Abstract

microRNAs are small noncoding RNA gene products about 20-24nt long that are processed by Dicer from precursors with a characteristic hairpin secondary structure. As miRNAs affect the morphology of plants and animals by the posttranscriptional regulation of genes involved in critical developmental events, it has been proposed that precise regulation of miRNAs activity during various stages of growth and in specific cell types is of central importance for normal plant development. In our work we focus on the plant miRNAs and predict the miRNA targets, affected proteins by miRNA and miRNA homologs of Glycine max. Our analyses were based on sequence complementarities between miRNAs and mRNAs. As a result, we predicted 573 targets for 44 mature miRNAs sequences among 69 mature miRNAs sequences were published in database. Study of affected proteins revealed that for very less number of miRNAs, protein products are known and they mostly involved in diverse physiological process like as element of photosynthesis system. Homology analyses for miRNAs suggested that 22 miRNAs of Glycine max show 418 miRNA homologs for different plant species.
