Abstract:

Low temperature is a major limiting factor for plant growth and production, affecting planting range, crop yield, quality, and even causing death. To cope with low-temperature stress, plants have evolved complex defense mechanisms. lncRNAs are a group of transcripts generated by genomic transcription and found in both the cytoplasm and nucleus of cells. In recent years, researches have shown that lncRNAs respond to low-temperature stress in plants through mechanisms such as polyadenylation, synergistic effects with specific proteases, and competitive binding with miRNAs. This review provides a summary of the definition, origin, and classification of lncRNAs, with a focus on their roles in low-temperature stress response in the model plant Arabidopsis thaliana and agro-economic crops. The findings presented in this review will serve as a valuable reference for those studying plant low-temperature tolerance mechanisms and molecular breeding for cold-tolerance.

Key words: cold stress, lncRNA, miRNA, transcription factors
