The dsRNA-binding protein DRB4 interacts with the Dicer-like protein DCL4 in vivo and functions in the trans-acting siRNA pathway.

Abstract excerpt

Arabidopsis thaliana encodes four Dicer-like (DCL) proteins and five dsRNA-binding (DRB) proteins. We have previously demonstrated that DCL4 specifically interacts with DRB4 in vitro. Here we describe the interaction between DCL4 and DRB4 in vivo. The phenotype of a mutant with a defect in DCL4 (dcl4-2) was similar to that of a mutant with a defect in DRB4 (drb4-1): both mutant plants had elongated and downwardly...
