    Within grains there are various anti-­nutrients that can prevent micronutrients from being absorbed by the body (Hambidge 2010). Phytate (inositol hexakisphosphate) is one such anti-­‐nutrient and is known to bind
    trace elements such as Zn2+, Fe2+, Mn2+ and Cu2+, thereby reducing their availability for absorption in the small intestine. Phytate is one of the main P stores in the grain with reports that phytate P constitutes up to 90% of the total grain P (Murgia et al. 2012). Here we investigate the affect of the overexpression of HvSUT1 in wheat on the levels of P and phytate in the grain to show that manipulation of the solute flux into the seed is likely to have an impact on Fe and Zn absorption in humans.

    ConferenceXVII International Plant Nutrition Colloquium
    Abbreviated titleIPNC'13
    OtherThe main theme of the 17th International Plant Nutrition Colloquium (IPNC) is "Plant nutrition for nutrient and food security". Ensuring food and nutrient security still represents a big global challenge. An adequate mineral nutrition offers excellent options and solutions to contribute to both food and nutrient security. There are several valuable examples in the past showing great contributions of plant nutrition research to food and nutrient security and thus well-being of human populations.
    It is hoped that the colloquium will be an excellent avenue for discussion, exchange and transfer of knowledge, as well as for creating new and fostering existing collaborations in the fields of plant mineral nutrition, plant molecular biology, plant genetics, agronomy, horticulture, ecology, environmental sciences and fertilizer use and production. We invite you to present the recent results of your research related to the different aspects of plant mineral nutrition.
