We reviewed the mechanisms of epigenetic regulation of vernalization genes of plants, controlling the transition to the generative stage, depending on the low temperature.
Based on the example of FLC-gene of Arabidopsis, the involvement of the PR2 repression complex and non-coding RNAs in these mechanisms were shown.
On the basis of both own and other data, the authors suggest a similar mechanism of regulation of Vrn-1 gene of cereals.
Key words: vernalization gene, wheat, epigenetic regulation, heading time
