Light stimulates the accumulation of cytoplasmic and plastid rRNA in the cotyledons of mustard (Sinapis alba L.) seedlings. This effect is mediated by phytochrome. Continuous far red irradiation and brief red light pulses (the effect of which is reversible by brief far red light pulses) increase the amount of 1.3 x 10(6) + 0.7 x 10(6) and 1.1 x 10(6) + 0.56 x 10(6) molecular weight rRNA species...

The flea beetle, Phyllotreta nemorum L. (Coleoptera: Chrysomelidae), is an intermediate specialist feeding on a small number of plants within the family Brassicaceae. The most commonly used host plant is Sinapis arvensis L., whereas the species is found more rarely on Cardaria draba (L.) Desv., Barbarea vulgaris R.Br., and cultivated radish ( Raphanus sativus L.). The interaction between flea b...

Myrosinase from white mustard seeds (Sinapis alba) has been purified starting from aqueous crude extract in a single step by affinity chromatography on Con A-Sepharose. The specific activity, recovery, and binding capacity in four separate trials using glucose, mannose, methyl a-D-glucoside, and methyl a-D-mannoside for elution were also determined. The enzyme isolated by our approach showed a ...

The influence of phytochrome (high irradiance reaction; operationally, continuous far red light) on the incorporation of [(3)H]uridine into the cytoplasmic 2.5 megadalton precursor rRNA in the cotyledons of mustard (Sinapis alba L.) seedlings has been investigated. After irradiating 36-hour-old etiolated seedlings with 12 hours of far red light, the rate of incorporation is stimulated about 2-f...

Field, greenhouse, and laboratory experiments were conducted to evaluate the impact of soil moisture and phosphorus on allelopathic potential of wheat residues, and to study the effect of wheat extract concentrations on the germination and growth of wild mustard (Sinapis arvrnsis L.). The field experimental design was split-plot with 4 replications. The main factor was three moisture levels inc...

Removing bottom sediment from water reservoirs and rivers can, on the one hand, be an effective method to restore lakes, other - used for plant production, ensuring recycling of nutrients. The aim this research was evaluate possibilities using various types its impact heavy metal content in soil plants. For purpose, a pot experiment carried out white mustard (Sinapis alba) as test plant. total ...
