Inheritance of vernalization memory at FLOWERING LOCUS C during plant regeneration.

ABSTRACT: Specific gene states can be transmitted to subsequent cell generations through mitosis involving particular chromatin (epigenetic) states. During reproduction of plants and animals, however, most epigenetic states are reset to allow development to start anew. Flowering is one of the critical developmental steps by which plants acquire their reproductive capacity. This phase transition is controlled by environmental signals and autonomous regulation. The FLOWERING LOCUS C (FLC) gene is a flowering repressor that is epigenetically silenced after long-term exposure to cold, ensuring flowering in the spring season. In Arabidopsis thaliana, epigenetically silenced FLC expression is reset during sexual reproduction. Plants have a remarkable potential to regenerate from somatic cells. However, li
