Abstract
Epigenetic memory formed in the Norway spruce embryos permanently affect the timing of bud burst and bud set in the progenies, vitally important adaptive traits in this long-lived forest species. Epigenetic memory marks are established in response to the temperature conditions prevailing during embryogenesis; the epitype is fixed by the time the embryo is fully developed and is mitotically propagated throughout the tree’s life span. Somatic embryogenesis closely mimics the natural zygotic embryo formation and results in epigenetically different plants in a predictable temperature-dependent manner with respect to altered phenology. Using RNAseq transcriptome analysis of mRNA and noncodingRNA (ncRNA) changes were monitored in somatic embryos under different temperatures. We found distinct differences in mRNA and ncRNA transcriptomes between the genetically identical embryogenic tissues grown under the epitype-inducing temperatures suggesting temperature-dependent canalizing of gene expression during embryo formation, putatively based on chromatin modifications.
