The transcription initiation sites of eggplant latent viroid strands map within distinct motifs in their in vivo RNA conformations.

Abstract excerpt

Eggplant latent viroid (ELVd), like other members of family Avsunviroidae, replicates in plastids through a symmetric rolling-circle mechanism in which elongation of RNA strands is most likely catalyzed by a nuclear-encoded polymerase (NEP) translocated to plastids. Here we have addressed where NEP initiates transcription of viroid strands. Because this step is presumably directed by sequence/structural motifs,...
