Gene expression profiling during rainbow trout late oogenesis Supervised average linkage clustering analysis of 1200 clones in rainbow trout ovary during late vitellogenesis (LV, n = 3), post-vitellogenesis (PV, n = 4) and during maturation (Mat., n = 6). Each row represents a gene and each column an ovarian RNA sample. The 13 samples are supervised according to the natural time-course of oogenesis. Data were log2-transformed and median-centered prior to the clustering analysis. For each gene the expression level within sample set is indicated using a color density scale. Red and green are used for over- and under-expression respectively, while black is used for median expression.
