Lifetime genealogical divergence within plants leads to epigenetic mosaicism in the shrub Lavandula latifolia (Lamiaceae)

What is it about?

Different parts of the same plant can be epigenetically different, but such extant 'epigenetic mosaicism' can either reflect recent, ephemeral epigenetic modifications experienced independently by different plant parts or the stable, cumulative outcome of a lifetime process of internal epigenetic divergence. Phylogenetic reconstruction methods applied to plant branching architectures and epigenetic data of modules (tips) disclosed that epigenetic mosaicism in lavender plants was the consequence of changes taking place throughout the life of plants.
