Abstract: In order to provide guidance for wheat grain zinc (Zn) bio-fortification strategies and reasonable managements of nitrogen (N) fertilizers, the effects of nitrogen supply on zinc absorption, translocation and accumulation in wheat (Triticum aestivum L.) grains were summarized in this review. Based on the summary, the authors pointed out that certain topics should be further studied, including whether N supply could stimulate root Zn uptake by producing more zinc-regulated/iron-regulated transporter-like proteins (ZIPs), such as the iron-regulated transporter-like protein (IRT-like); whether more nitrogenous compounds (e.g. nicotianamine (NA)), organic acids (e.g. citrate), heavy metal ATPase (HMA) family proteins and yellow stripe-like (YSL) transporters could enhance Zn transfer from roots to above-ground parts, and whether more NA and YSL transporters could increase Zn remobilization from vegetative tissues to wheat grains. The authors suggested that researches related to different chemical forms of N (e.g. NH4-N and NO3-N) and foliar application should be the focus in the future, and the 15N and 67/68Zn stable isotopes labeling should be applied to further quantify the effect of N supply.
