The role of RNA interference in heterochromatic silencing
Article Abstract:
The way heterochromatic silencing depends on the processing of repeat RNA transcripts into short interfering RNAs (siRNAs), which then direct chromatin modification is presented. RNAi provides a mechanism for programmed, sequence-specific silencing by means of heterochromatic modifications, which is vital for silencing transposons and repeats and it is concluded that heterochromatic silencing could prove to be important over a longer timeframe in population genetics and evolution.

Control of leaf morphogenesis by microRNAs
Article Abstract:
Research reveals that Arabidopsis microRNAs exhibit sequence complementarity to TCP genes and that they guidemessenger RNA cleavage of TCP genes that control leaf development. Data indicate that TCP genes containing microRNA target sequences are distributed among the plant species, suggesting that microRNA's control of leaf morphogenesis is conserved.
