First published in 1987 this book looks at root development and functions. Besides affecting the development of roots directly, the physical environment also influences the organisms associated with roots and thus affects their function. The papers presented in this volume pay equal attention to root development and root function in relation to the whole range of environmental factors including temperature, light, water, aeration, gravity and the mechanical strength of the soil. Consideration is also given to the effects of some of these factors on mycorrhizae and nitrogen-fixing bacteria. The final chapter reviews some of the main themes raised in the volume and indicates the way that research at the cellular and tissue levels may progress in the future.

This book contains the majority of the presentations of the Second International Symposium on the Biology of Root Formation and Development that was hcld in Jerusa lem, Israel, June 23---28, 1996. Following the First Symposium on the Biology of Adventi tious Root Formation, held in Dallas. USA, 1993, we perceived the need to include all kinds of roots, not only the shoot-borne ones. The endogenous signals that control root formation. and the subsequent growth and development processes, are very much alike, re gardless of the sites and sources of origin of the roots. Therefore, we included in the Sec ond Symposium contributions on both shoot-borne (i.e., adventitious) roots and root-borne (i.e., lateral) roots. Plant roots have remained an exciting and an intriguing field of sciencc. During thc years that followed the first symposium, an exceptional proliferation of interest in root biology has developed, associated with the intensive research activity in this field and the contemporary developments in the understanding of root function and development. New methods have been applied, and old ideas and interprctations werc rccxamined. Alto gether, it became necessary to update our viewpoints and to expand them.

Der Pflanzenbewuchs und die durchwurzelte Bodenschicht nehmen eine zentrale Stellung in terrestrischen Ökosystemen ein. Die Bedeutung der im Wurzel-Boden-Kontaktraum ablaufenden komplexen Prozesse für die Pflanzen- und Bodenentwicklung wurde lange Zeit nicht ausreichend erkannt. Diese grundlegenden Prozesse sind inzwischen als so genannte "Hidden Half" Gegenstand zahlreicher Untersuchungen. Ihre Aufklärung ist eine Voraussetzung für Vermeidung, Indikation und Behebung von Umweltschäden. Sie können Richtlinien für einen ökologisch orientierten Maßnahmenkatalog sowie für eine nachhaltige ressourcenschonende Landbewirtschaftung liefern. Dieses Buch leistet einen Beitrag zum besseren Verständnis des Wirkungsgefüges und der Steuermechanismen im Wurzel-Boden-Interface.

The decade since the publication of the third edition of this volume has been an era of great progress in biology in general and the plant sciences in particular. This is especially true with the advancements brought on by the sequencing of whole genomes of model organisms and the development of "omics" techniques. This fourth edition of Plant Roots: The Hidden Half reflects these developments that have transformed not only the field of biology, but also the many facets of root science. Highlights of this new edition include: The basics of root research and their evolution and role in the global context of soil development and atmosphere composition New understandings about roots gained in the post-genomic era, for example, how the development of roots became possible, and the genetic basis required for this to occur The mechanisms that determine root structure, with chapters on cellular patterning, lateral root and vascular development, the molecular basis of adventitious roots, and other topics Plant hormone action and signaling pathways that control root development, including new chapters on strigolactones and brassinosteroids Soil resource acquisition from agricultural and ecological perspectives Root response to stress, with chapters that address the impact of the genomic revolution on this topic Root-rhizosphere interactions, from beneficial microorganisms to detrimental nematodes Modern research techniques for the field and the lab Each chapter not only presents a clear summation of the topic under discussion, but also includes a vision of what is to be expected in the years to come. The wide coverage of themes in this volume continues the tradition that makes this work recognized as a fundamental source of information for root scientists at all levels.

Growth and Development of Trees, Volume II: Cambial growth, Root Growth, and Reproductive Growth describes the important features of growth and development of trees and other woody plants during their life cycles. This nine-chapter book highlights the significant changes that take place in vegetative and reproductive growth as woody plants progress from juvenility to adulthood and, finally, to a senescent state. The first four chapters cover the growth of tree cambium, which is a layer of delicate meristematic tissue between the inner bark or phloem and the wood or xylem. These chapters examine the variation, control, and measurement of cambial growth. The next two chapters look into the growth mechanism of specialized and modified root systems, such as aerial, grafted, knee, and nodulated roots, root buttresses, mycorrhiza, and pneumatophores. These chapters also discuss the distribution and growth characteristics of roots of woody plants. Other chapters explore the significant changes and features during flowering and fruit, cone, and seed development. The last chapter considers some aspects of internal and external control of reproductive growth at critical stages of development. Some practical methods for stimulating fruit and seed production by trees are also provided. This book will be of great value to arborists, foresters, horticulturists, plant ecologists, plant physiologists, plant anatomists, tree breeders and geneticists, plant pathologists, entomologists, soil scientists, meteorologists, and landscape architects. It is also intended for upper level undergraduate and graduate students.

The functional characterization of a key enzyme in the phosphatidylinositol (PI) signaling pathway in the model plant Arabidopsis thaliana is the focus of the research summarised in this thesis. Moreover, a particular focus is the exploration of the biological functions of Arabidopsis phophatidylinositol monophosphate 5-kinase 2 (PIP5K2) which catalyzes the synthesis of phophatidylinositol (4,5) bisphosphate, the precursor of two important second messengers (inositol 1,4,5-trisphosphate and diacylglycerol). Through molecular and genetic approaches, the author isolated and characterized the expression pattern, physiological functions and the underlying mechanism of Arabidopsis PIP5K2. It is found that PIP5K2 is involved in regulating lateral root formation and root gravity response through modulating auxin accumulation and polar auxin transport and also plays a critical role in salt tolerance. These findings shed new light on the crosstalk between PI signaling and auxin response, both of which have crucial regulatory roles in plant development.

Root hairs increase the surface area of roots to the point that they can comprise a significant portion of the entire absorptive surface of root systems. Root hairs do this at rather minimal carbon cost, because of their range of sizes. A question posed by the author is whether, besides high rates of respiration, roots have any additional roles in the function of the rhizosphere. He presents hypotheses on this subject from a holistic point of view. The book covers the occurrence, life history, cytology, anatomy, morphology and physiology of root hairs. It also analyses the critical role of root hairs in the development of nodules - rhizobial and actinorrhizal in the process of symbiotic nitrogen fixation. Less well known, but still important, is the role of root hairs in mycorrhizal symbioses and their importance for the mineral nutrition of plants.

Relacao da agua com o desenvolvimento da raiz do sorgo granifero nos primeiros estagios de crescimento. O trabalho procurou determinar a resposta das plantas jovens a mudanca de conteudo de umidade do solo e reducao da densidade de crescimento da raiz. Sob estas condicoes o desenvolvimento do sistema da raiz, crescimento da folha, area da folha e potencial de agua na folha foram estudados. A possibilidade do estagio sensitivo, no qual o desenvolvimento da raiz da planta pode causar stresse hidrico sem levar em conta o conteudo de agua no solo causando um minimo de potencial de agua na folha seguido por uma recuperacao gradual foi explorado.
