Taxonomy Of Wild Tomatoes And Their Relatives Solanum Sect Lycopersicoides Sect Juglandifolia Sect Lycopersicon Solanaceae

This volume covers the advances in the study of tomato diversity and taxonomy. It examines the mapping of simple and complex traits, classical genetics and breeding, association studies, molecular breeding, positional cloning, and structural and comparative genomics. The contributors also discuss transcriptomics, proteomics, metabolomics, and bioin

This book examines the development of innovative modern methodologies towards augmenting conventional plant breeding, in individual crops, for the production of new crop varieties under the increasingly limiting environmental and cultivation factors to achieve sustainable agricultural production, enhanced food security, in addition to providing raw materials for innovative industrial products and pharmaceuticals. This Volume 9, subtitled Vegetable Crops: Fruits and Young Shoots, consists of 12 chapters focusing on advances in breeding strategies using both traditional and modern approaches for the improvement of individual vegetable crops. Chapters are arranged in 2 parts according to the edible vegetable parts. Part I: Fruits - Bell Pepper (Capsicum annuum L. var. grossum Sendt.), Chili pepper (Capsicum frutescens L.), Bitter gourd (Momordica charantia L.), Bottle gourd (Lagenaria siceraria (Molina) Standl.), Eggplant (Solanum spp.), Okra (Abelmoschus esculentus L.), Plantain (Musa paradisiaca L.), Sweet gourd (Cucurbita moschata Duch. ex Poir.), Melon (Cucumis melo L. Groups Dudaim and Flexuosus), Tomato (Solanum lycopersicum L.) and Zucchini (Cucurbita pepo L.) and Part II: Young shoots - Asparagus (Asparagus officinalis L.). The chapters were contributed by 43 internationally reputable scientists from 11 countries. Each chapter comprehensively reviews the modern literature on the subject and reflects the authors own experience.

Wild Germplasm for Genetic Improvement in Crop Plants addresses the need for an integrated reference on a wide variety of crop plants, facilitating comparison and contrast, as well as providing relevant relationships for future research and development. The book presents the genetic and natural history value of wild relatives, covers what wild relatives exist, explores the existing knowledge regarding specific relatives and the research surrounding them and identifies knowledge gaps. As understanding the role of crop wild relatives in plant breeding expands the genetic pool for abiotic and biotic stress resistance, this is an ideal reference on this important topic. Provides a single-volume resource to important crops for accessible comparison and research Explores both conventional and molecular approaches to breeding for targeted traits and allows for expanded genetic variability Guides the development of hybrids for germplasm with increased tolerance to biotic and abiotic stresses

Tomato cultivation is a major economic activity in many countries of the world. Thus, strategic efforts should be directed towards mitigating production constraints that limit overall yields and quality. In addressing some of these constraints, researchers are developing and using varieties of modern and innovative techniques to improve local tomato germplasm, make rapid genetic gains, and breed for varieties with resistance to biotic and abiotic stress. This book focuses on recent advances in genomics and genetic improvement of the tomato crop, and production systems, and center around the following themes: (i) disease and pest management in tomato production, and (ii) breeding tools and improvement of the tomato.

Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.
