Artificial microRNAs (amiRNAs) have been shown to facilitate efficient gene silencing with high specificity to the intended target gene(s). For the plant breeder, gene silencing by artificial miRNAs will certainly accelerate gene discovery, because it allows targeting of all genes in a mapping interval, independent of the genetic background. In addition, beneficial knockout phenotypes can easily be transferred between varieties and across incompatibility barriers. This chapter describes the generation and application of amiRNAs as a gene silencing tool in rice.
人工微小RNA(amiRNA)已被证明能促进有效的基因沉默,且对目标基因具有高度特异性。对于植物育种者而言,通过人工miRNA进行基因沉默无疑将加速基因发现,因为它能够针对定位区间内的所有基因进行靶向作用,而不受遗传背景的影响。此外,有益的基因敲除表型能够轻易地在不同品种间转移,并跨越不亲和障碍。本章介绍了amiRNA作为水稻基因沉默工具的产生及应用。
