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 (Uo H), 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.
Nicolas Carels graduated in Agronomy in Belgium and completed a Ph D in Plant Pathology (FUSAGx, Gembloux) prior to working as a scientist on the elaboration of the first genetic map of sugarbeet at the end of the 1980’s (ICIseed-SES, Belgium). He then moved to Paris (IJM, CNRS, France) where he completed a second Ph D on the genome organization in plants. He continued his work on genomics in Italy (SZN, Naples) and Spain (INTA-CAB, Madrid, Torrejon de Ardoz) before moving to Brazil (Bahia, Ilhéus, UESC), where he contributed to the application of bioinformatics and genomics to the improvement of Cacao and Rubber Tree for resistance to fungal diseases. His initial investigations on Jatropha covered the measurement of the genome size by flow cytometry and the application of reverse genetics to detect QTLs for oil production with the purpose of breeding Jatropha for this trait. He is now a Federal Officer of Fiocruz (Rio de Janeiro, Brazil) and is interested in the exploration of genomics, system modeling, bioinformatics, computational biology, and natural products for the benefit human health, with a particular focus on therapeutics for cancer.
Bir Bahadur, formerly Professor, Chairman and Head of the Department, and Dean of the Faculty of Science at Kakatiya University, Warangal, India, he has also taught at Osmania University, Hyderabad, India. He obtained his Ph.D. in Plant Genetics from Osmania University and was closely associated with Prof. J.B.S. Haldane, F.R.S, a renowned British geneticist. He made significant contributions in several areas of plant biology, especially heteromorphic incompatibility; genetics; mutagenesis; plant tissue culture morphogenesis; biotechnology; plant asymmetry and handedness; ethnobotany; application of SEM pollen and seeds in relation to systematics;medicinal plants; and Jatropha and Castor. He has mentored thousands of graduates and postgraduate students and taught genetics, biotechnology, plant molecular biology, plant reproduction, and related subjects for over 45 years and has accumulated 50 years of research experience in these areas. He has been the recipient of nu, erous awards, fellowships and honors, including the Prof. Vishwambar Puri Gold Medal, Bharath Jyoti Award, Royal Society Bursary & Honorary Fellow of Birmingham University (UK).
