Available in PDF, EPUB and Kindle. Book excerpt: This book serves the larger community of plant researchers working on the taxonomy, species delimitation, phylogeny, and biogeography of pseudo-cereals, with a special emphasis on amaranths. It also provides extensive information on the nutritive value of underutilized pseudo-cereals, the goal being to broaden the vegetable list. Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants. Most of the species are summer annual weeds and are commonly referred to as pigweed. Only a few are cultivated as vitamin-rich vegetables and ornamentals. The protein-rich seeds of a handful of species, known as grain amaranths, are consumed as pseudo-cereals. Amaranthusmanifests considerable morphological diversity among and even within certain species, and there is no general agreement on the taxonomy or number of species. Currently the genus Amaranthus is believed to include three recognized subgenera and 70 species. Amatanthus is considered to potentially offer an alternative crop in temperate and tropical climate. The classification of amaranths is ambiguous due to the lack of discrete and quantitative species-defining characteristics and the wide range of phenotypic plasticity, as well as introgression and hybridization involving weedy and crop species. It is a known fact that both vegetable and grain amaranths have evolved from their respective weed progenitors. There are more than 180 different weed species that are herbicide-resistant, and amaranths are considered to be leading members of the resistant biotypes. Amaranth species provide ample scope for investigating herbicide resistance mechanisms. Amaranths also show variability in terms of their mating behavior and germplasm, adaptability to different growing conditions, and wide range of variability in sexual systems, from monoecy to dioecy. A solid grasp of these parameters is essential to the future utilization of amaranths as super crops. There are quite a few amaranth research center and germplasm collections all over the world that maintain and evaluate working germplasms. To date, the genetic improvement of amaranths has primarily involved the application of conventional selection methods. But advances in genomics and biotechnology have dramatically enriched the potential to manipulate the amaranth genome, especially improving the amount and availability of nutrients. In conclusion, the book covers all aspects of amaranths, including their food value, significance as vegetables and pseudo-cereals, taxonomy, phylogeny, germplasm variability, breeding behavior and strategies, cultivation practices, and variability in terms of their sexual systems. It offers a valuable resource for all students, researchers and experts working in the field of plant taxonomy and diversity.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of genetic resources in amaranths, with a major focus on genomics, reverse, and forward genetics tools and strategies that have been developed for crop improvement. Amaranth is an ancient crop native to the New World. Interest in amaranths is being renewed, due to their adaptability, stress tolerance, and nutritional value. There are about 65 species in the genus, including Amaranthus caudatus L., A. cruentus L., and A. hypochondriacus L., which are primarily grown as protein-rich grains or pseudocereals. The genus also includes major noxious weeds (e.g., A. palmeri). The amaranths are within the Caryophyllales order and thus many species (e.g., A. tricolor) produce red (betacyanin) or yellow (betaxanthin) betalain pigments, which are chemically distinct from the anthocyanins responsible for red pigmentation in other plants. A. hypochondriacus, which shows disomic inheritance (2n = 32; n= 466 Mb), has been sequenced and annotated with 23,059 protein-coding genes. Additional members of the genus are now also been sequenced including weedy amaranths, other grain amaranths, and their putative progenitors.

Download or read book Genomic Designing for Biotic Stress Resistant Vegetable Crops written by Chittaranjan Kole and published by Springer Nature. This book was released on 2022-07-02 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic stresses cause yield loss of 31-42% in crops in addition to 6-20% during post-harvest stage. Understanding interaction of crop plants to the biotic stresses caused by insects, bacteria, fungi, viruses, and oomycetes, etc. is important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomics-assisted breeding and the recently emerging genome editing for developing resistant varieties in vegetable crops is imperative for addressing FPNEE (food, health, nutrition. energy and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing have facilitated precise information about the genes conferring resistance useful for gene discovery, allele mining and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to biotic stresses. The nine chapters each dedicated to a vegetable crop or crop-group in this volume will deliberate on different types of biotic stress agents and their effects on and interaction with crop plants; will enumerate on the available genetic diversity with regard to biotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; will brief on the classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; will enunciate the success stories of genetic engineering for developing biotic stress resistant varieties; will discuss on molecular mapping of genes and QTLs underlying biotic stress resistance and their marker-assisted introgression into elite varieties; will enunciate on different emerging genomics-aided techniques including genomic selection, allele mining, gene discovery and gene pyramiding for developing resistant crop varieties with higher quantity and better quality; and will also elaborate some case studies on genome editing focusing on specific genes for generating disease and insect resistant crops.

Download or read book Millets and Pseudo Cereals written by Mohar Singh and published by Woodhead Publishing. This book was released on 2020-09-20 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millets and Pseudo Cereals is the first comprehensive resource to focus on the potential crop improvements through genetic enhancements. The choice of food crop for a region is primarily determined by the conditions of climate and soil. Once labelled as orphan crops, millets and pseudo-cereals are now known as miracle grains due to their adaptation to harsh conditions and high nutritional quality. Small millets and pseudo-cereals are now seen to occupy special niches through their ability to adapt to challenging conditions. These crops have a comparative advantage in marginal lands where they withstand stress conditions and contribute to sustainable production. They also contribute to the diversity-richness and production stability of agro-ecosystems. Millets include sorghum, pearl millet, finger millet, foxtail millet, proso millet, barnyard millet, little millet and kodo millet while the other group which are not cereals but consumed as cereals and generally referred as pseudo-cereals comprises of grain amaranths, buckwheat and chenopods. Millets and Pseudo Cereals presents current information on the genetic architecture of important economic traits and the genomic resources for gene enabled breeding. This compilation contains information on the global status, available germplasm resources, nutritional value, breeding advancements, genomics applications and sustainability of agriculture through millets and pseudo-cereals cultivation. This book is a valuable resource for those conducting research and exploring new areas for advancing crop genetic understanding. - Explores the current challenges of pseudo-cereal production and how that can be overcome by developing genetic and breeding resources using appropriate germplasm - Provides holistic information on millets and pseudo-cereals - Features global perspectives from an international contributing team of authors
