NEW APPROACH TO SOLVING PROBLEM OF LEAF FACIAL STRUCTURE BY MEANS OF MOLECULAR-GENETIC METHOD Abaxial-adaxial symmetry during leaf development of flowering plants is known to be controlled by microRNAs (miRNAs).These RNAs influence accumulation of mRNAs encoding transcription factors required for specific modulation of gene expression in tissues of developing leaf. Sequential activity of miR390 and TAS3 tasiARF RNAs (21 nucleotides in length) controls synthesis of transcription factors ARF3 and ARF4 in Arabidopsis thaliana. We have studied the presence of tasiARF RNA genes in the representatives of genus Senecio having either unifacial or true bifacial leaves. It was found that both types of species encode RNA precursors principally similar to those found in Arabidopsis. The data obtained will be used for further studies of expression regulation of Senecio TASS-like genes and understanding the potential contribution of these RNAs in development of plant organ abaxial-adaxial symmetry.
