Book Description
Sorghum (Sorghum bicolor L., Moench) is the fifth most important cereal crop in the world and represents an important source of food, feed and energy in several countries. Recently, there has been an increasing interest in sorghum cultivation worldwide, since it is relatively more drought- and heat-tolerant than other cereal crops, and it is better suited for the predicted consequences of global warming. In Africa and Asia, sorghum is primarily used as food for more than 500 million people, while in the Americas and Australia, it is used mainly as a maize-substitute in livestock feed. In the United States, sorghum is also being used in the production of ethanol. In view of its diverse utility, sorghum offers a large number of target traits that could be modified to meet the required applications. In this work, we have used different genetic engineering approaches to address two important issues in sorghum: seed quality and nitrogen use efficiency. First, we examined the temporal and spatial activity of a rice glutelin gene (GluA-2) promoter, in transgenic sorghum. Results from quantitative and histochemical GUS assays, as well as from transcript analyses, showed that this promoter is highly active during the middle stages of sorghum seed development and that it controls transgene expression specifically in the seed endosperm. This means that the GluA-2 promoter can serve as a useful tool in introducing novel traits into sorghum seed in order to improve the quality of this important cereal. Furthermore, we investigated the effects of cytosolic glutamine synthetase (GS1) and alanine aminotransferase (AlaAT) gene overexpression on nitrogen metabolism and plant growth in sorghum. T_(2) generation plants transformed with a sorghum GS1 gene (Gln1) driven by the maize ubiquitin promoter exhibited enhanced grain yield and biomass accumulation under optimal nitrogen levels.

Book Description
This edited book is focused on Sustainable Development Goal 2, which aims to achieve 'Zero Hunger.' It provides deep insights into the global sorghum status, limitations to its production, advancements in agronomic practices, and the application of high-throughput phenotyping technologies. Sorghum plays a vital role in global food security, agricultural sustainability, and rural livelihoods, making it an important crop for both developing and developed countries. It is a staple food for millions of people around the world, particularly in arid and semi-arid regions where other crops may struggle to grow. Sorghum exhibits significant genetic diversity, providing a rich resource for breeding programs aimed at developing improved varieties with traits such as higher yield, disease resistance, and nutritional quality. The book enhances readers' understanding of classical breeding methods and their role in sorghum improvement. It also focuses on the contribution of OMICs and biotechnological approaches to sorghum improvement. Detailed information about the genetic and genomic resources of sorghum provided is helpful for the scientific community to utilize in sorghum breeding. Chapters highlight sorghum genome sequencing, transgenic and hybrid sorghum, and the application of genome editing. This book is useful to the breeding community, serving as a resource for interdisciplinary research groups such as geneticists, breeders, biotechnologists, bioinformaticians, and students, supporting them in accelerating their activities related to sorghum breeding.

Book Description
This new volume, Advances in Sorghum Science: Botany, Production, and Crop Improvement, provides an easy-to-read and comprehensive treatment of the sorghum crop. With the world’s production of sorghum topping over 55 million tons annually, sorghum is very important for as a staple dietary food for much of the world as a rich source of micronutrients and macronutrients, as an ingredient in the processing of many foods, and as a source of fodder. The authors of the volume provide detailed information on sorghum from several disciplines and bring together recent literature under one umbrella. The book covers the various aspects of the sorghum crop, starting from its origin, to its domestication, and going on to biotechnology of the crop. It describes sorghum production, ideotypes, botany, physiology, abiotic and biotic factors affecting crop productivity, methods of cultivation, postharvest management, grain quality analysis for food processing, improvement of sorghum crop, and research advancements in breeding and biotechnology. This valuable resource will be helpful to researchers and scientists working to understand the relation between various disciplines and the implementation of new methods and technology for crop improvement and higher productivity. The multi-pronged approach will help to enable the increase sorghum productivity to meet the world’s growing demands.

Book Description
During the past decade, there has been tremendous progress in maize biotechnology. This volume provides an overview of our current knowledge of maize molecular genetics, how it is being used to improve the crop, and future possibilities for crop enhancement. Several chapters deal with genetically engineered traits that are currently, or soon will be, in commercial production. Technical approaches for introducing novel genes into the maize genome, the regeneration of plants from transformed cells, and the creation of transgenic lines for field production are covered. Further, the authors describe how molecular genetic techniques are being used to identify genes and characterize their function, and how these procedures are utilized to develop elite maize germplasm. Moreover, molecular biology and physiological studies of corn as a basis for the improvement of its nutritional and food-making properties are included. Finally, the growing use of corn as biomass for energy production is discussed.

Book Description
The global population is projected to reach almost 10 billion by 2050, and food and feed production will need to increase by 70%. Wheat, maize and sorghum are three key cereals which provide nutrition for the majority of the world's population. Their production is affected by various abiotic stresses which cause significant yield losses. The effects of climate change also increase the frequency and severity of such abiotic stresses. Molecular breeding technologies offer real hope for improving crop yields. Although significant progress has been made over the last few years, there is still a need to bridge the large gap between yields in the most favorable and most stressful conditions.

Book Description
Nonrenewable energy resources deplete with the passage of time due to rapid increase in industrialization and population. Hence, countries worldwide are investing dearly in substitute energy resources like biofuel from miscellaneous set of feedstocks. Among the energy crops, sorghum serves as a model crop due to its drought tolerance, small genome size (730 Mb), high biomass, dry matter contents, quick growth, wide adaptability to diverse climatic and soil conditions and C4 photosynthesis. Sweet sorghum with high sugar content in stalk is an efficient feedstock for advanced biofuels and other bio-based products from sugars. However, high biomass sorghum has the utility as a feedstock for cellulosic biofuels. The enhanced yield of monomeric carbohydrates is a key to cheap and efficient biofuel production. The efficiency of lignocellulosic biofuels is compromised by recalcitrance to cell wall digestion, a trait that cannot be efficiently improved by traditional breeding. Therefore, scientists are looking for solutions to such problems in biomass crop genomes. Sorghum genome has been completely sequenced and hence this crop qualifies for functional genomics analysis by fast forward genetic approaches. This chapter documents the latest efforts on advancement of sorghum for biomass potential at morphological and molecular level by exploiting genomics approaches.
