Book excerpt: Research progress in soil–root growth interactions has been slow due to the relative inaccessibility of roots in their natural environment and because root research cuts across the boundaries of soil science, ecology, crop science, and plant physiology, among others. Enhancing Understanding and Quantification of Soil–Root Growth Interactions takes on this challenge to solve society's growing problems in the conservation of quality water and soil resources. Researchers must come together and leverage our understanding of the rhizosphere to maximize efficient, sustainable use of limited water and soil nutrient resources. This is a serious calling—from addressing the critical needs in nations who cannot afford costly fertilizers, to the global challenge of enhancing soil carbon storage to reduce climate change effects of elevated carbon dioxide. This book brings together scientists from different disciplines, worldwide, together to encourage synthesis of transdisciplinary knowledge and further research and developments in the area of root–soil interactions.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the recent advancements in the role of various biomolecules in regulating root growth and development. Rhizobiology is a dynamic sub discipline of plant science which collates investigations from various aspects like physiology, biochemistry, genetic analysis and plant–microbe interactions. The physiology and molecular mechanisms of root development have undergone significant advancements in the last couple of decades. Apart from the already known conventional phytohormones (IAA, GA, cytokinin, ethylene and ABA), certain novel biomolecules have been considered as potential growth regulators or hormones regulating plant growth and development. Root phenotyping and plasticity analysis with respect to the specific functional mutants of each biomolecule shall provide substantial information on the molecular pathways of root signaling. Special emphasis provides insights on the tolerance and modulatory mechanisms of root physiology in response to light burst, ROS generation, agravitrophic response, abiotic stress and biotic interactions.

This book was released on 2011 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a challenging environment where resources, such as water, nutrients and air, are scarce and patchy. Plants and soil microorganisms have limited ability to move toward nutrient-enriched zones, compared with animals. Plants and roots have evolved to adapt and influence their physical environment as a way to create favorable conditions for its development. On the other hand, the structure of the soil controls its ability to receive, store and transmit water, to cycle carbon and nutrients, and to disperse anthropogenic and natural contaminants. As roots grow, soil structure changes; the pressure exerted produces a decrease in soil porosity and an increase in soil density, creating complex soil-root interactions. The scales of interest in the study of soil structure range from angstroms to kilometers. To study processes such as plant growth, root penetration, storage of water, and movement of nutrients, the most relevant scales range from microns to centimeters. Recent advances in X-ray micro-tomography (XMT) imaging have allowed the study of rhizosphere on spatial scale hitherto unreachable. This dissertation investigates utilization of XMT to study root-induced compaction on soil micro-structure and its effect on soil hydraulic properties. The current state of the art in soil-plant-root interactions using XMT is presented. Techniques to improve sensitivity of XMT images when roots are being scanned, are discussed. Feasibility of various segmentation techniques and examples of their use to quantify soil properties are addressed. XMT data quantification is then used in the study to feed numerical flow models. At bulk-scale, soil compaction has been associated with decrease in porosity and hydraulic conductivity and thus a reduction in soil productivity and fertility. However, at the aggregate scale, this study shows that natural root-induced compaction increases contact areas between aggregates, which may lead to an increase in unsaturated hydraulic conductivity of the soil adjacent to the roots. An analytical model to estimate the effect aggregate compaction on its effective hydraulic conductivity was developed. It was found that the effective hydraulic conductivity of a pair of aggregates, undergoing uniaxial stress, increased following a non-linear relationship as inter-aggregate contact area increased. Additionally, this study presents numerical modeling using actual XMT images of aggregated soil around a root surrogate to demonstrate how root-induced deformation increases unsaturated water flow towards the root, providing insight into the growth and water uptake patterns of roots in natural soils. Finally, this study presents a novel procedure that allowed coupling mechanical induced compaction with fluid flow simulation to model root-induced compaction in the rhizosphere. XMT images were used to describe in detail the rhizosphere microstructure. Then, finite element simulations were used to study the effect of an expanding root on root water uptake. The effect of increase aggregate connectivity, increase in effective hydraulic conductivity, root-soil contact area, and increase in local and global hydraulic gradient were evaluated. These results contribute to a better understanding of soil-waterroot interactions.

Available in PDF, EPUB and Kindle. Book excerpt: Despite their significance, root physiology and root function remain relatively underexplored in plant science research. Soil microorganisms, including mycorrhizae and bacteria, exert profound effects on nutrient cycling, root development, soil health, and overall plant productivity. In addition, different propagation methods can significantly influence root system architecture, further highlighting the complexity of underground dynamics. Various factors, such as nutrient levels, organic matter content, and management practices, impact both root and soil health. Suboptimal conditions can hinder root growth and affect plant physiology, ultimately affecting agricultural productivity. Recognizing the intricate interplay between roots, soil, and environmental factors is essential for implementing sustainable agricultural practices. This Special Issue of Plants aimed to bridge these knowledge gaps by integrating diverse research strands and spotlighting recent advancements in the ecophysiology of root systems and their interactions with the environment. By synthesizing insights from root biology, soil science, and agronomy, this collection seeks to advance our understanding of root-soil-environment interactions, paving the way for innovative strategies with which to enhance crop resilience and productivity in an everchanging world.
