Figure 1.

Supervised average linkage clustering analysis of 310 genes in the rainbow trout ovary during late vitellogenesis (Late Vit), post vitellogenesis (post-Vit) and oocyte maturation. Each row represents a gene and each column represents an ovarian RNA sample. The dendrogram on the left represents correlation distances between the profiles of studied genes. The 17 samples are supervised according to the natural time-course of oogenesis. For each gene the expression level within sample set is indicated using a color intensity scale. Red and green are used for over and under expression respectively while black is used for median expression.
