Figure 1.

Transcripts differentially expressed due to P_i. A total of 2,128 transcripts were identified as differentially expressed between P_i-sufficient and P_i-deficient tissues. To be considered differentially expressed, the transcript must have RPKM ≥ 3 in at least one tissue, 2-fold or greater change between tissues, and P ≤ 0.05. A, A total of 1,342 transcripts differentially expressed due to P_i in leaves. B, A total of 904 transcripts differentially expressed due to P_i in roots. C, Heat map of Z scores (number of sd) illustrating expression profiles of 2,128 transcripts differentially expressed due to P_i. Red indicates high expression, yellow indicates intermediate expression, and white indicates low expression. See also Supplemental Tables S1 and S2.
