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

Background: Arabidopsis mutations causing genome-wide hypomethylation are viable but
display a number of specific developmental abnormalities, including some that resemble …

▪ 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 …

Plants with low levels of DNA methylation show a range of developmental abnormalities
including homeotic transformation of floral organs. Two independent DNA …

Three DNA hypomethylation mutants of the flowering plant Arabidopsis thaliana were
isolated by screening mutagenized populations for plants containing centromeric repetitive …

Methylation of plant DNA occurs at cytosines in any sequence context, and as the
Arabidopsis methyltransferase, METI, preferentially methylates cytosines in CG …

The function of DNA methylation in higher plants was investigated by expression of a
complementary DNA encoding a cytosine methyltransferase (MET1) from Arabidopsis …

Cytosine bases are extensively methylated in the DNA of plant genomes. DNA methylation
has been implicated in the silencing of transposable elements and genes, and loss of …

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 …

We have recently isolated two Arabidopsis thaliana DNA hypomethylation mutations,
identifying the DDM1 locus, that cause a 70% reduction in genomic 5-methylcytosine levels …
