Progress of the SUPERMAN Epigenetic Mutation in Arabidopsis
拟南芥SUPERMAN基因表观突变的研究进展 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 C pG and C PX PG is controlled by METHYLTRANSFERASE1(MET1) and CHROMOMETHYLASE3 (CMT3) which is regulated by KRYPTONITE gene,respectively.
