In laboratory conditions, the analysis of total toxicity some technogenically disturbed soils Belgorod region was carried out using bioassays: Daphnia magna Straus , green algae Scenedesmus quadricauda (Tiger) and Lepidium sativum L. As a result experiments, degree tested established. The conducted studies confirm high information content when three bioassays for soil toxicity.

With the rising trend toward use of natural substances in medicines, utilization cress seed mucilage (Lepidium sativum L.) has gained significant importance.Since Vedic period, subcontinent employed garden sativum) for medical reasons. There are several ecological and industrial uses that summarized this paper. The emerging evidence revealed Unani school medicine, seeds leaves plant might be us...

In some species, a crucial role has been demonstrated for the seed endosperm during germination. The endosperm has been shown to integrate environmental cues with hormonal networks that underpin dormancy and seed germination, a process that involves the action of cell wall remodeling enzymes (CWREs). Here, we examine the cell wall architectures of the endosperms of two related Brassicaceae, Ara...

Cladospirone bisepoxide (1), a novel metabolite, was isolated from cultures of a fungus which was characterized as a coelomycete by the formation of pycnidia. By optimization of media and fermentation conditions, a titer of up to 1.5 g/liter on shake level and 1.16 g/liter on bioreactor scale could be achieved. The isolation of the compound was performed by solvent extraction of the culture bro...

A new isoflavonoid, 5,6-dimethoxy-2',3'-methylenedioxy-7-C-β-d-gluco-pyranosyl isoflavone was isolated from the seeds of Lepidium sativum L. along with two known isoflavonoids, 7-hydroxy-4',5,6-trimethoxyisoflavone and 7-hydroxy-5,6-dimethoxy-2',3'-methylenedioxyisoflavone. The structures of all compounds were elucidated with NMR spectrometry. Compounds 1, 2 and the new isoflavonoid 3 were eval...

Twelve essential oils from Mediterranean aromatic plants were tested for their phytotoxic activity, at different doses, against the germination and the initial radicle growth of seeds of Raphanus sativus, Lactuca sativa and Lepidium sativum. The essential oils were obtained from Hyssopus officinalis, Lavandula angustifolia, Majorana hortensis, Melissa officinalis, Ocimum basilicum, Origanum vul...

A cDNA clone for NADPH : protochlorophyllide oxi­ doreductase from barley was subcloned for production of antisense-mRNA. This enabled heterologous hybridi­ zation with RNA from cress seedlings (Lepidium sativum L.). The mRNA level for N A DPH : protochlorophyllide oxidoreductase did not decrease in cress seedlings during irradiation with continuous far-red or white light up to 12 h. The amount...
