Figure 2. Distributions of Transcripts in the Three Subcellular Fractions.

Figure 2

(A) RefSeq genes exceeding 400-bp in length and exhibiting an RPKM of at least one in one of the samples were divided into 12 clusters on the basis of their pattern of transcript levels in the three subcellular fractions and five time points. Colors indicate the percentile of the relative expression level.

(B) The average relative transcript levels within representative clusters are shown. Although relative cluster-to-cluster differences are of interest, absolute transcript abundances in each sub-cellular compartment cannot be determined because of possible variability in RNA isolation efficiencies from the three fractions.

(C) The number and percentage (parenthesis) of genes within each of the 12 clusters in panel A are shown. See also Figure S2.
