Therefore, decreasing the cell ROS level is a key factor in the mitigation of Cd stress. Redox regulators also play an important role in the regulation of Cd stress. The presence of ROS activates signaling pathways such as MAPK and CDPK kinases, resulting in the phosphorylation of transcription factors such as WRKY. Reactive oxygen species (ROS) is the key signaling molecule that responds to Cd. Plant cells sense Cd with the help of transition metal transporters and plasma membrane reductases. Therefore, the mitigation of Cd stress and prevention of Cd accumulation in cereals is important. But Cd accumulation retards plant growth and crop productivity. Genetic engineering seems likely to provide resistance to diseases for which adequate and effective resistance is currently not available.Ībin Sebastian, Majeti Narasimha Vara Prasad, in Cadmium Tolerance in Plants, 2019 AbstractĬereals crops such as rice, wheat, and maize accumulate toxic levels of cadmium (Cd). Genetic transformation will provide opportunities for transferring resistance genes from species that cannot be hybridized with individual cereal species as well as possibilities for synthesizing new genes in the laboratory. Mapping information is being used for marker-assisted selection, aimed at developing resistance gene combinations to provide more durable and effective resistances. In the host species, resistance genes have been mapped and cloned.

Molecular biology is providing tools for more accurate diagnostics of pathogens at both species and subspecies levels, some pathogenicity factors have been cloned and their gene products identified. Emphasis on resistance is expected to increase as fungicide use and residues become less acceptable. Wrigley, in Encyclopedia of Food Grains (Second Edition), 2016 Future ProspectsĬereal crops will continue to be affected by diseases as no breeding program can develop cultivars with acceptable levels of resistance to all diseases under all conditions.
