Summary
High temperatures cause unpredictable rice sterility during flowering. This review covers research on temperature effects, damage mechanisms, and genetic tolerance to improve rice cultivation.
Area of Science:
- Agronomy
- Plant Physiology
- Molecular Biology
Context:
- High temperatures during rice anthesis lead to sterility, impacting crop yields unpredictably.
- Understanding the physiological and molecular basis of heat stress in rice is crucial for food security.
Purpose:
- To review current research on high temperature-induced rice sterility at anthesis.
- To consolidate knowledge on occurrence, damage mechanisms, genetic basis, and evaluation methods.
Summary:
- This paper synthesizes research on rice sterility triggered by high temperatures during anthesis, detailing influencing factors like temperature regimes and varietal differences.
- It covers damage mechanisms, evaluation techniques, genetic tolerance, and molecular aspects of anther dehiscence and pollen abortion.
Impact:
- Provides a comprehensive overview to guide future research and breeding strategies for heat-tolerant rice varieties.
- Informs agricultural practices to mitigate yield losses in rice cultivation under climate change scenarios.

02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
02:02Responses to Salt Stress
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
02:41Responses to Drought and Flooding
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
