Pyrophosphatase is essential for growth of Escherichia coli.
The ppa gene for inorganic pyrophosphatase is essential for the growth of Escherichia coli. A recombinant with a chromosomal ppa::Kanr lesion and a temperature-sensitive replicon with a ppa+ geneExpand
Amphidiploid Induction from Diploid Rose Interspecific Hybrids
Although the effect of colchicine treatment varied some among interspecific hybrids, 2.50 mmol for 48 h of node agitation or 1.25 mmol for at least 5 d of shoot culture were optimal and confirmed the transfer of disease resistance from wild diploid Rosa species to modern rose cultivars. Expand
Influence of Chemical Oxidant on Degradation of Benzo[a]Pyrene Metabolites by the Bacterium-Zoogloea sp.
It is neither comprehensive nor appropriate that the bioremediation of a benzo[a] pyrene (BaP)-contaminated environment be assessed only by its high degradation extent because its metabolites'Expand
Sexual dimorphism of adult labial palps of the peach fruit moth Carposina sasakii Matsumura (Lepidoptera: Carposinidae) with notes on their sensilla
The labial palps and their sensilla of the peach fruit moth Carposina sasakii Matsumura, a serious pest of pome fruits in eastern Asia, were investigated using light microscopy and scanning andExpand
Occurrence of N-formylkynurenine in extracts of Neurospora crassa: evidence for the activity of tryptophan pyrrolase.
The occurrence of N-formylkynurenine in extracts of tryptophan-grown Neurospora is interpreted as direct evidence for the activity of tryPTophan pyrrolase in this organism. Expand
Isolation and characterization of a dinucleoside triphosphatase from Saccharomyces cerevisiae.
An enzyme able to cleave dinucleoside triphosphates has been purified 3,750-fold from Saccharomyces cerevisiae and indicates that this enzyme is different from the mRNA decapping enzyme previously characterized. Expand
Drug interactions I: detection of inorganic nitrite in organic nitrate esters under acidic conditions simulating the human stomach.
It is found that nitrate ion is not reduced to nitrite by hydrochloric acid (pH 1-3), and no evidence for nitrite contamination or generation by pentaerythritol tetranitrate was found. Expand
Research progresses of artificial nucleic acid cleavage agents
Artificial nucleic acid cleavage agents have attracted close attention because they play important roles in biochemistry and molecular biology. According to the cleavage mechanism of nucleic acid,Expand
Production of eicosapentaenoic acid (EPA, 20:5n-3) in maize (Zea mays L.) through the alternative ∆8 desaturation pathway mediated by particle bombardment
The data demonstrate the feasibility for the heterologous production of EPA in maize and this will lay a foundation for the production of VLCPUFAs, including EPA and DHA, in maize by metabolic engineering in the future. Expand
