We characterized five transposable elements from fish: one from zebrafish (Brachydanio rerio), one from rainbow trout (Salmo gairdneri), and three from Atlantic salmon (Salmo salar). All are closely similar in structure to the Tc1 transposon of the nematode Caenorhabditis elegans. A comparison of 17 Tc1-like transposons from species representing three phyla(More)
Newborns are less able to concentrate urine than adults are. With development of the concentrating system and a hypertonic medullary interstitium, there is a need to generate intracellular osmolytes such as sorbitol, which is produced in a reaction catalyzed by the enzyme aldose reductase. We sought to discriminate between two possible mechanisms of aldose(More)
Bacterial acetyl-coenzyme A carboxylase (ACCase) is a multicomponent system composed of AccA, AccD, AccC, and AccB (also known as BCCP), which is required for fatty acid biosynthesis. It is essential for cell growth and has been chemically validated as a target for antimicrobial drug discovery. To identify ACCase inhibitors, a simple and robust assay that(More)
The 1.6 kb Tc1 transposable element of Caenorhabditis elegans undergoes excision and transposition in the germline. In somatic tissue it is excised at high frequency. Extrachromosomal linear and circular copies of Tc1 have been identified that are likely to be products of somatic and germline excision. In the present study, we have determined the sequences(More)
Restriction fragment patterns of mitochondrial DNA from sibling species of cyst nematodes Heterodera glycines and H. schachtii were examined. Fourteen restriction endonucleases recognizing four, five, and six base-pair sequences yielded a total of 90 scorable fragments of which 10% were shared by both species. Mitochondrial genome sizes for H. glycines and(More)
Twelve populations of Heterodera glycines from the United States (8), China (2), Japan (1), and Colombia (1) were surveyed for phenotypic intraspecific variability in 42 enzyme systems. Activity of 20 enzymes was detected following isoelectric focusing in polyacrylamide gels of extracts from mass homogenates and single females. Five enzymes, aspartate(More)
Punctodera punctata completed its life cycle on Poa annua (annual bluegrass), P. pratensis (Merion Kentucky bluegrass), Lolium perenne (perennial ryegrass), and Festuca rubra rubra (spreading fescue). Minimum time for completion of a life cycle from second-stage juvenile to mature brown cyst was 40 days at 22-28 C. Inoculation by single juveniles indicated(More)
