Figure 3.

A comparison of the genetic pathways that regulate RNAi and vulval development. A subset of the synthetic Multivulva B genes, designated the synMuv B(R) genes, negatively regulate vulval induction (redundantly with the synMuv A pathway), and also negatively regulate somatic and germline RNAi. In both processes the genes mes-4 and zfp-1 act genetically downstream of, or in parallel to, the synMuv B(R) genes. The identities of the synMuv B(R) genes are given below the figure.
