Somatic mutation and evolution in plants

WebJun 19, 2013 · Introduction. Plants violate the Weismann's doctrine of the separation of germ line and soma (Weismann, 1893).Although in theory, this means that mutations can be passed from the soma to gametes, it is unclear how often mutations occur in somatic tissue during plant development, and whether and by how much intra-organismal selection filters … WebA somatic mutation is a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells; that is, any mutation that occurs in a cell …
