摘要
Gene silencing can occur either at the transcriptional level or post-transcriptional level or both. Many instances of sequence-specific silencing requires small RNAs that can be divided into two major classes： microRNAs （miRNAs） and short-interfering RNAs （siRNAs）. miRNAs function in post-transcriptional gene silencing by guiding mRNA degradation or translational repression, Endogenous siRNAs are more diverse in plants than in animals and can direct post-transcriptional gene silencing through mRNA degradation or transcriptional gene silencing by trigger- ing DNA methylation and histone modifications. This review discusses recent advances in the field of small RNA- guided gene silencing in plants including rice.
