Key result
ARC-1 inserts complementary to plant 18S rRNA increase mRNA translation efficiency ~3-fold over controls.
Why the study?
The mechanism by which plant viral leader sequences enhance translation efficiency via complementarity to 18S rRNA was not fully understood.
Effect estimate: more than three times more efficiently
Complementary interaction between mRNA leader and the central region of 18S rRNA allows cap-independent binding of mRNA to the 43S pre-initiation complex in plant systems.

May guide plant mRNA engineering; leaves open whether 18S complementarity enhances translation in mammalian or therapeutic systems.
Rashid Akbergenov (2004) studied this question. ARC-1 inserts complementary to plant 18S rRNA vs. Control lacking complementarity was evaluated on Translation efficiency (more than three times more efficiently). mRNAs with leaders containing ARC-1 inserts complementary to plant 18S rRNA were translated more than three times more efficiently than controls lacking such complementarity.
