Modification of storage proteins in the barley grain increases endosperm zinc and iron under both normal and elevated atmospheric <span>CO<sub>2</sub></span> Open
Increasing atmospheric CO 2 concentration is expected to enhance the grain yield of C 3 cereal plants, while at the same time reducing the concentrations of minerals and proteins. This will lead to a lower nutritional quality and increase …
