This review focuses on the biological role of one class of plant small RNAs, ~22-nt microRNAs (miRNAs). The majority of plant miRNA targets are genes encoding the effector factors of cell signaling pathways. The regulation of their expression is necessary for both ontogenesis and rapid response of plants to biotic and abiotic stress factors. We also summarized current views on the biogenesis and evolution of plant miRNAs as well as the techniques used for their investigation.
这篇综述聚焦于一类植物小 RNA，即 22nt 左右的 microRNAs（miRNAs）的生物学作用。大多数植物 miRNA 的靶标是编码细胞信号通路效应因子的基因。它们表达的调控对于植物的个体发生和对生物及非生物胁迫因子的快速响应都是必需的。我们还总结了目前对植物 miRNA 的生物发生和进化以及用于研究它们的技术的看法。
