DNA Nanobiotechnology and Plant Breeding

The world population has increased tremendously within last few decades and there is a great challenge of food security worldwide. The challenge of providing adequate food supply becomes more significant when we observe a reduction in crop yield annually. Plant pests, pathogens and various environmental factors contribute towards low crop productivity. Rapidly changing climatic conditions further add in epidemics of new pathogens. Classical breeding programs have significantly helped us in management of a sustainable food supply but with exponentially increasing population pressure together with high insurgence of pathogens/pests, we require multiple tasking to achieve better results. Modern techniques like plant tissue culture, transformation, RNAi, nanotechnology combined with classical techniques may rescue us from food shortage and help in achieving adequate supply of quality food in future.
