[Progress of the SUPERMAN epigenetic mutation in Arabidopsis].
The SUPERMAN gene in Arabidopsis has its epigenetic mutants (the clark kent alleles,clk). The phenotype of clk and its genotype and methylated patterns and the epi-mutation mechanisms of SUPERMAN were summarized in the review. Heritable but unstable sup epi-alleles are associated with nearly identical patterns of excess cytosine methylation within the SUP gene and a decreased level of SUP RNA. The methylation of cytosine at CpG and CPXPG is controlled by METHYLTRANSFERASE1(MET1) and CHROMOMETHYLASE3 (CMT3) which is regulated by KRYPTONITE gene, respectively.
