Cultivated cotton fiber has undergone a dramatic transformation from the short, brown trichomes found in closely related wild species to the economically important long, white trichomes grown throughout the world today. Very little is known about the development of wild cotton fiber or the developmental differences between wild and cultivated cotton fibers. This study looks at the amount of fiber on the ovule coat, nucleus position, presence of the vacuole, fiber size, fiber shape, and the driving force behind size and shape differences in four taxa-Gossypium raimondii (wild D-genome), G. herbaceum var. Wagad (cultivated A-genome), G. hirsutum var. yucatanense (wild tetraploid), and G. hirsutum var. Maxxa (cultivated tetraploid)-using a variety of morphometric and statistical methods. Significant changes in the timing of developmental events show a synchronization of fiber development in G. hirsutum var. Maxxa compared to all other taxa, while the other cultivar, G. herbaceum var. Wagad shows a delay in developmental events and the wild taxa have timing intermediate to the cultivars. The phylogenetic relationship is found to be the primary driving force behind size and shape, however, domestication becomes a force at later days of development.

Cotton fiber is the most important natural fiber used in the textile industry. The physical structure and chemical compositions of cotton fibers have been extensively studied. Newer high speed spinning instruments are being deployed around the world that demand longer, stronger and finer fibers. Consequently, genetic improvement in fiber quality has been stressed. With improvement in fiber quality has come the realization that further fiber improvement will require a better understanding of fiber development and biology. As a consequence, cotton fiber developmental biology, genetics and genomics have become focal points in the cotton research community. As the longest single-celled plant hair, cotton fiber has been used as an experiment model to study trichome initiation and elongation in plants. This book provides a comprehensive update on cotton fiber physics, chemistry and biology that form the three sections of the book. In the physics section, the physical structure of cotton fiber is first illustrated in great detail. Then a suite of fiber properties and their measuring methods are described. The pros and cons of each method are outlined. New methods to measure physical properties of single fiber and young developing fibers are included. In the chemistry section, the chemical compositions of cotton fibers are described in detail. This knowledge is necessary for efficient modification of cotton fibers for better and broader utilization. The advancement in cotton fiber modification using chemical and enzymatic methods opened new ways to utilize cotton fibers. In the biology section, the book first introduces the utilization of naturally occurring color cottons. Color cottons possess unique attributes such as better fire retardant ability. Advancement in understanding fiber color genetics and biochemical pathways and new utilization of color cottons are discussed. Recent technological advancements in molecular biology and genomics have enabled us to study fiber development in great depth. Many genes and quantitative trait loci related to fiber quality attributes have been identified and genetically mapped. Some of these genes and QTLs are being used in breeding. Progresses in cotton fiber improvement using breeding and biotechnology are discussed in the last chapter. This book serves as a reference for researchers, students, processors, and regulators who either conduct research in cotton fiber improvement or utilize cotton fibers.

The origin of agriculture is one of the defining events of human history. Some 11-10,000 years ago bands of hunter-gatherers started to abandon their high-mobility lifestyles in favour of growing crops, and the creation of settled, sedentary communities. This shift into agricultural lifestyle triggered the evolution of complex political and economic structures, and technological developments, and ultimately underpinned the rise of all the great civilisations of recent human history. Domestication of Plants in the Old World reviews and synthesises the information on the origins and domestication of cultivated plants in the Old World, and subsequently the spread of cultivation from southwest Asia into Asia, Europe, and North Africa, from the very earliest beginnings. This book is mainly based on detailed consideration of two lines of evidences: the plant remains found at archaeological sites, and the knowledge that has accumulated about the present-day wild relatives of domesticated plants. This new edition revises and updates previous data and incorporates the most recent findings from molecular biology about the genetic relations between domesticated plants and their wild ancestors, and incorporates extensive new archaeological data about the spread of agriculture within the region. The reference list has been completely updated, as have the list of archaeological sites and the site maps. This is an advanced, research level text suitable for graduate level students and researchers in the fields of crop science, agriculture, archaeology, botanical archaeology, and plant biotechnology. It will also be of relevance and use to agricultural historians and anyone with a wider interest in the rise of civilisation in this region.

This book discusses innovative methods for mining information from images of plants, especially leaves, and highlights the diagnostic features that can be implemented in fully automatic systems for identifying plant species. Adopting a multidisciplinary approach, it explores the problem of plant species identification, covering both the concepts of taxonomy and morphology. It then provides an overview of morphometrics, including the historical background and the main steps in the morphometric analysis of leaves together with a number of applications. The core of the book focuses on novel diagnostic methods for plant species identification developed from a computer scientist’s perspective. It then concludes with a chapter on the characterization of botanists' visions, which highlights important cognitive aspects that can be implemented in a computer system to more accurately replicate the human expert’s fixation process. The book not only represents an authoritative guide to advanced computational tools for plant identification, but provides experts in botany, computer science and pattern recognition with new ideas and challenges. As such it is expected to foster both closer collaborations and further technological developments in the emerging field of automatic plant identification.
