Other chapters focus on Genetic Diversity for Developing Climate-resilient Wheats to Achieve Food Security Goals and A Century of Subclover: Lessons for Sustainable Intensification from a Historical Review of Innovations in Subterranean Clover Seed Production.

Sea urchins and other echinoderms, which have been studied intensively by developmental biologists for more than a century, are currently among the most prominent models for elucidating the genomic regulatory processes that control embryogenesis and the evolution of those processes. This volume contains reviews from the world's leading researchers who are using echinoderms to address these questions. Chapters focus on gene regulatory networks that drive the differentiation and morphogenesis of major embryonic tissues such as the skeleton, muscle, nervous system, immune system, pigment cells, and germ line, and on evolutionary insights from comparative studies of these networks across echinoderms and other taxa. Other chapters comprehensively review the architecture and evolution of the cell signaling pathways that establish the early embryonic axes and on recent evolutionary changes in gene networks that have led to dramatic changes in the life history modes of echinoderms. This volume provides a comprehensive, current picture of exciting research at the interface between developmental genomics and evolution from one of the research communities leading this work.

Emerging Plant Growth Regulators in Agriculture: Roles in Stress Tolerance presents current PGR discoveries and advances for agricultural applications, providing a comprehensive reference for those seeking to apply these tools for improved plant health and crop yield. As demand for agricultural crops and improved nutritional requirement continue to escalate in response to increasing population, plant researchers have focused on identifying scientific approaches to minimize the negative impacts of climate change on agriculture crops. Among the various applied approaches, the application of plant growth regulators (PGRs) have gained significant attention for their ability to enhance stress tolerance mechanisms. This book was developed to provide foundational and emerging information to advance the discovery of novel, cost-competitive, specific and effective PGRs for applications in agriculture.

Analysis of Chemical Residues in Agriculture presents a focused, yet comprehensive guide on how to identify, evaluate and analyze the wide range of chemicals that impact our food production system. The book presents a variety of analytical technologies and methods in order to help professionals, researchers, and graduate and undergraduate students understand chemical residues in agriculture and apply them to applications for the detection and quantification of chemical residues - both organic and inorganic - in several agricultural matrices, including crops, fruits, meat, food, feed, soil and water. Agriculture remains one of the most strategic sectors for the global economy and well-being. However, it is seen as a source of environmental and health concerns mainly due to the high amount of pesticides and fertilizers used in production systems around the world; moreover, a thorough understanding of the topic is necessary when we consider livestock production systems also apply large amounts of veterinary drugs to treat illness and promote increases in productivity.
