Analysis of microarray data and comparison of 6,688 gene expression levels between acephate-susceptible (LLS) and –resistant (LLR) tarnished plant bugs using ArrayStar software.

<p><b>A</b>: Hierarchical clustering analysis of 329 up-regulated and 333 down-regulated genes (≥2-fold, <i>P</i><0.05) in the LLR. Each column represented a sample (LLS or LLR) and each row represented a gene. The gray scale depicted the relative levels of gene expressions from low to high with corresponding grayscale from light (for lower expression) to dark (for higher levels). <b>B</b>: Scatter-plot comparison of 6,688 gene expression levels between LLS and LLR. The dots of the scatter plot in the upper left corner represented up-regulated genes, and the dots in low right corner represented down-regulated genes. Dots above line 2a and below line 2b represent up- and down-regulated genes by 2-fold; Dots above line 4a and below line 4b represent up- and down-regulated genes by 4-fold; Dots above line 8a and below line 8b represent up- and down-regulated genes by 8-fold.
