Arabidopsis terminal nucleotidyl transferases govern secondary siRNA production at distinct steps
M. L. Vigh, A. Thieffry, L. Arribas-Hernandez, P. Brodersen
This study identifies two roles of terminal nucleotidyl transferases (TNTases) in secondary siRNA amplification in Arabidopsis, showing URT1 inhibits initiation while HESO1 and others promote siRNA formation by modifying dsRNA.
