TLDR
The results suggest that the enhanced capacity of genotypes for Zn uptake and translocation from roots to shoot meristems under deficient Zn supply might be the most important factor contributing to Zn efficiency in wheat genotypes.Abstract:
Six bread wheat (Triticum aestivum cvs. Kirac-66, Gerek-79, Aroona, ES 91-12, ES-14 and Kirkpinar) and four durum wheat (Triticum durum cvs. BDMM-19, Kunduru-1149, Kiziltan-91 and Durati) genotypes were grown under controlled environmental conditions in nutrient solution for 20 days to study the effect of varied supply of Zn (0 to 1 µM) on Zn deficiency symptoms in shoots, root and shoot dry matter production, and distribution of Zn in roots and shoots.read more

Tansley Review No. 111: Possible roles of zinc in protecting plant cells from damage by reactive oxygen species.
TL;DR: Zinc plays critical roles in the defence system of cells against ROS, and thus represents an excellent protective agent against the oxidation of several vital cell components such as membrane lipids and proteins, chlorophyll, SH-containing enzymes and DNA.

Zinc deficiency as a practical problem in plant and human nutrition in Turkey: A NATO-science for stability project
TL;DR: Measurement of Zn-containing superoxide dismutase activity in leaves revealed that an efficient utilization of ZN at the tissue or cellular level is an additional major factor involved in Zn efficiency of cereals.

Zinc deficiency as a critical problem in wheat production in Central anatolia
TL;DR: It is demonstrated that Zn deficiency is a critical nutritional problem in Central Anatolia substantially limiting wheat production, durum wheats possess higher sensitivity to Zn deficient conditions than bread wheats, and wheat plants grown in calcareous soils containing less than 0.2 mg kg-1 DTPA-extractable Zn significantly respond to soil Zn applications.
