Jatropha, Challenges for a New Energy Crop, 1st ed. 2019 Volume 3: A Sustainable Multipurpose Crop

Jatropha curcas, or physic nut, is a small tree that, in tropical climates, produces fruits with seeds containing ~38% oil. The physic nut has the potential to be highly productive and is amenable to subculture in vitro and to genetic modification. It also displays remarkable diversity and is relatively easy to cross hybridize within the genus. Thanks to these promising features, J. curcas is emerging as a promising oil crop and is gaining commercial interest among the biofuel research communities. However, as a crop, physic nut has been an economic flop since 2012, because the species was not fully domesticated and the average productivity was less than 2 t/ha, which is below the threshold of profitability.^7 t/ha could be reached and it is contributing to new markets in some countries. As such, it is important fro research to focus on the physiology and selective breeding of Jatropha .

This book provides a positive global update on Jatropha, a crop that has suffered despite its promising agronomic and economic potential. The editors have used their collective expertise in agronomy, botany, selective breeding, biotechnology, genomics and bioinformatics to seek out high-quality contributions that address the bottleneck features in order to improve the economic trajectory of physic nut breeding.

Mulpuri Sujatha graduated in Plant Sciences from the University of Hyderabad (UoH), India. She has a Ph.D. in Genetics from Osmania University (OU), Hyderabad, and has worked on intergeneric and interspecific affinities between Ricinus and Jatropha. Dr. Sujatha is a versatile researcher, adopting conventional and modern tools for the improvement of oilseed crops encompassing the areas of genetics, tissue culture and biotechnology. Her achievements include the development stable male sterile lines in safflower, sunflower and niger; optimization of tissue culture and genetic transformation protocols; development of transgenic events in castor for foliage feeders and sunflower for resistance to necrosis disease; use of molecular markers in diversity analysis and tagging of desirable traits in sunflower (downy mildew, fertility restoration) and Jatropha (non-toxicity). Dr. Sujatha has also carried out pioneering work on Jatropha with regard to tissue culture, genetic diversity analysis of native and world collections and interspecific hybridization, which have provided valuable leads for genetic enhancement of J. curcas.
