Water stress exists in most sugarcane cultivation areas, which are not supported by irrigation system and have low rain precipitation. Better understanding of physiological and biochemical mechanism, underlying plants response to water stress, have been achieved to develop drought-tolerant plants by biotechnology approach. To survive and grow normally, plants use a range of strategies to cope the water stress such as changes in gene expression and accumulation of organic compound called compatible solutes. Observation of drought stress response in sugarcane found the presence of a drought-inducible protein called SoDip22 and that the expression was induced by drought stress and ABA hormone treatments. However, the function of this drought-inducible protein has not been elucidated and only suggested that the protein may play an important role in maintenance of water molecule during water deficit state. Biochemical studies on the drought-tolerance mechanism have shown that nontoxic small compound of compatible solute accumulated during water deficit condition. Genetic engineering of glycine betaine (GB), acting as a compatible solute, has been applied for enhancement of water stress tolerance. In sugarcane, bacterial betA gene encodes for choline dehydrogenase (CDH) has successfully introduced and resulted in the transgenic drought-tolerance sugarcane. The CDH converts choline into betaine aldehyde, which is then converted to GB. The overexpression of betA gene increased GB contents that act as an osmoprotectant and help sugarcane acclimate in water deficit condition. This chapter reports the development of biotechnology for drought-tolerant sugarcane.

Sugarcane is the most important plant source for sugar and alcohol production and is cultivated in more than 80 countries in tropical and subtropical areas. However, environmental factors negatively influence its yield and jeopardize the prospect to meet the increasing demand for sugar, other sugarcane derived by products and bioethanol. The development of stress tolerant plants is fundamental for the maintenance and increase of crop yields. Biotechnology to Enhance Sugarcane Productivity and Stress Tolerance provides a comprehensive account of both theoretical and practical aspects of sugarcane production. It contains extensive coverage of genome mapping and molecular breeding in sugarcane and presents the status of the elucidation and improvement of plant genomes of economic interest. Through 14 chapters written by eminent scientists with global influence, this book examines various methods for sugarcane improvement through biotechnology. The book focuses on genetic and physical mapping, positioning, cloning, and monitoring of desirable genes using biotechnological approaches for high sugarcane productivity and the development of stress tolerance. Additional information includes the bioengineering of sugarcane, procedures to boost productivity, genetics and assessments for resistance to drought and salinity, genetics for high yields, and various topics of research on sugarcane genetics. It serves as a detailed reference source for cane growers, sugar and sugarcane technologists, students, and professors.

Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.
