“…With prolonged and severe deficiency, symptoms usually center around two of the body areas, the heart and the joints (Diplock 1992). It is reported that numerous reports associate Se deficiency with several reproductive and obstetric complications include preeclampsia, fetal growth restriction, male and female infertility, miscarriage, gestational diabetes, preterm labor and obstetric cholestasis (Sager 2006;Knez and Graham 2013).…”

“…Unlike animals and humans, plants can synthesize all organic molecules, such as vitamins and amino acids that they require, that is, they need only water, air and minerals (Knez and Graham 2013). It is reported that malnutrition globally is responsible for deaths [20 million mortalities annually (Kennedy et al 2003;WHO/FAO 2003), whereas more than five million childhood deaths occur from micronutrient malnutrition every year (Bouis and Welch 2010).…”

“…Furthermore, collaboration among agriculture, health and nutrition sectors is essential in the development programs that can reduce the number of people suffering from micronutrient deficiencies in a most effective Environ Chem Lett way (Knez and Graham 2013). It could be distinguished that agricultural programs have not been designed to promote human health, but are mainly focused on increasing yields, productivity and general food availability (Knez and Graham 2013). One well-known agricultural strategy is crop mineral biofortification, which is achieved by agronomic fertilization with metal salts.…”

Selenium in soils under climate change, implication for human health

Global climate changes can alter the suitable geographical range of different crops, leading to possible changes in cropping pattern and its extent in some regions. For example, temperature changes can interact very closely with changes in availability of water and soil nutrients, and crop growth cycle. The consequences of the biophysical impacts of climate changes will be influenced by the human responses to these impacts. There is a strong link between soils and human health, and these soils per se are controlled by climate changes. The human health is very close to both selenium (Se) element and climate changes. It is estimated that about 37-40 % of the total Se emissions to the atmosphere are due to the anthropogenic activities.Those anthropogenic activities, which are sources of Se, include coal and oil combustion, mining activities, the utilization of rock phosphates as a fertilizer and the application of sewage sludge to agricultural land. It was thought that selenium was a toxicant for a long time due to inadequate analytical data. In the recent past, Se has become very important in environmental biogeochemistry because of its influence on human health. Although Se is an essential nutrient for animals and humans, it is also toxic at high doses. Furthermore, the range between Se deficiency, lower than 40 lg day -1 , and toxicity, higher than 400 lg day -1 , is narrow. Selenium deficiency has been linked to several human diseases including multiple sclerosis, muscular dystrophy, heart disease, immune system, cancer and reproductive disorders. On the other hand, Se toxicity can lead to hair and nail loss and disruption of the nervous and digestive systems in animals and humans. Despite the obvious connections between Se element and human health under climate changes, there has not been a great amount of research done in this area. So, more and more studies should be carried out to enhance and protect human health. Therefore, this article reviews the biological and economic dimensions of the effects of Se element on human health under climate changes.

“…Zinc is one of the nutrients being targeted in biofortification programs. Zinc deficiency in soils is a critical problem for cereal production, limiting the grain yield of crops in many parts of the world (SADEGHZADEH, 2013) as well as diminishing grain nutritional quality and human health (KNEZ and GRAHAM, 2013). Zinc deficiency declines the productivity of about 30% of cultivated lands around the world (ALLOWAY, 2008).…”

Identification of MFLP fingerprint for higher seed zinc accumulation in barley DH population

2017

Selection through molecular markers for seed Zn accumulation might be an efficient complementary breeding tool in barley breeding. To develop a specific molecular markers, 150 DH lines derived from a cross between Clipper (low-Zn-accumulator) and Sahara-3771 (high-Zn-accumulator) were screened under field and glasshouse conditions. Microsatellite-anchored fragment length polymorphism (MFLP) fingerprint generated by SSR-anchor primer MF128 in combination with AFLP primer MseI-AGA (5?-GATGAGTCCTGAGTAAAGA-3?) was identified as a candidate marker for tagging seed Zn accumulation gene. The sequencing of the band showed a marker of 369 bp with the sequence of SSR anchor primer MF128 and MseI-AGA at the two ends as expected. The MFLP marker associated with higher seed Zn accumulation has potential to be converted to a simple, sequence-specific, PCR-based, low-cost marker amenable to large populations, making it potentially viable for marker-assisted selection in barley breeding. This marker might be useful in the improvement of barley productivity and nutritional quality in Zn-deficient environments.
