Peculiarities of Transcriptional Activity of Long Non-Coding RNAs (<i>COOLAIR, COLDAIR</i>, and <i>COLDWRAP</i>) during the Vernalization of the Plant <i>Arabidopsis thaliana</i> of Northern Natural Populations

Abstract

Peculiarities of the lncRNA expression – COOLAIR, COLDAIR, and COLDWRAP, which perform an important function in the vernalization-mediated epigenetic mechanism of the transition to flowering in A. thaliana plants of northern natural populations (Karelia), were revealed. The results obtained are partly differ from the data of other authors performing studies on pure lines and other ecotypes of this species. It is suggested that the genetic and epigenetic mechanisms involved in the process of vernalization and control of flowering times may differ in plant populations from different geographic regions.
