Figure S1. Correlation coefficients between signal intensities from wild-type and the ams anther replicates. Pearson's correlation coefficients were larger than 0.96 between pair of the biological replicates from the ams and wild type anther, indicating that the results were highly reproducible. Figures S2 & S3. GO annotation of genes up- and down-regulated in ams. GO categorization of genes differentially expressed in the ams mutant compared with wild type. The enriched groups were shown in different color with P-value provided. Figures S4-S11. The genes involved in different metabolic pathways that were activated or repressed in ams compared with wild type. Red color represents genes activated while green color represents genes repressed in ams compared with wild type. The overview of metabolism activities was shown in supplemental figure 4. Figure 5, 6, 7, 8-11 showed expression shifts of genes involved in secondary metabolism, regulatory pathways, receptor-like-kinase pathway, transcriptional regulation, protein trafficking, stress response, ubiquitin and autophagy dependent degradation pathway. Figure S12. Real-time PCR results consistent with microarray data. Six genes were verified using real-time PCR. The bars in blue represent the real-time RT-PCR results while red the microarray results. All the numbers shown in this figure are the fold changes of expression intensities in other tissues compared with anther. "infl" is the abbreviation of inflorescence.
