Developmental timing of accumulation of selected AZ551 transcripts. Entries listed above the dashed line are downregulated at least 2-fold between stages; those listed below the dashed line are upregulated at least 2-fold. Maximum negative and positive fold-changes between stages are in bold type. Corresponding quantitative data and additional locus IDs are in Table S2. 12
