Special Issue Information

Dear Colleagues,

Global climate change is increasing the frequency and severity of stress, thus threatening food production around the world. Plants have evolved to cope with these stresses by triggering growth and development changes, and phytohormones act as all-encompassing regulators in this process. As the belowground organ of the plant, roots are fundamentally important for growth and development as they anchor the plant to its growth substrate, facilitate water and nutrient uptake from the soil, and sense and respond to environmental signals such as biotic and abiotic stresses. Upon exposure to stress, roots change their architecture to help plants survive under stressful conditions. Thus, root plasticity is a good model for studying plant response to stressful environments, and more and more scientists believe that modulating root growth and development provides a potentially useful approach to improve plant stress tolerance without yield penalties. Research on phytohormones in plant root development and stress tolerance has been intensively carried out. This Special Issue of Plants aims to bring together inspiration from multiple research studies and highlight the function of phytohormones in crop root development and stress tolerance.

Plants live in constantly changing environments that are often unfavorable or stressful. Root development strongly affects plant growth and productivity, and the developmental plasticity of roots helps plants to survive under abiotic stress conditions. This review summarizes the progress being made in understanding the regulation of the phtyohormone ethylene in rice root development in response to abiotic stresses, highlighting the complexity associated with the integration of ethylene synthesis and signaling in root development under adverse environments. Understanding the molecular mechanisms of ethylene in regulating root architecture and response to environmental signals can contribute to the genetic improvement of crop root systems, enhancing their adaptation to stressful environmental conditions.
