Figure 3A,B. Comparison of Northern Blot to Microarray Results.

(A) Samples from the indicated time points were assayed by Northern analysis. Genes were chosen to be representative of the four previously identified temporal classes. DMC1, SPS1, DIT1, and SPS100 belong to the early, middle, mid-late, and late classes, respectively. (B) Data from the microarray analysis of RNA samples from the same time course are graphically displayed using color to represent the quantitative changes. Increases in mRNA (relative to pre-sporulation levels) are shown as shades of red and decreases in mRNA levels are represented by shades of green.
