摘要
microRNA(miRNA)在植物生长发育和环境胁迫中发挥着重要的作用.本研究基于49个水稻小RNA测序数据,系统分析了已知miRNA的表达,并鉴定到了新的水稻miRNA.研究发现,miRBase上注释的水稻miRNA中,只有39%具有可检测的表达.此外,对水稻降解组数据的分析鉴定到一些新的miRNA靶基因,包括2个新的miR444靶基因,它们分别编码WD40蛋白和热休克因子型DNA结合蛋白.
microRNA （miRNA） play essential roles in plant development and environmental adaption. Here, based on 49 Oryza sativa （rice） small RNA-seq datasets, It was systematically analyzed the expressions of known miRNAs and identified novel miRNAs in rice. It was showed that only 39% annotated miRNAs on miRBase had detectable expressions. Additionally, analysis of rice degradome datasets identified a few new miRNA targets including two miR444 targets that encode a WD40 protein and a HSF （heat shock factor）-type DNA-binding protein.
