Abstract
As cereal crops are the main source of micronutrients such as Zn, subsequently Zn-deficient food crops are responsible for causing hidden hunger and malnutrition in people living in developing countries. Moreover, crop plants such as wheat, rice, maize, and sorghum show reduced photosynthetic carbon metabolism due to Zn deficiency. Different approaches are in progress to improve the Zn insufficiency in cereal. Strategies for the improvement of the Zn contents of food crops like chemical fertilization, agronomic practices, and transgenic plants development appear to have potential; however, these engaged practices have increased the environmental pollution, high-cost, socioeconomic, and political issues. The use of plant growth-promoting rhizobacteria (PGPR) offers an attractive approach to substitute chemical fertilizer, pesticides, and supplements. In particular, in vivo trials of Zn-mobilizing PGPR result in cereal biofortification.
