DCL4

Plant gene encoding a Dicer-like protein

DCL4 (Dicer-like 4) is a plant gene that encodes an enzyme involved in RNA silencing, a process by which cells regulate gene expression and defend against

DCL4

Trans-acting siRNA

Class of small interfering RNA

RNA by RDR6. The resulting dsRNA is further processed by the Dicer-like 4 (DCL4) enzyme to produce a phased array of 21-nt siRNAs from positions adjoining

DCL1

Protein coding gene in plants

additional downstream plant-specific pathways, where DCL1 paralogs like DCL4 participate, such trans-acting siRNA biogenesis. DCL1 is localized exclusively

DCL1

Dicer

Enzyme that cleaves double-stranded RNA (dsRNA) into short dsRNA fragments

Dicer-like-encoding genes have been described and are designated DCL1 to DCL4; there are four Dicer family proteins encoded in a typical eudicot genome

Dicer

DCL3

"Ribonucleases", "Gene silencing", "non-coding RNAs", "Plant proteins", "Protein stubs"

in plant genomes. Unlike DCL1, which primarily generates microRNAs, and DCL4, which produces 21-nucleotide siRNAs, DCL3 is specialized for the biogenesis

DCL3

RNA-directed DNA methylation

RNA-based gene silencing process

converted into dsRNA by RDR6 and then processed into 21-22 nt sRNAs by DCL2 or DCL4. Most of these 21-22 nt sRNAs are loaded into AGO1 and feed back into PTGS

DCL2

Dicer-like gene in plants

there are mainly four Dicer-like proteins (DCL): DCL1, DCL2, DCL3, and DCL4. They all contain five domains, following the order from N-terminus to C-terminus:

DCL5

Plant gene encoding a Dicer-like protein

later renamed DCL5) responsible for 24-nt phasiRNA production, distinct from DCL4, which generates 21-nt phasiRNAs. Unlike DCL3, which processes RNA polymerase

RNA silencing suppressor p19

Viral protein

RNA (siRNA) and is specialized for the 21-nucleotide product of the enzyme DCL4 (a member of a family of plant enzymes with homology to Dicer). By binding
