Abstract
In plants, multiple layers of epigenetic regulators are required for heterochromatin-associated silencing, including many repetitive sequences and transposable elements (Regal and Mathieu, Bio- chim Biophys Acta., 2011). However, the control mechanism of tissue specific heterochromatic silencing is still unknown. Here, we report the new Arabidopsis gene affecting hetero- chromatin-associated silencing, KUMONOSU (KUN). We iso- lated kun mutant from the screening affecting transgene silencing. In kun mutant, not only transgene, many endogenous repetitive sequence and transposable elements were activated. Moreover, the expression of specific genic regions was also affected and DNA methylation level of many target genes was slightly decreased in the mutant. Interestingly, release of silencing of the reporter transgene was observed specifically in vascular tissues of kun mutant, which may indicate possible tissue-specificity in the regulation of heterochromatin silencing.
