We describe a system for gene expression in plants based on the regulation mechanism of the yeast metallothionein (MT) gene. The system consists of two elements: (i) the yeast ace1 (activating copper-MT expression) gene encoding a transcription factor under control of the cauliflower mosaic virus (CaMV) 35S RNA promoter, and (ii) a gene of interest under control of a chimeric promoter consistin...

Iron and copper, the essential trace elements accomplish their numerous relevant metabolic functions appropriately in the body. Hepcidin, ferroportin-1 and transferrin are associated with iron metabolism and their expression can be affected under different physiological or pathological conditions. The aim of the current study was to investigate the changes in hepatic gene expression of these ir...

A total of 225 pigs (PIC 327 × 1050, initially 25.5 lb) were used in a 21-d trial to evaluate the effects of copper source and level on nursery pig growth performance. Pens of pigs were balanced by initial BW and randomly allotted to 1 of 5 dietary treatments with 9 replications per treatment. The 5 corn and soybean meal-based diets were arranged in a 2 × 2 + 1 factorial with main effects of co...

Moriculture is a significant factor for better production of silk in the field sericulture. The present study deals with influence micronutrients on increased growth and yield mulberry plants [MR2 (Mildew Resistant Variety 2)]. Field experiments comprising twelve treatments including controlsupplemented desired quantity single or combination were analysed to morphometric characteristic paramete...

This study aimed to determine the role of Saccharomyces cerevisiae in alleviating copper sulfate toxicity carp fish and by evaluating Acetylcholinesterase (AChE) activity histopathological alteration gills brain with determined severity lesions semi-quantities analysis. Sixty were divided into four groups first was a control group second exposed CuSO4 0.53 mg/L, third treated yeast 5 g/ kg rati...

Balanced use of micronutrients in soils is essential for optimized nutrient efficiency, environmental conservation and long-term sustainability agro-ecological systems. As a result, maintaining correct micronutrient levels the soil not only to meet plant needs maintain agricultural productivity but also avoid build-up. The present study aimed investigate effect application on yield sucrose cont...

Biosynthesis methods employing microorganisms have emerged as an eco-friendly, clean, and viable alternative to chemical physical processes. The present study reports the synthesis of copper oxide nanoparticles (CuONPs) using cell-free culture supernatant marine Streptomyces sp. MHM38. For optimized production CuONPs, influence some parameters, such concentration sulfate (CuSO4), reaction time,...
