Figure 2From: Concurrent transcriptional profiling of Dirofilaria immitis and its Wolbachia endosymbiont throughout the nematode life cycle reveals coordinated gene expressionVenn diagram showing stage-specific expression of the 834 filarial (shared between D . immitis and B . malayi ) genes. Stage-specificity (up to three stages) for each gene was determined for each using differential expression testing by Cuffdiff (Additional file 4: Table S2, q < 0.01). Only life cycle stages expressing the gene (value >0) were considered.Back to article page
