How volatile isoprenoids improve plant thermotolerance.

Area of Science:

• Plant Physiology
• Biochemistry
• Environmental Science

Background:

• Volatile isoprenoids, including isoprene and monoterpenes, are crucial for plant thermotolerance.
• They mitigate heat stress by lowering reactive oxygen species (ROS) and preserving cellular functions.
• Emerging evidence highlights their role as signaling molecules in heat response pathways.

Purpose of the Study:

• To review current knowledge on isoprenoid-mediated plant thermotolerance.
• To elucidate the underlying mechanisms and signaling pathways involved.
• To explore the potential application of isoprenoids in enhancing crop heat tolerance.

Main Methods:

• Literature review of existing studies on isoprenoids and plant thermotolerance.
• Analysis of recent findings on signaling pathways, including Ca2+-mediated mechanisms.
• Synthesis of information on gene expression and physiological responses.

Main Results:

• Isoprenoids protect plants by maintaining photosynthesis, preserving chloroplast integrity, and inducing heat shock proteins.
• They act as signaling molecules, influencing gene expression via calcium-dependent pathways.
• Understanding these mechanisms is key to developing strategies for heat stress management.

Conclusions:

• Isoprenoids play a multifaceted role in plant thermotolerance, acting both protectively and as signaling agents.
• Further research into isoprenoid pathways can lead to novel approaches for improving crop resilience.
• Harnessing isoprenoid functions offers a promising strategy to combat the impacts of global warming on agriculture.
