Buglia, G.L., Predazzi, V., & Ferraro, M. 1999 Cytosine methylation is not involved in the heterochromatization of the paternal genome of mealybug Planococcus citri.. Chromosome Research 7(1): 71-73.
Keywords:
Notes: The characteristics which allow P. citri to be studied easily as a model system for the phenomena of heterochromatization and genomic imprinting are identified. The possible presence of cytosine methylation is investigated, both at DNA and chromosome levels.
