avena/ニコチン

The pharmacology of Avena sativa has been investigated in laboratory animals following a report that tincture of Avena sativa reduced the craying for cigarettes in man. The tincture, evaporated to dryness, craving for cigarettes in man. The tincture, evaporated to dryness, re-constituted in an equal

The effects of tabtoxinine-beta-lactam (T-beta-L) on nitrate uptake and glutamine synthetase (GS) and nitrate reductase (NR) activities in roots of Avena sativa seedlings were determined. Seven-day-old oat seedlings placed in a 10 mm KNO(3) and 0.5 mm T-beta-L solution for 24 hours took up T-beta-L

Four independent kinds of observations indicate that the cell wall regenerated by oat (Avena sativa L.) and corn (Zea mays L.) protoplasts in culture is less well developed than that regenerated by tobacco (Nicotiana tabacum L.) protoplasts. Following wall regeneration the cereal protoplasts

We have used a highly sensitive immunological tissue print technique to study cell- and tissue-specific expression of heterologous genes in transgenic plants. Primary polyclonal antibodies, raised against legumin of faba bean (Vicia faba L.) and 12S globulin of oat (Avena sativa L.) were used to

1. 6-Hydroxykynurenic acid (4,6-dihydroxyquinoline-2-carboxylic acid, 6-HKA) was isolated in crystalline form from both green and cured tobacco leaves. 2. A method for the determination of 6-HKA by paper chromatography and fluorimetry is described. 3. The content of 6-HKA in the flowers, stem and

Nicotine is a major pharmacologically active component of cigarette smoke. Excessive cigarette smoking is harmful to lung. Sejin-Eum (SJE) I is composed of various Oriental medicines, and SJE II is SJE I plus seeds of Avena sativa (Gramineae) that reduces the craving for cigarette in man. In this

Auxin and auxin-inhibitors from acidic ether extracts of normal stem tissue of Nicotiana longiflora, N. debneyi-tabacum, their tumor producing F 1 hybrid and non-tumor and tumor-prone segregants were separated by thin-layer chromatography and measured by an Avena curvature test. A significantly

Auxin and auxin-inhibitors from acidic ether extracts of normal Nicotiana stem tissues of N. glauca and N. langsdorffii and their tumor-producing 4n, 3n, and 2n-hybrids were separated by thin-layer chromatography. The growth substances were eluted and subjected to an Avena curvature test. A

A novel protein elicitor (PaNie(234)) from Pythium aphanidermatum (Edson) Fitzp. was purified, microsequenced, and the corresponding cDNA was cloned. The deduced amino acid sequence contains a putative eukaryotic secretion signal with a proteinase cleavage site. The heterologously expressed elicitor

To test the possible interaction of polyamines in plant growth responses, transgenic tobacco plants containing the Avena sativa L. (oat) arginine decarboxylase (ADC) gene under the control of a tetracycline-inducible promoter were generated. Inducible overexpression of oat ADC in transgenic tobacco

BACKGROUND Carbon accumulation and remobilization are essential mechanisms in plants to ensure energy transfer between plant tissues with different functions or metabolic needs and to support new generations. Knowledge about the regulation of carbon allocation into oil (triacylglycerol) in plant

The physiological responses of transgenic tobacco (Nicotiana tabacum L.) plants that express high levels of an introduced oat (Avena sativa L.) phytochrome (phyA) gene to various light treatments are compared with those of wild-type (WT) plants. Seeds, etiolated seedlings, and light-grown plants

4-Hydroxyphenylpyruvate dioxgenase (HPPD) enzymes from rat and from several plants contained only about a single inhibitor-binding active site per dimer which matched the content of iron in the purified Arabidopsis thaliana and Avena sativa enzymes. The dimeric HPPDs were about 10 fold more

Previous reports on the incorporation of [(14)C]adenine into adenosine-3':5'-cyclic monophosphate (cyclic AMP) in oat (Avena sativa L.) and maize (Zea mays L.) coleoptile sections, chick-pea (Cicer arietinum L.) embryos and barley (Hordeum vulgare L.) aleurone layers were reexamined. Separation of
