The most common modification of DNA in plant cells is methylation of cytosine residues at
carbon 5. In contrast to mammalian cells in which 3–8% of cytosine residues are methylated …

▪ 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 …

DNA in plants is highly methylated, containing 5-methylcytosine (m 5 C) and N 6-
methyladenine (m 6 A); m 5 C is located mainly in symmetrical CG and CNG sequences but …

A relatively high degree of nuclear DNA (nDNA) methylation is a specific feature of plant
genomes. Targets for cytosine DNA methylation in plant genomes are CG, CHG and CHH (H …

Both replicative and postreplicative nuclear DNA (nDNA) methylation, with the formation of 5-
methylcytosine (mC) residues, occurs in plants. These two types of enzymatic DNA …

Cytosine DNA methylation is an epigenetic modification in eukaryotes that maintains
genome integrity and regulates gene expression. The DNA methylation patterns in plants …

Higher plant DNA is extensively methylated, but the two methylated sequences (CpG and
CpNpG) show different characteristics. Using sequence analysis techniques, we …

Arabidopsis plants transformed with an antisense construct of an Arabidopsis
methyltransferase cDNA (METI) have reduced cytosine methylation in CG dinucleotides …

The development of genetic tools to alter DNA methylation has led to a deeper
understanding of the importance of DNA modification in the life strategies of different …

Many studies have shown correlations between increased gene expression and decreased
DNA methylation (eg, Sullivan et aI., 1989; Piva et aI., 1989; Shinar et aI., 1989; Jahroudi et …
