization of the alginate biosynthetic gene cluster in Pseudomonas syringae pv. syringae
(American Society for Microbiology, 1997-07)
Alginate, a copolymer of D-mannuronic acid and L-guluronic acid, is produced by a variety of pseudomonads, including Pseudomonas syringae. Alginate biosynthesis has been most extensively studied in P. aeruginosa, and a ...
Quantitation of Plasmodium falciparum sporozoites transmitted in vitro by experimentally infected Anopheles gambiae and Anopheles stephensi
(American Society of Tropical Medicine and Hygiene, 1991)
The frequency and numbers of Plasmodium falciparum sporozoites transmitted in vitro and corresponding sporozoite loads were determined for experimentally infected Anopheles gambiae and An. stephensi. Geometric mean (GM) ...
