“…On calcareous soils with low available Zn < 0.5 mg kg -1 , the current wheat grain Zn concentration is 223 around 20 mg kg -1 , as reported in China, Kazakhstan, Mexico, Turkey, and Zambia, etc. (Zou et al,224 2012; Liu et al, 2014). In the present study on calcareous soils with available Zn of 0.4 mg kg -1 , the 225 wheat cultivar Zhengmai 7698 had the highest Zn.a of 31.3 mg kg -1 and the yield of 6.6 t ha -1 in 226 2014, which was still lower than the Zn.t.…”

15The solution to address global human Zn deficiency is Zn biofortification of staple food crops, aimed 16 at high grain Zn concentration as well as high yield. However, the desired high grain Zn 17 concentration above 40 mg kg -1 is rarely observed for high-yield wheat on worldwide calcareous 18 soils, due to inadequate Zn uptake or Zn distribution to grain. The present study aims to investigate 19 how much Zn uptake or distribution is adequate to achieve the Zn.t of high-yield wheat on calcareous 20 soils with low available Zn (~ 0.5 mg kg -1 ). Of the 123 cultivars tested in a three-year field 21 experiment, 19 high-yield cultivars were identified with similar yields around 7.0 t ha -1 and various 22grain Zn concentrations from 9.3 to 26.7 mg kg -1 . The adequate Zn distribution to grain was defined 23 from the view of Zn biofortification, as the situation where the Zn distribution to grain (Zn harvest 24 index) increased to the observed maximum of ~ 91.0% and the Zn concentration of vegetative parts 25 (straw Zn concentration) decreased to the observed minimum of ~ 1.5 mg kg -1 (Zn.m). Under the 26 assumed condition of adequate Zn distribution to grain (~ 91.0%), all the extra Zn above Zn.m was 27 remobilized from straw to grain and the grain Zn concentration would be increased to its highest 28 attainable level, which was 14.5 ~ 31.3 mg kg -1 for the 19 high-yield cultivars but still lower than 40 29 mg kg -1 . Thus, even with the adequate Zn distribution to grain, the current Zn uptake is still not 30 adequate and needs to be increased to 308 g ha -1 or higher to achieve Zn.t for high-yield wheat (7.0 t 31 ha -1 ) on low-Zn calcareous soils. Besides, the established method here can also provide the priority 32 measures and quantitative guidelines to achieve Zn biofortification in other wheat production 33regions. 34

“…Grain Fe and Zn concentration of wheat is varied in different genotypes (Shi et al 2009;Zhang et al 2007;Oury et al 2006) and environmental factors, including fertilizer application (Liu et al 2014;Syltie et al 2005;Kutman et al 2010), drought (Amiri et al 2015) and CO 2 enrichment (Fernando et al 2014). In the present study, transgenic wheat and non-transformed wheat were in the general genetic background and grew in the same environment.…”

Iron deficiency is the most common nutritional disorder, affecting over 30% of the world's human population. The primary method used to alleviate this problem is nutrient biofortification of crops so as to improve the iron content and its availability in food sources. The over-expression of ferritin is an effective method to increase iron concentration in transgenic crops. For the research reported herein, sickle alfalfa (Medicago falcata L.) ferritin was transformed into wheat driven by the seed-storage protein glutelin GluB-1 gene promoter. The integration of ferritin into the wheat was assessed by PCR, RT-PCR and Western blotting. The concentration of certain minerals in the transgenic wheat grain was determined by inductively coupled plasma-atomic emission spectrometry, the results showed that grain Fe and Zn concentration of transgenic wheat increased by 73% and 44% compared to nontransformed wheat, respectively. However, grain Cu and Cd concentration of transgenic wheat grain decreased significantly in comparison with non-transformed wheat. The results suggest that the over-expression of sickle alfalfa ferritin, controlled by the seed-storage protein glutelin GluB-1 gene promoter, increases the grain Fe and Zn concentration, but also affects the homeostasis of other minerals in transgenic wheat grain.

“…Then, 50 mL of acetonitrile, 1 g of magnesium sulfate and 5 g of sodium chloride were added. This mixture was shaken for 1 h and then centrifuged at 4.0 × 10 rev min −1 for 5 min. A 20 mL aliquot of the supernatant was transferred to a 100 mL flat‐bottomed flask and evaporated until nearly dry using a rotary evaporator.…”

“…Wheat ( Triticum aestivum L.) is one of the world's most important cereal crops and is grown in 30 provinces in China, with a total cultivated area of 24.3 million ha . Wheat grain yield directly determines not only the income available to farmers but also the quality of wheat‐based food . Therefore, the concept of increasing grain yield has attracted much attention, and various measures have been undertaken to increase wheat production, including breeding new wheat varieties and improving crop nutrition and integrated pest management .…”
