Figure 4.

Heat map of the relative expression level of 3,376 P. xuthus genes by microarray results. Red and green indicate higher and lower expression level, respectively. The stage-specific co-expression clusters are shown right. C: constantly expressed genes; IM3: genes enriched in the intermolt of the third instar; IM3-4: genes enriched in the intermolt of both the third and the fourth instar; IM4: genes enriched in the intermolt of the fourth instar; EM3: genes enriched in the early stage of the third molt; EM3-4: genes enriched in the early stage of both the third and the fourth molts; EM4: genes enriched in the early stage of the fourth molt; MM3: genes enriched in the middle stage of the third molt; MM3-4: genes enriched in the middle stage of both the third and the fourth molts; MM4: genes enriched in the middle stage of the fourth molt; LM3: genes enriched in the late stage of the third molt; LM3-4: genes enriched in the late stage of both the third and the fourth molts; LM4: genes enriched in the late stage of the fourth molt. Stage and marking of each sample is shown above (for example, 4-10E, eyespot at 10 hours after head capsule slippage of the fourth molting period). Red indicates positive values and green indicates negative values (color spectrum bar is shown left; N.D., not detected). See also Figure 2.
