Fig. 3From: The transcriptional landscape of insect galls: psyllid (Hemiptera) gall formation in Hawaiian Metrosideros polymorpha (Myrtaceae)Venn diagram of genes present in all galled samples and genes present in at least one ungalled sample. Only two genes (Arabidopsis orthologues) have evidence of expression in all galled samples yet are absent in all ungalled samples. These genes are discussed in Results Back to article page
