Effect of RNAi of RNA processing and mRNA export proteins. RNAi was performed by injection of dsRNA homologous to the genes encoding proteins listed on the left. U1A/U2B" indicates RNAi of both rnp-2 and rnp-3 together. REF/Aly indicates simultaneous RNAi of the three genes: aly-1, aly-2, and aly-3. The number (n) of injected worms for each RNAi is shown in the second column. Each animal was scored for the level of GFP expression on day 3 and placed in one of the five categories shown in the next three columns. The fraction of animals in each category is reflected by the sizes of the circles. The darkness of the circles is a rough representation of the intensity of GFP in that category. Phenotypes of the offspring of the injected worms are given in the column on the right. (WT) Wild type; (emb) embryonic lethal; (gro) growth defect; (let) lethal.
