Book Description
Bambara groundnut is a drought-tolerant African legume. In order to estimate biodiversity, a DArT genotyping array was developed from which 296 unique markers were obtained. It was shown that the cultivated form was characterised by a generally narrow genetic basis and further genetic bottlenecks occurred with the dispersal of germplasm. Through 454 pyrosequencing of eight cDNA populations from contrasting genotypes and different treatments and a cDNA microarray constructed from selected transcripts, a complex network of gene regulation in leaves under water-deficit was described. In addition, two potentially novel candidate genes for drought-tolerance were identified. The approaches presented in this thesis could serve as an example to produce significant population genetic and transcriptomic data for other under-researched crops in a time- and cost-efficient way.

Book Description
This book describes the concepts, strategies and techniques for pulse-crop improvement in the era of climate change, highlighting the latest advances in plant molecular mapping and genome sequencing. Genetic mapping of genes and QTLs has broadened the scope of marker-assisted breeding and map-based cloning in almost all major pulse crops. Genetic transformation, particularly using alien genes conferring resistance to herbicide, insects and diseases has facilitated the development of a huge number of genetically modified varieties of the major pulse crops. Since the genome sequencing of rice in 2002, genomes of over 7 pulse crops have been sequenced. This has resulted in the possibility of deciphering the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing has opened up a new vista for exploring wild crop relatives for identification of useful donor genes.

Book Description
Climate resilience, or the capacity of socio-ecological systems to adapt and upkeep their functions when facing physical-chemical stress, is a key feature of ecosystems and communities. As the risks and impacts of climate change become more intense and more visible, there is a need to foster a broader understanding of both the impacts of these disruptions to food, water, and energy supplies and to increase resilience at the national and local level. The Handbook of Climate Change Resilience comprises a diverse body of knowledge, united in the objective of building climate resilience in both the industralised and the developing world. This unique publication will assist scientists, decision-makers and community members to take action to make countries, regions and cities more resilient.

Book Description
The Bambara groundnut (BGN) or Vigna subterranea is an extremely hardy grain legume. As it produces reasonable yields even under conditions of drought and low soil fertility, it is also a climate-smart crop. Previously underutilized, BGN is the subject of growing interest among researchers and consumers for its balanced nutritional profile. Indigenous consumers of BGN report medicinal benefits from the plant; however, such knowledge is at risk of being lost with the urbanization and changing lifestyles of younger generations. To date, there is no comprehensive resource on the Bambara groundnut, despite market demand for plant proteins around the globe. Authored by scientists who have researched and developed patents using BGN, Bambara Groundnut: Utilization and Future Prospects aims to fill this gap. The text provides in-depth coverage on breeding, food and feed utilization, medicinal benefits and future research prospects. Drawing on both indigenous knowledge and cutting-edge research, Bambara Groundnut is the first book to fully explore the potential of this remarkable crop.

Book Description
This book highlights modern strategies and methods to improve oilseed crops in the era of climate change, presenting the latest advances in plant molecular breeding and genomics-driven breeding. Spectacular achievements in the fields of molecular breeding, transgenics and genomics in the last three decades have facilitated revolutionary changes in oilseed- crop-improvement strategies and techniques. Since the genome sequencing of rice, as the first crop plant, in 2002, the genomes of about one dozen oilseed crops have been sequenced and more are to follow. This has made it possible to decipher the exact nucleotide sequence and chromosomal positions of agroeconomic genes. Most importantly, comparative genomics and genotyping-by-sequencing have opened up new vistas for exploring available biodiversity, particularly of wild crop relatives, for identifying useful donor genes.

Book Description
The book covers the latest development in the biosciences field covering key topics in crop improvement including ‘omic approaches to improving sustainable crop production, advancement in marker technology, strategies in genetic manipulation, crop quality and sustainability and plant microbe interaction detailing on proven technologies to address critical issue for agricultural sustainability which are beneficial for researchers and students. The book also includes aspects of preserving crops after harvest as this is a key factor in promoting sustainable crop quality in terms of addressing waste, choosing the appropriate packaging and moving crops through the food and industrial supply chain. An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.

Book Description
The oil palm is a remarkable crop, producing around 40% of the world’s vegetable oil from around 6% of the land devoted to oil crops. Conventional breeding has clearly been the major focus of genetic improvement in this crop. A mix of improved agronomy and management, coupled with breeding selection have quadrupled the oil yield of the crop since breeding began in earnest in the 1920s. However, as for all perennial crops with long breeding cycles, oil palm faces immense challenges in the coming years with increased pressure from population growth, climate change and the need to develop environmentally sustainable oil palm plantations. In Oil Palm: Breeding, Genetics and Genomics, world leading organizations and individuals who have been at the forefront of developments in this crop, provide their insights and experiences of oil palm research, while examining the different challenges that face the future of the oil palm. The editors have all been involved in research and breeding of oil palm for many years and use their knowledge of the crop and their disciplinary expertise to provide context and to introduce the different research topics covered.
