Grapevine adaptation to cold and heat stress

Area of Science:

• Plant Science
• Agriculture
• Genetics

Background:

• Temperature significantly impacts plant growth, development, and distribution.
• Grapevine (Vitis spp.) must tolerate temperature fluctuations, but cultivated Vitis vinifera L. is sensitive to extreme cold and heat.
• Wild grapevine germplasms exhibit superior cold and heat tolerance.

Purpose of the Study:

• To review current research on grapevine cold and heat tolerance mechanisms.
• To identify existing knowledge gaps in grapevine stress resistance.
• To suggest future research directions for enhancing grapevine resilience.

Main Methods:

• Literature review of physiological, metabolic, and molecular studies on grapevine temperature tolerance.
• Analysis of research progress in understanding grapevine resistance mechanisms.
• Identification of key areas for further investigation.

Main Results:

• Significant advancements have been made in understanding grapevine resistance.
• Research has focused on physiological, metabolic, and molecular regulatory processes.
• Understanding of the precise mechanisms underlying grapevine cold and heat resistance remains incomplete.

Conclusions:

• Further research is needed to fully elucidate grapevine cold and heat resistance mechanisms.
• Investigating wild germplasms can provide insights into enhancing cultivated grapevine tolerance.
• Addressing knowledge gaps is essential for improving grapevine adaptation to climate change.
