Genetic and Genomic Resources of Grain Legume Improvement
The Asian Vigna in the subgenus Ceratotropis, with several recognized species distributed across Asia, constitute an economically important group of cultivated and wild species for which a rich diversity occurs in India and other parts of Asia. Taxonomically, cultigen and conspecific wild forms are recognized in all major cultivated Asiatic pulses, mung bean (V. radiata), urd bean (V. mungo), rice bean (V. umbellata) and azuki bean (V. angularis) except for moth bean (V. aconitifolia), which has retained a wild-type morphology. The cultivated species V. radiata and V. mungo are of Indian origin. The domestication of V. aconitifolia is also apparently Indian, whereas that of V. angularis and V. umbellata is Far Eastern. A comprehensive review on origin,distribution, diversity, evaluation and utilization including genomic resources of Asian Vigna species is described in the chapter. The compilation will be a valuable reference for agriculturists, conservationists, taxonomists and other researchers interested in the genetic and genomic resources management of Asian Vigna species.
Broadening the Genetic Base of Grain Legumes
Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In ord...

Genetic and Genomic Resources of Grain Legume Improvement
Grain legumes mainly consisting of common bean, pea, chickpea, faba bean, cowpea, lentil, pigeon pea, peanut, Asian Vigna species, grass pea and horsegram are under cultivation in a considerable area worldwide. With their higher protein content and symbiotic nitrogen-fixing bacteria in root nodules enabling them to fix their own nitrogen, reducing the fertilizer use in agriculture has become very important for the production systems. For most of these important grain legumes, a large number of germplasm accessions were characterized and evaluated for various agro-morphological traits, including biotic, abiotic and quality parameters. Core and mini-core collections have also been developed for the majority of grain legumes; they were further evaluated for different parameters. From these genetic resources, potential donors of desirable traits have been selected after evaluation and characterization and have been utilized in the genetic improvement of cultivars. Current available genomic resources and technologies can facilitate allele mining for novel traits of interest and incorporation from wild relatives into elite domestic genetic backgrounds.
Proceedings of the International Conference on Plant Developmental Biology
These conference proceedings cover recent advances in the field of developmental biology in plants. The developmental processes explored here are mainly focused on photomorphogenesis, flowering time control and the circadian clock. The book will appeal to biologists, academicians, scientists, researchers and students, as well as readers exploring the role of light in controlling various indispensable physiological processes in plants, such as flowering, circadian clock regulations and hormonal regulations. The volume also emphasises several interrelated developmental processes, such as disease development, and molecular events, including the degradation of proteins.

Cowpea (Vigna unguiculata), an indigenous legume to sub-Saharan Africa, is mainly grown in the dry savanna areas as an intercrop with millets, sorghum, groundnut and maize. Cowpea grains rich in protein are consumed in different forms in several parts of the tropics. The average grain yield of cowpea in West Africa is approximately 492kg/ha, which is much lower than its potential yields. This low productivity is due to a host of diseases, insects, pests, parasitic weeds, drought, poor soils and low plant population density in farmers’ fields. Ex situ collection of over 15,000 accessions of cowpea and wild Vigna germplasm from different parts of the world were assembled in the IITA gene bank. These genetic resources have been explored to identify new traits and to develop elite cowpea varieties. Many cowpea varieties with high yield potential have been developed and adopted by the farmers. Efforts are continuing to develop better performing varieties using conventional breeding procedures, while molecular tools are being developed to facilitate progress in cowpea breeding.

Chickpea is an important protein-rich crop with considerable diversity present among 44 annual Cicer species. A large collection of chickpea germplasm including wild Cicer species has been conserved in different gene banks globally. However, the effective and efficient utilization of these resources is required to develop new cultivars with a broad genetic base. Using core and mini-core collections, chickpea researchers have identified diverse germplasm possessing various beneficial traits that are now being used in chickpea breeding. Further, for chickpea improvement, the genus Cicer harbours alleles/genes for tolerance/resistance to various abiotic and biotic stresses as well as for agronomic and nutrition-related traits. Recent advances in plant biotechnology have resulted in developing large number of markers specific to chickpea in addition to technological breakthrough in developing high-throughput genotyping platforms for unlocking the genetic potential available in germplasm collections.

Pigeon pea (Cajanus cajan (L.) Millspaugh) is an important grain legume crop grown in tropical and subtropical regions of the world. Though pigeon pea has a narrow genetic base, vast genetic resources are available for its genetic improvement. Evaluation of small subsets, such as core (10% of the whole collection) and mini-core collections (about 1% of the entire collection), has resulted in the identification of promising diverse sources for agronomic and nutrition-related traits as well as resistance/tolerance to important biotic/abiotic stresses for use in pigeon pea improvement programmes. Wild relatives of pigeon pea are the reservoir of many useful genes, including resistance/tolerance to diseases, insect pests and drought and good agronomic traits, and also have contributed to the development of cytoplasmic male sterility systems for pigeon pea improvement. Availability of genomic resources, including the genome sequence, will facilitate greater use of germplasm to develop new cultivars with a broad genetic base.

Horse gram is a pulse and fodder crop native to Southeast Asia and tropical Africa. India is the only country cultivating horse gram on a large acreage, where it is being used for human food. It is a versatile crop and can be grown from near sea level to 1800m. It is a drought-tolerant crop plant and can be grown successfully with low rainfall. Global efforts to conserve the horse gram germplasm are lacking, as the crop does not attract much notice. The US Department of Agriculture (USDA) Germplasm Resources Information Network (GRIN) conserved only 35 accessions of Macrotyloma uniflorum in its gene bank. Protabase (Plant Resources of Tropical Africa Database), responsible for germplasm cons...
