Biotechnology has the potential to revolutionize the crop and plant sciences with the ability to increase food production and enhance plant responses to environmental stressors. As these technologies become more widespread there has been an increased focus on containing modified plants to specific areas. Plant Gene Containment brings together key concepts in gene flow and provides information on strategies being developed to curb the unwanted spread of modified traits.

Plant Gene Containment provides broad–ranging coverage of the topic, ranging from basic research findings to industrial application. The chapters are divided into two sections. The first section reviews concepts in gene containment, including environmental and commercial perspectives.

The second section reviews specific strategies currently used and in development, such as gene switch technology, plant sterility, gene–deletor technology, and seed–based technologies among others. 

Bringing together the valuable perspectives of a global and diverse group of experts, Plant Gene Containment will be an invaluable resource for crop and plant scientists, biotechnologists, and industry personnel.
