Book Description
Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Book Description
an up-to-date authoritative reference designed primarily for students of economics but invaluable also to students of business and other social sciences and ideal for anyone who wants a brief explanation of an economic concept or institution The MIT Dictionary of Modern Economics is an up-to-date, authoritative reference designed primarily for students of business and other social sciences and ideal for anyone who wants a brief explanation of an economic concept or institution. In this fourth edition one entry in ten has been revised and one entry in twenty is new. Whereas the third edition increased the coverage of American institutions, this edition breaks new ground by including entries considered important from an Eastern European perspective. It also supplies comparative statistics on major economic variables for selected countries, describes the origins of widely used acronyms, and includes bibliographic references at the end of featured entries. The dictionary answers in a clear and concise way the enduring questions, which economists have considered for two centuries or more, as well as the issues of the moment, such as economic change in Europe, the problems of pollution, or the prospects for greater freedom of trade. With close to 2,800 entries it is comprehensive in its coverage of theory, national and international institutions, schools of thought, and important economists, including recent Nobel Prize winners. The dictionary was compiled initially by an experienced team of economists at Aberdeen University in the United Kingdom, and new authors have been recruited to provide international expertise, reflecting changes in the structure of the international economy. This fourth edition was prepared by John Cairns, Robert Elliott, Ian McAvinchey, and Robert Shaw, all of the Economics Department, University of Aberdeen.

Book Description
The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.
