Deciphering the Drought and Thermo -tolerance Mechanisms in Plants: The Road Ahead of Future Research

Contributions are invited for the upcoming Special Issue of Plant Cell Reports dedicated to drought and thermo-tolerance mechanisms in plants. This Special Issue will provide a timely appreciation of recent and future developments in this field, based on original contributions, reviews and opinion papers highlighting the most significant lines of research that are likely to give rise to exciting new achievements in both our understanding of the related biology and their applications in the agronomic context. Submissions to this Special Issue are accepted until February 28, 2021.

Rising global mean temperature due to climate change is likely to aggravate the detrimental effects of heat stress (HS) and drought stress (DS) on plants. Heat and drought stress together become more lethal and profoundly suppress plant growth and development by adversely affecting key metabolic processes including photosynthesis, primary and secondary metabolism, and lipid and hormonal signaling. Prolonged exposure to high-intensity heatwaves and drought periods can persuade cellular oxidative damage due to generation of reactive oxygen and nitrogen species (ROS/RNS).

In response to stress, plants have evolved some long-term adaptations and short-term stress avoidance and acclimation mechanisms. These mechanisms include changes in root and shoot systems architectures, expression of heat shock proteins (HSPs), and heat shock factors (HSFs), and plant growth regulators, osmo-protectants, free-radical scavengers, ion transporters and factors involved in signaling cascades and transcriptional control which collectively are essential to counteract HS and DS.

The latest studies have recognized several adaptive responses to both stresses at morphological, physiological, biochemical, cellular, metabolic, and molecular levels. But how these defense mechanisms operate in harmony are a long away from being completely comprehended. Thus, the present special issue will provide a better understanding on the underlying morphological, physiological, biochemical and molecular mechanisms and their interactive action in plant adaptation and resistance to HS and DS. Subsequently, following key aspects will be covered in this special issue:

  • Changes in root and shoot systems architectures and adaptation to HS and DS
  • Involvement of HSPs, HSFs, and precise metabolic proteins in HS and DS -tolerance
  • Emerging role of microRNA in regulation of plants adaptation under HS and DS
  • Deep sequencing technologies (next generation; NGS) and genomic approaches to determine the multiplicity of HS/DS responses
  • Interaction of HSPs with signaling molecules in HS tolerance mechanism
  • Carbon dioxide (CO2) induced protection mechanism under HS or DS
  • Regulation of HS and DS -tolerance mechanisms by phytohormones, and primary and secondary metabolites
  • Use of chemical compounds in alleviating HS and DS 
  • Impact of HS and DS on plant growth, flowering, and seed/fruit yield
  • Impact on agricultural practices
  • Impact on agronomic performance including economic and regulatory aspects
  • And other related topics
