Heritable phenotypic variation due to partial maintenance of organ-specific epigenetic marks during asexual reproduction ($) (PNAS)
Clonal propagation is widely used by humans to maintain and propagate desirable phenotypic traits in plants. Despite a restricted genetic variety, phenotypical difference, known a somaclonal variation, arises sometimes between parents and the clonally propagated progeny. Some of this variability is attributed to epigenetic variation, but the origins and underlying molecular principles remain unclear. By […]
