Legume Breeding in Transition: Innovation and Outlook


Book Description

Legumes (family Fabaceae) comprise a diverse range of crops grown worldwide, which are important constituents of sustainable agriculture and harbour a role in improving human and livestock health. Legumes serve as a rich source of plant-based proteins, rank second in nutrition value after cereals, and are ideal to supplement a protein-deficient cereal-based human diet. Legumes also provide other essential services to agriculture through their ability to fix atmospheric nitrogen, recycle nutrients, enhance soil carbon content, and diversify cropping systems. Legume production and seed quality are affected by a range of biotic (pests, insect diseases, and weeds) and abiotic stresses (drought, heat, frost, and salinity). In addition to this, rapidly changing climate, shrinking arable land, erratic rainfalls, and depleting water and other natural resources impact legume production and threaten food and nutrition security worldwide. Persistent demand for legume crops is existing to fulfil the food requirements of an ever-growing human population. Therefore, legume breeders and geneticists have employed different conventional and modern breeding strategies to improve yield, resistance to biotic and abiotic stresses, grain quality, and nutritional and nutraceutical properties. Conventional breeding strategies are laborious, time consuming, expensive, and inefficient to achieve the desired goals. However, advanced breeding techniques such as alien gene introgression, genomics-assisted breeding, transgenic technology, speed breeding, association and mapping studies, genome editing, and omics will contribute to sustainable agriculture and food security.




Legume Crop Wild Relatives


Book Description

Grain legume crops are an important component of global food and nutritional security and help in maintaining agro-ecological systems. They fix atmospheric nitrogen via the root-inhabiting rhizobacteria, thereby minimising the harmful effects caused by the excessive application of synthetic nitrogenous fertilizers in the soil environment. There has been less focus on legume crop wild relatives for harnessing their potential traits and novel gene(s) to incorporate them into the cultivated legumes for developing climate-resilient grain legumes. In this edited book, we will highlight the importance of various potential traits of crop wild relatives, which are yet to be properly harnessed for designing future climate-resilient grain legumes. We also update how advances in molecular genetics and genomics have enabled the underpinning of several candidate genes/genomic regions in various crop wild relatives harbouring adaptive traits that confer climate resilience in grain legumes. Readers will benefit from new information on various crop wild relatives in grain legumes and how these wild relatives could be explored for novel climate resilience genes for developing future climate-resilient legume crops. They will gain an understanding of how genomic advances (genome sequence, pan genomes) have uncovered the novel genomic regions attributed to climate resilience in various grain legumes. Finally, the critical role of these wild relatives in maintaining the lost gene(s) due to the domestication process will be discussed. Comprehensive information on conventional breeding, advanced breeding, and recent advances in genomics covering all the major crop wild relatives of legumes is not available in a single book. Thus, this book will provide readers with the latest updates on various information covering all aspects of wild species of legumes.




Legume Crop Genomics


Book Description

Demonstrating the quantum leap genomics represents in technology, this book documents the initial research strategies, the development of genomic tools and resources, and the legume-community consensus on the research objectives that will guide the genomic characterization of major legume crops. The book presents this technical theme in a manner that helps readers answer the question, "What is genomics?" And finally, this book helps readers formulate an opinion on the question, "Why is genomic research needed?" The application of this technology in legume crop enhancement will ensure that U.S. agriculture remains competitive in domestic and global markets for legumes and legume crop products.




Genetic Improvement of Minor Crop Legumes


Book Description

Minor crop species and their wild relatives are resilient to multiple environmental stressors and are a great potential resource for promoting global food and nutritional security. However, since many of these species are deficient in a few or several desirable domestication traits which reduce their agronomic value, further work on their trait improvement is required in order to fully exploit their food benefits. Thus, to some extent, a minor crop may be regarded as semi-domesticated species based on the extent to which it is deficient in a number of agronomically significant domestication traits. Quite recently, research has revealed prospects of creating new crops out of wild plant species via de novo domestication. Minor crops deficient in desirable domestication traits as well as their wild relatives can possibly be subjected to such a systematic process of redomestication and de novo domestication in order to increase their food, nutritional, or raw material utilization value. This review discusses the feasibility of employing CRISPR/Cas-mediated genome editing techniques for the genetic enhancement of minor legumes and de novo domestication of their wild relatives.

Grain Legumes


Book Description

​​​This book is devoted to grain legumes and include eight chapters devoted to the breeding of specific grain legume crops and five general chapters dealing with important topics which are common to most of the species in focus. Soybean is not included in the book as it is commonly considered an oil crop more than a grain legume and is included in the Oil Crops Volume of the Handbook of Plant Breeding.​Legume species belong to the Fabaceae family and are characterized by their fruit, usually called pod. Several species of this family were domesticated by humans, such as soybean, common bean, faba bean, pea, chickpea, lentil, peanut, or cowpea. Some of these species are of great relevance as human and animal food. Food legumes are consumed either by their immature pod or their dry seeds, which have a high protein content. Globally, grain legumes are the most relevant source of plant protein, especially in many countries of Africa and Latin America, but there are some constraints in their production, such as a poor adaptation, pest and diseases and unstable yield. Current research trends in Legumes are focused on new methodologies involving genetic and omic studies, as well as new approaches to the genetic improvement of these species, including the relationships with their symbiotic rhizobia.




Advances in Legume Research


Book Description

Legumes crops have an extraordinary importance for the agriculture and the environment. In a world urgently requiring more sustainable agriculture, food security and healthier diets the demand for legume crops is on the rise. The International Legume Society (http://ils.nsseme.com) organizes a triannual series of conferences with the goal to serve as a forum to discuss interdisciplinary progress on legume research. The Second International Legume Society Conference (ILS2) hosted in October 2016 at Troia, Portugal was the starting point for the Research Topic “Advances in Legume Research” in FiPS, that was also open to spontaneous submissions.
