Figure 3From: Identification of RNA silencing components in soybean and sorghumPhylogenetic tree of RDR genes in soybean, sorghum, Arabidopsis, and rice. All have one RDR1 and RDR2 genes, except soybean, which has two of each. Arabidopsis has three RDR3s, rice has two RDR3s, whereas soybean and sorghum have only one RDR3. While soybean, Arabidopsis, and rice have only one RDR6, sorghum has four RDR6s.Back to article page
