allelopathy refers to the chemical inhibition or stimulation of one species by another which could influence on the growth or germination of other plant and used in control of weed in agricultural practices. in this sense in order to study the possibly allelopathic effects of lemon balm, bitter apple and lemon verbena medicinal plants on control of wild mustard weed, a laboratory experiment was...

Selenium (Se) can be assimilated and volatilized via the sulfate assimilation pathway. Cystathionine-gamma-synthase (CGS) is thought to catalyze the synthesis of Se-cystathionine from Se-cysteine, the first step in the conversion of Se-cysteine to volatile dimethylselenide. Here the hypothesis was tested that CGS is a rate-limiting enzyme for Se volatilization. Cystathionine-gamma-synthase from...

Selenium (Se) can be assimilated and volatilized via the sulfate assimilation pathway. Cystathionine-c-synthase (CGS) is thought to catalyze the synthesis of Se-cystathionine from Se-cysteine, the first step in the conversion of Se-cysteine to volatile dimethylselenide. Here the hypothesis was tested that CGS is a rate-limiting enzyme for Se volatilization. Cystathionine-c-synthase from Arabido...

Background: Mustard is an oil seed crop and most oilseed crops are cross pollinated. A substantial increase in production requires adequate pollination. Rapeseed mustard both self-pollinated cross-pollinated plants. Brown sarson a pollinated whose reliant on honeybees wild insect pollinators. Methods: All parameters were carefully monitored during 2019-2021 growing year. blooming was visited by...

BACKGROUND Gene flow between crops and weedy relatives depends on the survivorship and reproduction of early-generation hybrids in a field environment. The primary aim of this study was to compare the fitness of transgenic crop x wild hybrids with their parental types and a non-transgenic crop type in the field under enhanced temperature and humidity. RESULTS Transgenic insect-resistant oilse...

A novel Li-impregnated TiO2 catalyst loaded on feldspar mineral (Li-TiO2/feldspar) was synthesized via a wet impregnation method and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) analysis. Using these techniques, it possible to confirm the catalyst’s structural organization with high crystallinity. This used in transesterifica...

Neurons of the developing brain are especially vulnerable to environmental agents that damage DNA (i.e., genotoxicants), but the mechanism is poorly understood. The focus of the present study is to demonstrate that DNA damage plays a key role in disrupting neurodevelopment. To examine this hypothesis, we compared the cytotoxic and DNA damaging properties of the methylating agents methylazoxymet...

The aim of the study was to develop a new method for mercury determination from plants grown on mercury-polluted soils as well evaluate mobility and bioavailability in soil its transfer different plant organs (root, stem, leaves) three plants, such mustard (Sinapis alba), thyme (Thymus serpyllum) wild thyme. A cold vapor atomic absorption spectrometry (CV-AAS) detection developed. developed val...
