Ecophysiology of root systems-environment interaction
There is a scarcity of detailed information regarding the ecophysiology of root systems and the way root system functioning is affected by both internal and external factors. Furthermore, global climate change is expected to increase the intensity of climate extremes, such as severe drought, heat waves and periods of heavy rainfall; in addition other stresses such as salinization of soils are increasing world-wide. Recently an increasing awareness has developed that understanding plant traits will play a major role in breeding of future crop plants. For example, there is increasing evidence that the traits of root systems are defined by the properties of individual roots. However, further knowledge on the functional importance of root segments and the molecular/physiological mechanisms underlying root system functioning and persistence is needed, and would specifically allow modifying (crop) root system functionality and efficiency in the future. Another major gap in knowledge is localized at the root-soil interface and in regard to the potential adaptive plasticity of root-rhizosphere interactions under abiotic stress and/or competition. It is currently unknown whether adaptations in microbe communities occur, for example due to modified exudation rates, and what are the subsequent influences on nutrient mobilization and uptake. Furthermore, uncovering the mechanisms by which roots perceive neighboring roots may not only contribute to our understanding of plant developmental strategies, but also has important implications on the study of competitive interactions in natural communities, and in optimizing plant performance and resource use in agricultural and silvicultural systems. In this Research Topic, we aimed to provide an on-line, open-access snapshot of the current state of the art of the field of root ecology and physiology, with special focus on the translation of root structure to function, and how root systems are influenced by interplay with internal and external factors such as abiotic stress, microbes and plant-plant interaction. We welcomed original research papers, but reviews of specific topics, articles formulating opinions or describing cutting-edge methods were also gladly accepted.
Advances in Ecophysiology of Root Systems-Environment Interaction
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.
Experimental Ecophysiology and Biochemistry of Trees and Shrubs
Author: Humberto González Rodríguez
language: en
Publisher: CRC Press
Release Date: 2020-11-01
The existence and competition of trees and shrubs to sustain and put forth growth under varied environmental conditions is dependent on the interactions that occur between the plant metabolic processes and the prevailing environmental conditions. In order to understand the productivity of trees and shrubs, it is a prerequisite to know the experimental techniques of these vital processes. This volume provides a comprehensive presentation of this topic. The first part of this book deals with various aspects of experimental ecophysiology and recent research results of studies on plant pigments, epicuticular wax, leaf nutrients, carbon fixation, all supported by literature. The second part of the volume describes various laboratory techniques such as diffusion, imbibition, calorimetry, atomic absorption, mineral nutrition, nutrition analysis of forage, litterfall chemistry, nutrient cycle, etc. The third and fourth parts deal with advances in the techniques in the development of ecophysiology. The book will serve as an important handbook and resource for students, faculty and teachers, technicians, and researchers and scientists involved in forest science dealing with ecophysiology and biochemistry of woody and crop plants.
