Fig. 8From: Comparative transcriptomics of early petal development across four diverse species of Aquilegia reveal few genes consistently associated with nectar spur developmentGenes up-regulated in spurred taxa and in the spur cup of A. coerulea “Origami”. Mean normalized read counts across three biological replicates for each species and developmental stage. The error bars represent the standard error of the three biological replicates used to calculate the mean. Key: A. ecalcarata = lavender, A. sibirica = blue, A. formosa = red, and A. chrysantha = yellowBack to article page
