About this Research Topic
Low-temperature stress is the primary abiotic stress that affects the growth and development of plants and their geographical distribution. This can lead to the solidification of membrane lipids and decrease of enzymatic reaction rate in plants in a relatively short time, or indirectly affect the imbalance of respiration and photosynthesis, accumulation of toxic substances, ATP depletion, cell solute leakage and wilting due to water loss. Low-temperature stress can be divided into chilling stress and freezing stress according to the damage caused to plants. Both chilling and freezing stress drastically threaten global food security and species diversity in the northern and frigid temperate zones. Once plants experience low-temperature stress, the regulation mechanism of gene expression is rapidly activated to cope with the adverse environment.
Over time, plants have formed a complex regulation mechanism of gene expression in response to low temperatures to survive and reproduce. In recent years, high-throughput sequencing technologies have developed rapidly, and multi-omics provide insights into the latest research platform in plants. Simultaneously, with the continuous application of molecular biology techniques, we are moving towards a better understanding of the molecular mechanism and biological breeding direction of plant tolerance to low-temperatures. However, we are far from knowing the exact mechanisms that confer resistance to cold conditions, and how plants respond to freezing stress.
We welcome submissions of original research papers, reviews, and methods, including (but not limited to) research on the following sub-themes:
- Mechanistic insights of plant responses to low-temperature stress
- The use of multi-omics approaches to provide insights into traits defining low-temperature tolerance for plant improvement
- The molecular basis of cold hardening in plants
- Understanding of cold hardening to enhance freezing tolerance in plants
- Functional validation of key genes and proteins involved in stress tolerance
- Genome editing/transgenic approaches to increase low-temperature tolerance
