摘要: 利用生物信息学方法,根据已知植物miRNA(microRNA)的各种特征,设计miRNA预测程序-MirFinder,从葡萄全基因组范围中预测出146条miRNA,然后利用葡萄中已知的miRNA对这146条miRNA进行同源检索,发现其中98条与已知的miRNA完全相同,另外48个为新发现的miRNA。这些新发现的miRNA基因属于21家族,其中8个家族之前未在葡萄中报道过,为葡萄中新发现的miRNA家族,共有20个miRNA。根据植物miRNA和其靶基因间存在较高的序列互补性,预测新miRNA家族的靶基因,结果表明其中6个miRNA家族存在靶基因。

Abstract: microRNAs ( miRNAs) represent a new family of non-protein-coding small RNAs ( 20- 25nt ) that functionby degrading targeted mRNAs or repressing mRNA translation. Here we developed a program-MirFinder for predictionof grape miRNAs.The characteristic features of known plant miRNAs were used as criteria to search for miRNAs. Aftersearching the grape genome, MirFinder ident ified 146 miRNAs, of which 98 miRNAs were the same as known miRNAsand 48 are new ident ified miRNAs.The 48 miRNAs were classified into 21 families, of which 8 families are newly identified in grape. A total of 15 potential targets were identified for 6 of the 8 new miRNA families based on the fact that miRNAs exhibit perfect or nearly perfect complementarity with their target sequences
