| 摘要: |
| 为阐明microRNA(miRNA)及其靶基因调控植物根系生长发育的分子机制，依据PubMed、Web of Science和中国知网数据库，以“miRNA”、“植物”和“根系”为关键词，检索了1993—2021年发表的相关文献，进行整理和归纳，分析了miRNA及其靶基因对植物根系的调控机理。结果表明:1)根系生长发育是一个复杂且高度有序的生物学过程，众多的miRNA及其靶基因参与调控。2)miRNA通过互补配对的方式对靶基因进行转录切割或翻译抑制，在转录后水平调控根系生长发育相关基因的表达。3)miRNA介导的根系生长发育调控在主根生长、侧根形成、不定根发育、根系形态结构、维管束形态、植物激素诱导、生物和非生物胁迫响应等方面发挥着重要的调控作用。 |

| Abstract: |
| In order to clarify the molecular mechanism of microRNA(miRNA)and its target genes regulating plant root growth and development, related literature published in PubMed, Web of Science and CNKI from 1993 to 2021 with “miRNA”, “plant” and “root” as keywords were retrieved. Data obtained was sorted and summarized to analyzed regulation mechanism of miRNA and its target genes in plant root. The results showed that: 1)Many miRNAs and their target genes were involved in the regulation of root growth and development, which was a complex and highly ordered biological process. 2)MiRNA can cut target gene transcription or inhibits its translation through complementary pairing. It regulates the genes expression related to root growth and development at post-transcriptional level. 3)MiRNA-mediated regulation play an important regulatory effect in primary root growth, lateral root formation, adventitious root development, root structure, vascular bundle morphology, plant hormone induction, biotic and abiotic stress response on root growth and development. |
