Detoxification of cassava leaves by simple traditional methods.

Numai utilizatorii înregistrați pot traduce articole

Cassava leaves, which usually contain large quantities of cyanogenic glycosides, were processed into a Zairian traditional vegetable sauce "Mpondu" by simple methods which included blanching (10 min), mashing and then boiling for 20-80 min. These methods enhanced the detoxification of the leaves,

Detoxification of Cassava Leaves by Thermal, Sodium Bicarbonate, Enzymatic, and Ultrasonic Treatments.

Numai utilizatorii înregistrați pot traduce articole

Cassava leaves are a valuable source of protein but the cyanogenic potential limits their use as food and feed. Four different treatments were investigated to detoxify cassava leaves. Thermal (55 °C for 6 hr), sodium bicarbonate (0.4% NaHCO₃ , 55 °C for 6 hr), enzymatic (0.32% Multifect®

Copper toxicity in leaves of Elodea canadensis Michx.

Numai utilizatorii înregistrați pot traduce articole

Elodea canadensis (Canadian waterweed) has an ability to accumulate and bioconcentrate heavy metals. In this work, selected cellular responses for Cu treatment were studied in leaves of E. canadensis. Short term experiments, i.e. 1 week exposure to 0.5, 1, 5, and 10 microM of Cu indicated that

Chlorophyll breakdown and chlorophyll catabolites in leaves and fruit.

Numai utilizatorii înregistrați pot traduce articole

Chlorophyll metabolism probably is the most visible manifestation of life. Total annual turnover of chlorophyll has been estimated to involve more than 1000 million tons. Surprisingly, chlorophyll catabolism has remained an enigma until less than twenty years ago, when a colorless chlorophyll

Internal Detoxification Mechanism of Al in Hydrangea (Identification of Al Form in the Leaves).

Numai utilizatorii înregistrați pot traduce articole

An internal detoxification mechanism for Al was investigated in an Al-accumulating plant, hydrangea (Hydrangea macrophylla), focusing on Al forms present in the cells. The leaves of hydrangea contained as much as 15.7 mmol Al kg-1 fresh weight, and more than two-thirds of the Al was found in the

Detoxification of aflatoxin B1 by an aqueous extract from leaves of Adhatoda vasica Nees.

Numai utilizatorii înregistrați pot traduce articole

The effectiveness of aqueous extracts of various medicinal plants in detoxification of aflatoxin B1 (AFB1) was tested in vitro by thin-layer chromatography and enzyme-linked immunosorbent assay (ELISA). Among the different plant extracts, the leaf extract of Vasaka (Adhatoda vasica Nees) showed the

Diurnal variation of apoplastic ascorbate in winter wheat leaves in relation to ozone detoxification.

Numai utilizatorii înregistrați pot traduce articole

Besides stomatal closure, biological detoxification is an important protection mechanism for plants against ozone (O3). This study investigated the diurnal changes of ascorbate (a major detoxification agent) in the apoplast and leaf tissues of winter wheat grown under ambient air field conditions.

Proteome analysis of peroxisomes from dark-treated senescent Arabidopsis leaves.

Numai utilizatorii înregistrați pot traduce articole

Peroxisomes compartmentalize a dynamic suite of biochemical reactions and play a central role in plant metabolism, such as the degradation of hydrogen peroxide, metabolism of fatty acids, photorespiration, and the biosynthesis of plant hormones. Plant peroxisomes have been traditionally classified

Effects of salinity levels on proteome of Suaeda aegyptiaca leaves.

Numai utilizatorii înregistrați pot traduce articole

Saline soils are the major problem of cultivated lands of Iran. Suaeda aegyptiaca is a salt-tolerant plant (halophytes) that grow naturally in salt-affected areas of Iran. We have employed proteomics to identify the mechanisms of salt responsiveness in leaves of S. aegyptiaca grown under different

Proteomic response of oat leaves to long-term salinity stress.

Numai utilizatorii înregistrați pot traduce articole

Salinity adversely affects plant growth and production. Oat is a moderately salt-tolerant crop and can contribute to improving saline soil. The physiological and molecular responses of the oat plant to long-term salinity were studied. After a 16-day salt treatment (150 mmol L-1NaCl in Hoagland's

UV radiation-responsive proteins in rice leaves: a proteomic analysis.

Numai utilizatorii înregistrați pot traduce articole

Depletion of stratospheric ozone has led to increased UV radiation reaching the surface of the Earth. This may damage plants. Using physiological, proteomic and quantitative real-time PCR (qPCR) methods, we systematically studied the response of 16-day-old rice seedlings to UV [0.67 W m(-2)

Identification of early senescence-associated genes in rice flag leaves.

Numai utilizatorii înregistrați pot traduce articole

Leaf senescence is one of the key stages of plant leaf development. It is a highly complex but ordered process involving expression of large scale senescence associated genes, and its molecular mechanisms still remain unclear. By using suppression subtractive hybridization, 815 ESTs that are

The different responses of glutathione-dependent detoxification pathway to fungicide chlorothalonil and carbendazim in tomato leaves.

Numai utilizatorii înregistrați pot traduce articole

Chlorothalonil (CHT) and carbendazim (CAR) are two widely used fungicides in agriculture. Despite their agronomic importance in pest control, little is known about their detoxification in the plant. In this study, we investigated the effects of these fungicides on glutathione (GSH) content,

Processes contributing to photoprotection of grapevine leaves illuminated at low temperature.

Numai utilizatorii înregistrați pot traduce articole

Photoinactivation of photosystem II (PSII) and energy dissipation at low leaf temperatures were investigated in leaves of glasshouse-grown grapevine (Vitis vinifera L. cv. Riesling). At low temperatures (< 15 degrees C), photosynthetic rates of CO(2) assimilation were reduced. However, despite a

Compartmentation of aluminium in leaves of an Al-accumulator, Fagopyrum esculentum Moench.

Numai utilizatorii înregistrați pot traduce articole

Buckwheat (Fagopyrum esculentum Moench.) is an Al-accumulating plant, but the internal mechanism(s) of detoxification of Al is not fully understood. We investigated the subcellular localization of Al in the leaves of this plant (cv. Jianxi) by directly isolating protoplasts and vacuoles. Pure
