Schematic diagram depicting a cross-sectional aspect of the P. maxima mantle organ and shell in situ. Mantle tissues used for the comparative differential gene expression analysis are labelled accordingly: inner fold (IF), middle fold (MF), outer fold (OF), ventral mantle (VM) and dorsal mantle (DM). Red lines denote the approximate position that dissections were made separating the five tissues used in the microarray comparative spatial analysis.
