tungsten/ダイズ

Tungsten (W) finds increasing application in military, aviation and household appliance industry, opening new paths into the environment. Since W shares certain chemical properties with the essential plant micronutrient molybdenum (Mo), it is proposed to inhibit enzymatic activity of molybdoenzymes

Increasing use of tungsten (W)-based products opened new pathways for W into environmental systems. Due to its chemical alikeness with molybdenum (Mo), W is expected to behave similarly to its "twin element", Mo; however, our knowledge of the behavior of W in the plant-soil environment remains

The effect of tungsten on the development of endogenous and nitrate-induced NADH- and FMNH(2)-linked nitrate reductase activities in primary leaves of 10-day-old soybean (Glycine max [L.] Merr.) seedlings was studied. The seedlings were grown with or without exogenous nitrate. High levels of

The effect of vanadium oxyanions on genome of soybean (Glycine max L., Merr.) in tungsten-resistant cell line was studied. The line is resistant to V(5+)-oxyanions. RAPD-amplicons with identical length are differentially synthesized from DNAs of tungsten-resistant cell line as well as of the initial

The mutagenic effect of an industrial enterprise (tungsten and molybdenum factory) was studied in three stages. At the first stage, the putative impact of the industrial sewage of the factory was studied using three plant test systems: Crepis capillaris L., Tradescantia sp. clone 02, and Glycine max

The Biolistics(®) particle delivery system for the transformation of soybean (Glycine max L. Merr.) was evaluated in two different regeneration systems. The first system was multiple shoot proliferation from shoot tips obtained from immature zygotic embryos of the cultivar Williams 82, and the

No phytochrome can be detected spectrophotometrically in soybean (Glycine max (L.) Merr. cv. Mandarin) cell suspensions grown in darkness. White light from a tungsten filament lamp and a band of far-red light have been found to induce the appearance of phytochrome in them. Red light failed to bring

The development of an efficient transformation system is a prerequisite for the molecular analysis of gene expression in plants. In crop plants, this development has been hindered by difficulties encountered both in whole plant regeneration from protoplasts and in the general insusceptibility of

The first successful attempt to generate genetically modified plants expressing a transgene was preformed via T-DNA-based gene transfer employing Agrobacterium tumefaciens-mediated genetic transformation. Limitations over infectivity and in vitro tissue culture led to the development
