Plants will be stressed by various abiotic factors during the growth and development process, among which temperature has a particularly serious impact on plant growth and development. As global climate change continues to cause extreme weather patterns, understanding the mechanisms through which plants respond to high temperatures has become a crucial area of research. High-temperature stress leads to the closure of plant stomata, decreased photosynthesis, changes in internal water relations, dry matter production, respiration, mineral metabolism, hormone balance, antioxidant systems, and other important signals and metabolic processes, seriously affecting plant growth and reproduction, resulting in reduced crop yields. Therefore, the molecular mechanism of plant high-temperature stress response has attracted more and more attention.

Long noncoding RNA (lncRNA) is a kind of long non-coding RNA with a length greater than 200 nt, which is an integral part of the non-coding genome. Based on genomic location and position relative to adjacent or overlapping protein-coding genes, lncRNAs can be classified into intronic lncRNAs, intergenic lncRNAs (lincRNAs), natural antisense lncRNAs, and sense lncRNAs. lncRNAs can be further classified based on associated genomic features, such as promoters, enhancers, and transposable elements. In recent years, long non-coding RNAs (lncRNAs) have emerged as essential players in modulating gene expression and coordinating plant responses to high-temperature stress.

Mechanisms of Plant lncRNA Response to High-Temperature Stress

• Accumulation of osmoregulatory substances

We provide analysis services for plant lncRNA in regulating genes involved in synthesizing and accumulating osmoregulatory substances such as proline, soluble sugars, and heat shock proteins. The main strategy used by plants to mitigate high-temperature stress is the accumulation of osmoregulatory substances. These substances help maintain cellular osmotic potential and prevent water loss through transpiration.

• Calcium ion regulation

We offer analysis of plant lncRNA in calcium ion regulation. Plant lncRNAs are involved in regulating calcium ion homeostasis by modulating the expression of calcium-related genes. In response to high-temperature stress, the intracellular concentration of calcium ions increases, activating signaling pathways that initiate protective responses.

• Cell membrane protection

We help analyze the role of plant lncRNAs in maintaining the integrity of cell membranes by regulating the expression of genes involved in lipid metabolism and membrane stability. By promoting the synthesis of lipids and regulating lipid composition, lncRNAs contribute to the protection of cell membranes from high-temperature damage.

• Stomatal regulation

We know the crucial role of stomata in regulating the exchange of gases and water vapor between plants and the environment. Therefore, our services involve plant lncRNAs in regulating stomatal movements by modulating the expression of genes involved in stomatal development and functioning.
