Abstract：
MicroRNAs (miRNA) are a class of endogenous, non-coding, small RNAs with about 22 nucleotides (nt), that are widespread in plants and are involved in various biological processes, such as development, flowering phase transition, hormone signal transduction, and stress response. The transcriptional regulation of miRNAs is an important process of miRNA gene regulation, and it is essential for miRNA biosynthesis and function. Like mRNAs, miRNAs are transcribed by RNA polymerase II, and these transcription processes are regulated by various transcription factors and other proteins. Consequently, the upstream genes regulating miRNA transcription, their specific expression, and the regulating mechanism were reviewed to provide more information for further research on the miRNA regulatory mechanism and help to further understand the regulatory networks of plant miRNAs.
摘要：
MicroRNAs(miRNA)是一类内源性的,非编码，具有约22个核苷酸（nt）的小RNA，广泛存在于植物中并参与各种生物过程，如发展,开花相变，激素信号转导，和应激反应。miRNA的转录调控是miRNA基因调控的重要过程,它对于miRNA的生物合成和功能至关重要。像mRNA一样，miRNA通过RNA聚合酶II转录,这些转录过程受各种转录因子和其他蛋白质的调节。因此,调节miRNA转录的上游基因，他们的具体表达，并对其调控机制进行综述,为进一步研究miRNA调控机制提供更多信息,有助于进一步了解植物miRNA的调控网络。
