Secondary Metabolite Contents and Antioxidant Enzyme Activities of Cichorium intybus Hairy Roots in Response to Zinc
Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...

متن کاملGrazing cow and calf responses to zinc supplementation.
This experiment evaluated weight gain responses to supplemental Zn by cows and calves grazing forage containing less than 20 ppm Zn. One hundred cow-calf pairs in each of 2 years and 120 paird in a third year were pastured together over a 63- to 77-day preliminary period during which cows were exposed to bulls. Each experimental period began in mid-June after bulls were removed and continued fo...
متن کاملTranscriptomic profiling of Arabidopsis gene expression in response to varying micronutrient zinc supply.
Deficiency of the micronutrient zinc is a widespread condition in agricultural soils, causing a negative impact on crop quality and yield. Nevertheless, there is an insufficient knowledge on the regulatory and molecular mechanisms underlying the plant response to inadequate zinc nutrition [1]. This information should contribute to the development of plant-based solutions with improved nutrient-...
متن کاملZinc availability and digestive zinc solubility in piglets and broilers fed diets varying in their phytate contents, phytase activity and supplemented zinc source.
The study was conducted to evaluate the effects of dietary zinc addition (0 or 15 mg/kg of Zn as inorganic or organic zinc) to three maize-soybean meal basal diets varying in their native Zn, phytic P contents and phytase activity (expressed in kg of feed: P- with 25 mg Zn and 1.3 g phytic P, P+ with 38 mg Zn and 2.3 g phytic P or P+/ENZ being P+ including 500 units (FTU) of microbial phytase p...
