Here, we have characterized a maize chromatin protein, ZmMBD101, which is involved in the regulation of Mutator transposon genes in maize. ZmMBD101 is localized to the nucleus and binds both methylated and unmethylated DNA. mbd101 RNAi maize plants have Mutator elements chromatin in a less repressive state, in particular under UV‐B conditions. In addition, we present evidence for a biological role of a monocot MBD protein.
