Figure 4.
Hierarchical cluster analysis of gene-expression patterns at the three developmental stages of garlic genotypes F87 and MS96 shows the relative expression levels of each gene (column) in each sample (row). Two large (1, 2) and three small gene clusters were differentially expressed in one or more samples. The expression values (FPKM; average of three replications) were log2-transformed and then median-centered by transcript.
