Coordinate Replication of Alfalfa Mosaic Virus RNAs 1 and 2 Involves cis- and trans-Acting Functions of the Encoded Helicase-Like and Polymerase-Like Domains.

Reports on the study of cis- and trans-acting functions of the helicase-like domain replicase proteins (RP) by agroinfiltration plant leaves. Synthesis of minus-strand RNAs in mutations of conserved motifs; Inability of transient RP to complement the defect in RNA replication; Existence of a mechanism which coordinates the RNA replication.
