    Abstract: The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.

    Abstract: This open access book shares impact stories – testimonies from various value chain actors who have been part of the Tropical Legumes (TL) projects, over the past twelve years. The Tropical Legumes projects led by ICRISAT in three parts (TLI, TLII and TLIII), constitute a major international initiative supported by the Bill & Melinda Gates Foundation (BMGF) and jointly implemented by the International Center for Tropical Agriculture (CIAT), International Institute of Tropical Agriculture (IITA) and National Agricultural Research Systems (NARS) partners from Sub-Saharan Africa and India. The project developed improved cultivars of common bean, cowpea, chickpea and groundnut (but also soya bean and pigeon pea cultivars in its initial phases) and delivers their seed to smallholders in BMGF-focus areas. It also strengthens the NARS and CGIAR's breeding programs and seed platforms to enhance their ability to deliver high and sustained outputs to smallholder farmers. The book compiles the experiences of a diversity of actors within the grain legume value chains, with a focus on groundnut and common beans in Tanzania and Uganda, groundnut and cowpea in Nigeria, and groundnut in Ghana. All stakeholders involved share their thoughts on being part of a decade-long development project family. National agricultural research institutes, knowledge brokering organizations, NGOs, public and private seed companies, agro-dealers, individual seed entrepreneurs, farm-implement makers, farmer cooperatives, farmer groups, individual men and women farmers, middlemen, processors, traders and consumers were all involved in this project, and as such this book provides valuable insights for development workers, technical staff, and project managers.

    Description: Abiotic stresses are the major cause that limits productivity of crop plants worldwide. Plants have developed intricate machinery to respond and adapt over these adverse environmental conditions both at physiological and molecular levels. Due to increasing problems of abiotic stresses, plant biotechnologists and breeders need to employ new approaches to improve abiotic stress tolerance in crop plants. Although current research has divulged several key genes, gene regulatory networks and quantitative trait loci that mediate plant responses to various abiotic stresses, the comprehensive understanding of this complex trait is still not available. This e-book is focused on molecular genetics and genomics approaches to understand the plant response/adaptation to various abiotic stresses. It includes different types of articles (original research, method, opinion and review) that provide current insights into different aspects of plant responses and adaptation to abiotic stresses.

    Notes: Abstract  Antinuclear autoantibodies are a hallmark of systemic lupus erythematosus (SLE). Autoantibodies to HRES-1/p28, a 28 000 M r nuclear protein, commonly occur in patients with SLE. HRES-1 is a single-copy endogenous retroviral element mapped to human Chromosome 1 at q42. A polymorphic Hin dIII site defines two different allelic forms of the genomic locus. The HRES-1/1 probe [5.5 kilobases (kb)] anneals to three polymorphic fragments and three genotypes can be differentiated: I, 5.5 kb fragment only; II, 3.7 kb and 1.8 kb fragments only; and III, all three polymorphic fragments. By cloning of the HRES-1 locus from homozygous type I and type II human DNA samples, the polymorphic Hin dIII site was identified as a G to C transition at position 653 of the long terminal repeat region. Family studies showed that Hin dIII genotypes of the HRES-1 locus are inherited in a Mendelian pattern. The relative frequency of genotype I with respect to genotype III was 3.1-fold lower in patients with SLE (14 : 40=0.35) in comparison to 100 ethnically matched control donors (47 : 43=1.09;P=0.0084). Frequency of genotype I vs genotype II alleles was lower in SLE (68/52) than in normal donors (137/63;P=0.033), suggesting that a genotype I allele of the HRES-1 locus may be protective against SLE. Western blot seroreactivity with recombinant HRES-1/p28 was noted in 4/14 (29%) of genotype I patients and 13/19 (68%) of genotype III patients (P〈0.025). These data raise the possibility that the HRES-1 element or a gene in linkage disequilibrium with this genomic locus may influence autoimmunity in SLE.

    Notes: A procedure is proposed for the extraction of molar Larmor diamagnetic susceptibilities χL=−N0e2〈r2〉/(6mc2) (N0 is the Avogadro number) for closed-shell atomic and molecular systems, starting exclusively from their electron momentum densities derived from experimental or theoretical Compton profile data. This procedure is essentially founded on a transcription of the coordinate-space nonlocal-density approximation (NLDA) of Gadre and Chakravorty [J. Chem. Phys. 86, 2224 (1987)] to momentum space. Numerical tests of this scheme to a variety of closed-shell systems yield decent estimates of their 〈r2〉 values which compare well with their experimental or theoretical counterparts.

    Notes: Novel rigorous upper and lower bounds, at primitive level, to general electron-repulsion integrals (ERIs) involving Gaussian basis sets have been derived and interconnections with the earlier works in the literature are brought out. New optimal strategies for a preemptive elimination of insignificant ERIs at atom and contraction levels are discussed and tested, resulting in a significant reduction in CPU time. Similar analysis is carried out for the computation of the molecular electrostatic potential for the first time in the literature, leading to a marked savings in computer time.

    Notes: First-order united atom perturbation theory calculations of very short-range interactions between rare gas atoms are reported. These should prove useful because many of the state-of-the-art potentials have a spurious maximum at very small distances. Fits to these calculations are provided along with interpolation functions to smoothly connect them to the best available potentials for larger distances. Thirring bounds are computed for the first time. They readily reveal gross inadequacies in some potentials at very short range, but they are too weak to distinguish among potentials with the correct limiting behavior at R=0.
