At the present, the functional genomics (as a basis of economic valuable signs studying the regulation of genes expression) has been actively developed in plant breeding research. In recent years, it has been shown, that various RNAs, including microRNAs, play an important role in genes regulation by activating or inhibiting the expression of plant growth and development genes, genes to environmental response. Then, quite recently, it was shown that there are a new class of RNA molecules � circular RNA, with size from 100 up to 4000 nucleotids, which are formed from microRNA as a result of back-splicing. They have regulatory functions and interact with macroRNA, as well as with matixRNA, affecting the level of genes expression of growth, development, and response to abiotic and biotic stresses. In this mini-review, an analysis of recent data on the role of circular RNA in the plants is presented. It is also shown specificity their of formation depending on the type of plant tissue of intron, exon, exon-intron origin, the interaction between circular RNA, microRNA, and matrix RNA with indirect influence the genes work, as well as their role in regulating the response to abiotic and biotic stresses. The article has been presented data for searching of plant circular RNA, a bioinformative prediction method, a specific circular RNA for rice, arabidopsis, tea, tomato, cucumber, grapes, soy, peanuts, poncirus, as well as data of their regulatory role in response to stress factors of environment.
