Hierarchical clustering of 607 tomato genes expressed in developing fruit. A, Each gene is represented by a single row of colored boxes. The five columns represent the different organs: fruit at 8 DPA (8), fruit at 15 DPA (15), leaf (L), root (R), and seed (S). Induction (or repression) ranges from pale to saturated red (or green). B, Four clusters showing distinctive expression profiles of genes preferentially expressed in fruit and root (Groups Ia and Ib) and in fruit and leaf (Group IIa and IIb) are presented. N indicates the number of transcripts in each group.
