Abstract

Plant growth and productivity are greatly impacted by environmental stresses. Therefore, plants have evolved mechanisms which allow them to adapt to abiotic stresses through alterations in gene expression and metabolism. In recent years, studies have investigated the role of long noncoding RNA (lncRNA) in regulating gene expression in plants and characterized their involvement in various biological functions through their regulation of DNA methylation, DNA structural modifications, histone modifications, and RNA-RNA interactions. Genome-wide transcriptome analyses have identified various types of noncoding RNAs (ncRNAs) that respond to abiotic stress. These ncRNAs are in addition to the well-known housekeeping ncRNAs, such as rRNAs, tRNAs, snoRNAs, and snRNAs. In this review, recent research pertaining to the role of lncRNAs in the response of plants to abiotic stress is summarized and discussed.

摘要

植物生长和生产力受到环境胁迫的极大影响。因此，植物进化出了一些机制，使其能够通过基因表达和代谢的改变来适应非生物胁迫。近年来，研究调查了长链非编码RNA（lncRNA）在调节植物基因表达中的作用，并通过其对DNA甲基化、DNA结构修饰、组蛋白修饰和RNA-RNA相互作用的调控，阐明了它们在各种生物学功能中的作用。全基因组转录组分析已经鉴定出了多种响应非生物胁迫的非编码RNA（ncRNA）。这些ncRNA除了包括众所周知的管家ncRNA，如rRNA、tRNA、snoRNA和snRNA。在这篇综述中，总结并讨论了lncRNA在植物对非生物胁迫响应中作用的最新研究。
