Cadmium (Cd) is a highly toxic heavy metal for both plants and animals. The presence of Cd in agricultural soils is of great concern regarding its entry into the food chain. Cadmium enters into the soil-plant environment mainly through anthropogenic activities. Compounds of Cd are more soluble than other heavy metals, so it is more available and readily taken up by plants and accumulates in dif...

Improvements in understanding how climate change may influence chemical and physical processes in soils, how this may affect nutrient availability, and how plants may respond to changed availability of nutrients will influence crop breeding programmes. The effects of increased atmospheric CO2 and warmer temperatures, both individually and combined, on soil microbial activity, including mycorrhi...

This study was performed to investigate the association between hair mineral levels and nutrient intakes, age, and BMI in female adults who visited a woman's clinic located in Seoul. Dietary intakes were assessed by food frequency questionnaire and mineral levels were measured in collected hairs, and the relationship between these was examined. The average daily nutrient intakes of subjects wer...

Reproductive efficiency is critical to the profitability of all dairy operations. Each additional day required for a cow to conceive, after 90 days of lactation, costs between $0.50 and $4.00 (US$) per day (22). Improving reproductive efficiency can be difficult as it is influenced by many factors including plane of nutrition, rate of weight gain, level of stress and level of milk production. I...

Kanamycin production by Streptomyces kanamyceticus ATCC 12853 requires magnesium sulfate and potassium phosphate at concentrations of 0.4 and 1.0 g per liter, respectively. The optimal concentrations of Fe and Zn for production of kanamycin are 0.25 and 0.575 mug/ml, respectively, whereas Mo at 0.04 mug/ml allows maximal cellular growth and antibiotic synthesis. Mn and Ca are without any effect...

Limitation in crop yield productivity significantly contributes to the pressing problem of food security and malnutrition worldwide. [...].

Low birth weight (LBW) remains a significant public health problem in many developing countries, and poor nutrition both before and during pregnancy is recognized as an important cause. Emerging evidence on the role of intergenerational effects in determining maternal preconceptual nutritional status indicates the need for continued investment in strategies that improve women's nutrition and he...

Considered to play an important role in plant mineral nutrition, arbuscular mycorrhizal (AM) symbiosis is a common relationship between the roots of a great majority of plant species and glomeromycotan fungi. Its effects on the plant host are highly context dependent, with the greatest benefits often observed in phosphorus (P)-limited environments. Mycorrhizal contribution to plant nitrogen (N)...

BACKGROUNDS AND AIMS Nitrogen nutrition of legumes, which relies both on atmospheric N2 and soil mineral N, remains a major limiting factor of growth. A decade ago, breeders tried to increase N uptake through hypernodulation. Despite their high nodule biomass, hypernodulating mutants were never shown to accumulate more nitrogen than wild types; they even generally displayed depressed shoot grow...
