Comparison of Methylation of the Male- and Female-Derived wx-m9Ds-cy Allele in Endosperm and Sporophyte

  • Drew Schwartz
Part of the Basic Life Sciences book series (BLSC, volume 47)


Differential cytosine methylation in the gametes and maintenance methylation are proposed to account for the differential functioning of male- and female-derived genes, such as R, in the endosperm. Experiments with the wx-m9Ds-cy transposable element mutant, with which it is possible to quantitate cytosine methylation of a particular PvuII site, provided evidence for this model.
