Cluster Display of Differentially Expressed Genomic Fragments in Distinct Organs.

Centroid linkage hierarchical clustering was performed on transcription ratios of each organ versus cultured cells. Lane 1, panicle; lane 2, flag leaf; lane 3, tillering shoot; lane 4, seedling shoot; lane 5, seedling root. Only those gene models that exhibited differential expression among five organ samples were included. Differential expression was determined by the analysis of variance F test with P < 0.001. Each fragment must have expression detected in at least one organ sample. A total of 1915 fragments were included in this cluster analysis. Yellow indicates high levels of expression in a specific organ relative to cultured cells; blue indicates low levels compared with cultured cells; and gray indicates missing data. The dendrogram shows the relationship among organs based on expression.
