In recent years, global warming and environmental degradation have been causing extreme weather world-wide, including very hot summers and cold winters, floods, and outbreaks of pests and diseases. The development of modern industry has also created new challenges for plants, such as heavy metal stress, micro- or nano-plastics, pesticides, fragrances, antibiotics, and plasticizers. These biotic and abiotic stresses negatively affect the growth, development, reproduction, and yield of agricultural and horticultural crops. While the effects of these stresses on plants are extensively studied and plants have evolved complex tolerance mechanisms, the roles of reactive oxygen species (ROS) and phytohormones in crops under biotic and abiotic stress conditions remain underestimated. Therefore, there is an urgency to understand the functions of ROS and phytohormones to reveal more insights into the mechanisms of stress-tolerant crops, thus ensuring the security of agricultural and horticultural crops.
Plants have evolved multiple systems to cope with adverse environmental conditions, including stress perception, signal transduction, transcriptional changes of stress-related genes and synthesis of stress responsive proteins and phytohormones. The relationship between plant stress-tolerance and these underlying mechanisms is essential for crop breeding and production. ROS and phytohormones are repetitively shown to be critical for plants under stress conditions. However, many aspects regarding ROS and phytohormones in crops remain obscure. New research on the physio-biochemical, molecular responses and stress-responsive pathways in biotic and abiotic-stressed crops will provide novel insights into plant mechanisms under adverse conditions. This Research Topic explores the connection between stress tolerance and underlying plant mechanisms that will aid future crop engineering and ensure adequate crop production.
This Research Topic incorporates the contributions of scientists who study plant physiology, plant pathology, biochemistry, ecotoxicology and environmental safety, to unveil the roles of ROS and phytohormones in crop and horticultural plants under biotic and abiotic stress conditions. We aim to discover new insights regarding stress tolerance mechanisms in plants under global environmental challenges. Authors are invited to submit (mini) reviews, original research, opinions and methods related to, but not exclusively limited to, the following:
• Stress perception mechanisms and stress downstream activations of ROS and/or phytohormones
• Contributions of novel pathways and phytohormones in modulating biotic and abiotic stress tolerance
• Physiological, biochemical (including ROS and/or phytohormones) and molecular studies of crop responses to biotic and/or abiotic stresses
• ROS and phytohormone changes at the plant level in response to biotic and/or abiotic stresses
• Genetic engineering and genome editing for biotic and/or abiotic stress tolerance
• Biotechnological approaches to study ROS and/or phytohormones in plants
• Mechanisms of stress-tolerance enhancement by mineral elements, biochar, nano-materials and/or phytohormones in plants
