Mobile 24 nt small RNAs direct transcriptional gene silencing in the root meristems of Arabidopsis thaliana


ABSTRACT: We grafted Transcriptional Gene Silencing (TGS)-inducing wild type Arabidopsis and a mutant that is compromised in 24 nucleotide (nt) small RNA (sRNA) production onto a wild type reporter line. We observed that 21-24 nt sRNAs were transmitted across a graft union yet only the 24 nt sRNAs directed RNA-dependent DNA methylation (RdDM) and TGS of a transgene promoter in meristematic cells.
