摘要: 长链非编码RNA (long non-coding RNA, lncRNA)广泛存在于真核生物基因组中, 在维持生物体正常生命活动中发挥重要作用。近年来, 通过高通量测序和生物信息学分析在植物中发掘到大量的lncRNA。已有研究证实lncRNA在调控植物生长发育和逆境响应中发挥重要作用。由于基因组复杂且遗传操作过程繁琐, lncRNA在玉米(Zea mays)中的研究远落后于拟南芥(Arabidopsis thaliana)和水稻(Oryza sativa)。玉米作为我国主要粮食作物, 对于保障国家粮食安全至关重要。玉米还是遗传学与基因组学领域重要的模式植物。了解lncRNA在玉米中的研究进展有助于理解lncRNA的生物学功能。挖掘并解析lncRNA参与玉米生长发育和逆境响应的分子调控网络, 可为玉米遗传改良提供新的分子靶点。该文总结了lncRNA的来源、分类和作用机制, 并讨论了玉米中lncRNA的发掘及其在调控生长发育和逆境响应中的生物学功能, 最后展望了lncRNA在玉米中的研究方向。

Abstract: Long non-coding RNAs (lncRNAs) are widely present in the genomes of eukaryotic organisms and play crucial roles in maintaining the biological activities of living organisms. In recent years, a large number of lncRNAs have been discovered in plants through high-throughput sequencing and bioinformatics analysis. LncRNAs play important roles in regulating plant growth, development, and stress responses. Due to the complexity of the genome and the low efficient of genetic transformation, the functional analysis of lncRNA in maize is relatively lagging behind comparing with that in Arabidopsis and rice. Maize is a major staple crop in China, playing a critical role in ensuring national food security. It’s also an important model plant in the fields of genetics and genomics. Understanding the research progress of lncRNA in maize is highly beneficial for comprehending the biological functions of lncRNA. Mining and analyzing the molecular regulatory network of lncRNAs involved in maize development and stress response can provide potential molecular targets for future genetic improvement of maize. In this review, we summarized the sources, classification, and action mechanisms of lncRNAs, and reviewed the discovery of lncRNAs in maize and their biological functions in regulating growth, development, and stress responses. We also discussed the current research status and provided an outlook on future researches of lncRNAs in maize.
