Activity of MuDR(p5) and MuDR(p4) in a family segregating for these elements and Muk.

agenotype of parents with respect to MuDR(p5) (P5), MuDR(p4) (P4) and Mu killer (Muk). Each parent plant was genotyped and then crossed to an a1-mum2 tester and the resulting frequencies of heavy/medium (hm), weakly spotted (weak) and pale kernels were tabulated.bparent plant numbers correspond to lane numbers in Figure 3.cmethylation status of Mu1 in the parents of the families tabulated here, as determined by the blot in Figure 3C.dparent plants had unmethylated Mu1 and MuDR elements.eparent plants had methylated Mu1 and MuDR elements.
