Small RNAs in plants are protected by 2'-O-methylation at 3' terminal nucleotide by HEN1. In hen1 mutant, small RNAs lacking 3' methylation are truncated and tailed at 3' end. We identified a nucleotidyltransferase gene HESO1 in Arabidopsis that tails small RNAs in hen1. In order to study the small ...
