Summary
Histone modifications regulate plant responses to abiotic stresses like drought and extreme temperatures. This review synthesizes epigenetic mechanisms for stress tolerance and highlights research gaps in plateau crops.
Area of Science:
- Plant epigenetics and stress physiology.
- Molecular mechanisms of crop adaptation.
Background:
- Abiotic stresses significantly limit plant growth and crop yields globally.
- Histone modifications are crucial epigenetic regulators in plant stress adaptation.
- Understanding these modifications is key to enhancing crop resilience.
Purpose of the Study:
- To systematically review histone modifications and their roles in plant abiotic stress responses.
- To identify research gaps and propose future directions for plateau crop improvement.
- To provide a theoretical basis for epigenetic research in plant stress tolerance.
Main Methods:
- Literature review and synthesis of existing research on histone modifications in plants.
- Analysis of chromatin remodeling and gene expression under various abiotic stresses.
- Examination of crosstalk between histone modifications and key signaling pathways (ABA, CBF/DREB, ROS).
Main Results:
- Detailed summary of major histone modifications (acetylation, methylation) and their enzymes.
- Clarification of regulatory patterns under diverse stresses (temperature, drought, salinity, heavy metals).
- Discussion of transgenerational epigenetic inheritance and epigenetic editing applications.
Conclusions:
- Current research on histone modifications in plateau crops is fragmented, focusing on single stresses.
- Gaps exist in tissue-specific maps, multi-stress crosstalk, and field applications of epigenetic breeding.
- Future research should focus on multi-omics, plateau plant adaptation, and precise epigenetic breeding.

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.
02:45Responses 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.
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.
01:56Plant Hormones
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
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.
02:04Regulation of Transpiration by Stomata
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.
