Abstract
MicroRNAs (miRNAs) are tiny, non-protein coding and negative regulatory RNAs approximately 21 nucleotides in length. The comparative genomic methodology due to their conserved nature is a reasonable approach for the novel miRNAs discovery. In this research, total 25 novel miRNAs from 18 families (ras-miR-156, 160, 162, 163, 164, 167, 168, 319, 399, 408, 413, 414, 841, 1310, 2936, 5030 and 5661) are identified in an important vegetable radish (Raphanus sativus L.). The 25 miRNA precursor sequences showed secondary structures with the mature miRNAs in the stem region. Total 42 putative targets are also identified for the novel 25 radish miRNAs. These findings suggest that more thorough understanding of the function of such miRNAs will help to unravel the mysteries role in plant biology.
