These are the driving forces that led governments worldwide to the implementation of renewable energies. Among, the renewable energies that started to contribute to the energy grid, biofuels are considered as an obligate step. Here, an attempt has been made to overview the particular case of Jatropha curcas L. and show how the international scientific community has concertedly contributed to draw it from anonymity in just few years and worked to implement it as an alternative biodiesel option to feed the energy grid.

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.

The fruits contained seed that are ~40% oil rich. This oil is excellent for biodiesel. The bush is a now new coming crop because it may cope with harsh environmental conditions such as semi-aridity and poor land. It is considered as one alternative for climate mitigation that does not compete with arable land normally dedicated to food crop and can be used to regain degraded land or fight desertification. This bush has been considered seriously by the international community only recently (2006-2008), but worldwide scientists did an outstanding job to drawn Jatropha out of its semi-wild status and bring it on the industrial scene. Problems remains, but we have now a comprehensive picture of this crop and almost every technological challenged were addressed. From now, the job will have to concentrate on breeding in order to domesticate this species. Therefore, it is the right time to sum up worldwide contributions in a comprehensive book with a breeding looking to improve the chance of this plant to stabilize as a crop and to fulfil with the expectations that humans invested in it. A book with this perspective will help international community to give a step on. The book will be a broad and comprehensive look on Jatropha until the details since the book is being contributed by international experts worldwide that have already published works in the international press of Science. Illustrations, tables geographic maps, GPS location, etc are added by each contributors according to the feeling they have concerning what they think their contribution should be.

Illustrations, tables geographic maps, GPS location, etc are added by each contributors according to the feeling they have concerning what they think their contribution should be. This book will benefit the scientific community immensely. Being aware of any challenges related to Jatropha, i.e. (i) its economy in Asia (India, China) and South America (Brazil), (ii) basics of biofuel technology, (iii) physiology, (iv) farming, (v) byproducts, (vi) biotechnology, (vii) genetic resource (germplasm) and their benefit for the crop by genetic transfer, (viii) genetic map, (ix) comparative genetics, (x) genomics. Breeders and technologist will have access to a complete digested view on Jatropha to decide where and how they should move on with their investigations.

The main challenge in these processes is that they must be coherent with the emergence of self-reproducing systems from simple in- and organic chemistry as well as being compatible with natural selection. As in other sciences like physics, the detailed understanding of the most fundamental processes led to key breakthrough technological achievements. For instance, the artificially induced evolution of catalytic systems under directed selective constraints is an important issue for the processing industry. It is amazing to realize how fast complex biological systems arose and evolved in the early time of Earth. Here, it has been our aim to try to give a constructive view of how chemical information contributed to biological self-organization.
