Features of the interaction of miRNAs with genes of the rice MYB family under stress

Abstract

Data on the involvement of miRNA in the plant response to stress factors are considered. The MYB family of transcription factors plays a great role in the plant development, metabolism and responses to biotic and abiotic stress. The free energy of miRNA binding, the value of free energy of interaction, the position and schemes of potential binding sites were calculated using the MirTarget program. To identify miRNAs whose targets are genes in the MYB family, a search for binding sites of 738 miRNAs in mRNAs of 124 MYB family genes of Oryza sativa was performed. 16 genes were identified as targets for 11 miRNAs. The results show that miRNA can regulate the expression of most MYB genes and thus affect productivity and sustainability.
