Hierarchical cluster analysis of gene-expression patterns in six vegetative and reproductive organs of garlic. The heat map shows the relative expression levels of each contig (rows) in each sample (columns). Four identified gene clusters (shown in the left tree) are differentially expressed in one or more organs. Organs are clustered to reproductive and vegetative, with closer proximity between the roots and basal plates (upper tree). Expression values (FPKM) are log2-transformed and then median-centered by transcript.
