Somaclonal variation is manifested as cytological abnormalities, frequent qualitative and
quantitative phenotypic mutation, sequence change, and gene activation and silencing …

▪ Abstract Methylation of cytosine residues in DNA provides a mechanism of gene control.
There are two classes of methyltransferase in Arabidopsis; one has a carboxy-terminal …

The establishment of DNA methylation patterns requires de novo methylation that occurs
predominantly during early development and gametogenesis in mice. Here we demonstrate …

This book comprehensively covers epigenetic mechanisms, including DNA methylation,
paramutation, imprinting, X-inactivation, repeated genes, gene silencing, nuclear …

It has been a controversial issue as to how many DNA cytosine methyltransferase
mammalian cells have and whether de novo methylation and maintenance methylation …

DNA methylation patterns were evaluated during preimplantation mouse development by
analyzing the binding of monoclonal antibody to 5-methylcytosine (5-MeC) on metaphase …

Recent research has demonstrated that DNA methylation plays an integral role in regulating
the timing of flowering and in endosperm development. The identification of key genes …

Comparative studies have provided the basis for some of the most important discoveries in
biology. The study of differences, whether at the level of gene alleles or living kingdoms, has …

Some biological regulatory systems must “remember” a state for long periods of time. A
simple type of system that can accomplish this task is one in which two regulatory elements …

Recent studies showing a correlation between the levels of DNA (cytosine-5-)-
methyltransferase (DNA MTase) enzyme activity and tumorigenicity have implicated this …
