Studies the impact and management of pollution on plants, resulting in plant abiotic stress physiology, reduces growth due to alterations in biochemical and physiological processes. It details harm to plants caused primarily by heavy metal contamination in soils, using pesticides, and by air pollution.

Presents the use of mutagenesis and biotechnology to explore the variability of mutant genes for crop improvement. It deals with in-vitro mutagenesis to exploit the somaclonal variations induced in cell culture. The chapters highlight the importance of in-vitro mutagenesis in inducing salt resistance and draught resistance.

Covers the genetic engineering techniques used to mutant genes and incorporate them in plant species of cereals, pulses, vegetables, and fruits. Addresses in-vitro mutagenesis and the principles of genetic engineering in which mechanism and action of transfer of desired genes from plants to animals to microorganism and vice versa.

Deals with mutagenesis, cytotoxicity, and crop improvement, discussing the processes, mutagenic effectiveness, and efficiency and mechanisms of mutagenesis. It emphasizes on improvement of agronomic characteristics by manipulating the genotype of plant species, resulting in increase in productivity.
