Fig. 9
Expression patterns of the ABC genes in multiple developmental stages and tissues of P. xylostella based on RPKM values. The relative expression levels are illustrated by seven scaled colors and corresponding log2 RPKM values (Additional file 13) ranging from −3.00 to +3.00. Tissue-specific expression profiling was performed using multiple tissues (if not specified) of the 4th larvae as shown on the top of the figure. The colors vary from bright red showing up-regulated expression to bright purple for down-regulated genes
