From: Identification of RNA silencing components in soybean and sorghum
Domain compositions of DCL genes in soybean, sorghum, and Arabidopsis. All DCLs have major domains: DExD-helicase, helicase-C, Duf283 (now called dsRNA-binding domain), PAZ, RNase III (two), and dsRB (shown as dsrm in the figure), except AtDCL3, which missed the dsRNA-binding domain. The first RNase III domain in SbDCL1 is separated into two segments, and the first dsrm domain in SbDCL3b appears between dsRNA-binding and PAZ domains.
