Control of agricultural traits by hc-siRNA associated MITEs in rice

ABSTRACT: Transposable elements (TEs) and repetitive sequences comprise over 40% of rice genome. Different TEs are tightly regulated by distinct epigenetic mechanisms. For example, the activities of LTR retrotransposon Tos17 and non-LTR retrotransposon LINE element Karma are uniquely regulated by histone H3K9 methylation and histone H3K4 demethylation, respectively. Miniature inverted repeat transposable elements (MITEs) are one of the most high-copy-number DNA transposons, which are interspersed around rice genome and might influence nearby gene expression. In plants, 24-nucleotide (24-nt) heterochromatic small interfering RNAs (hc-siRNAs) derived from repeats and TEs. To what extent hc-siRNA associated TEs affect gene expression and therefore contribute to agricultural traits in rice remains elusi
