About this Research Topic
Up-to-date scientific efforts are welcome to be delivered into this topic for a comprehensive understanding of the physiological and molecular effects of diverse abiotic stresses on plants ranging from model species to economically important crops. The newly identified and characterized mechanisms and genetics associated with plant adaptability to abiotic stress will provide novel insights into the physiological and molecular alterations of plants under abiotic stresses. It will assist in understanding plants’ behavior adapting to the environmental change and perspective agricultural practice including crop breeding and field management, and eventually help maintain the food security, safety, and sustainability. In addition, increasing evidence shows that the recent advancements and developments of plant biotechnologies and application of big data to the area of plant science promote the understanding of the physiological and molecular effects of diverse abiotic stresses on plants. Hence, the investigations integrated by multidisciplinary approaches are strongly encouraged, including but not limited to: CRISPR/Cas-mediated gene editing, functional genomics, phenomics, and high-throughput phenotyping etc.
The present topic aims at clarifying the effects of various abiotic stresses on crop important agronomic traits, and elucidating the underlying mechanisms, especially by the application of novel (bio-)technologies and data-driven analytics.
This research topic calls for original research and review articles, focusing on the characterization of novel factors and signaling networks that interact with abiotic stresses in plants, as well as new factors and mechanisms of action that cause changes in important agronomic traits. For example, what is the possible pathway by which changes in light quality lead to changes in fruit color or intrinsic quality? Changes in air temperature or soil moisture cause premature senescence of trees, such as early leaf yellowing (shedding or not shedding), early flowering, and falling fruit. What might be the respective mechanisms? Submissions on the following topics are welcome, but not limited to:
• Physiological and molecular mechanisms by which abiotic stress factors affect plant growth and development, fruit quality, and yield.
• Novel factors and signaling networks for plant-abiotic stress interactions.
• New functions of effector genes or proteins of plant agronomic traits under certain abiotic stress conditions.
• Novel molecular tools for studying plant-abiotic stress interactions.
• New methods, new approaches, and mechanisms for improving plant abiotic stress tolerance.
Descriptive studies that report responses to abiotic stress treatments without contributing to the mechanistic, or genetic, understanding of the responses observed will not be considered for peer review.
