OsJMJ703, a Histone H3K4 Demethylase, Controls Transposon Activity in Rice

ABSTRACT: Retrotransposons are classified into long terminal repeat (LTR) or non-LTR retrotransoposons, and both types can mobilize in a “copy and paste” manner. Rice genome contains >40% of repetitive sequences or transposable elements (TEs) that scattered throughout the genome. TE activities are tightly regulated by distinct epigenetic mechanisms. Histone lysine methylation is catalyzed by SET domain group (SDG) protein and reversed by a family of Jumonji C (JmjC) domain-containing proteins. In rice, DNA methylation and histone methylation have been implicated in controlling copia-like LTR retrotransposon Tos17 activities. Whether any TEs are controlled by histone demethylase remains to be elusive. Here, we show that JMJ703 is a histone H3K4 specific demethylase in rice. Impaired JMJ703 disrupted
