About this Research Topic
Drought and water deficit stress are negatively impacting arable lands and threatening crop production all over the world. These issues are likely to worsen with the anticipated climate change. In addition, drought may co-occur in some environments with heat stress or salinity. Plants have developed a variety of physiological and biochemical responses at cellular and organism levels, making it a more complex phenomenon. Researchers have been trying to understand and dissect the mechanisms of plant tolerance and resistance to drought stress by using various approaches. It is becoming obvious that solutions to these problems will not come from a single strategy but rather from the combination of different approaches: physiology, molecular biology, breeding, big data, and agronomy.
This Research Topic aims to unravel recent scientific advances, strategies, and techniques that could help to improve plant responses to drought and water deficit stress to boost crop production.
We welcome researchers to submit their findings in the form of Reviews, Original Research, Methods, Brief Research Report, Perspective, and Opinion articles. The key aspects of this collection include, but are not limited to:
• Fundamental description of the variables resulting in yield limitation under drought
• Recent advances in elucidating stress-response mechanisms
• Deciphering physiological and biochemical pathways responsible for stress tolerance mechanisms in plants (drought/salinity/heat)
• Improving crop production using multi-omics techniques
• Realistic options for increasing yield and innovative field crop management
• Identifying target genes to improve tolerance mechanisms in crop plants using recent gene-editing systems
• Recent agronomic approaches to mitigate drought stresses
• Conceptual and mathematical modeling for improved water management in cropping systems
Keywords: crop, drought, tolerance, agronomy
