摘要:

低温限制植物生长区域,决定种植范围;导致作物产量和品质下降,严重可能造成植株死亡。为了抵抗低温胁迫,植物进化出了复杂的防御机制。lncRNA是存在于细胞核和细胞质中、由体内基因组转录产生的一类转录本。近年来,已证实lncRNA可以通过多聚腺苷酸化、与某些蛋白酶协同作用、与miRNA竞争性结合等方式来响应植物低温胁迫。本文就lncRNA的定义、来源、分类以及低温条件下lncRNA在模式植物拟南芥和农经作物中的研究进展进行了总结,期望为植物耐低温机理研究及植物耐冷分子育种提供参考。

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
