Fig. 3From: Expression of NK cluster genes in the onychophoran Euperipatoides rowelli: implications for the evolution of NK family genes in nephrozoansComparative transcriptomic analysis of expression of NK cluster genes and the NKL gene NK2.2 in the onychophoran E. rowelli. The diagram illustrates the relative expression levels of all identified NK cluster genes from different transcriptome libraries of partially pooled embryonic stages. The number of transcripts of RPL31 (gene encoding a ribosomal protein) was used as a referenceBack to article page
