| contents | The methylome of clonal seagrass shoots shows age-associated variation and differentiation of roots from other tissues. Nilsen, Anne M L Hoarau, Galice Smolina, Irina Coyer, James A Boström, Christoffer Kopp, Martina E L Jueterbock, Alexander DNA Methylation Plant Roots Plant Leaves Zosteraceae Plant Shoots Epigenesis, Genetic Epigenome Rhizome Cell Differentiation Factors influencing variance of DNA methylation in vegetatively reproducing plants, both terrestrial plants and aquatic seagrasses, is just beginning to be understood. Improving our knowledge of these mechanisms will increase understanding of transgenerational epigenetics in plant clones, of the relationship between DNA methylation and seagrass development, and of the drivers of epigenetic variation, which may underly acclimation in clonally reproducing plants. Here, we sampled leaves, rhizomes and roots of three physically and spatially separated ramet sections from a clonally propagated field of the seagrass Zostera marina. Using reduced methylome sequencing, we studied variations in the methylome of seagrass Zostera marina between the sampled tissue types and across age groups. Our analysis of ramets of different ages showed variations in methylation between older and younger samples in both specific methylation patterns and global methylation levels. Our analysis of tissue types showed a marked differentiation of the roots from the rhizomes and leaves, which showed more similar methylation patterns. These findings are in agreement with the strong connection of DNA methylation and plant development and tissue differentiation. We also suggest an effect of differential environmental exposures on the methylome of the younger versus the older ramets due to the forming of molecular stress memories. |
