Gene clusters with inverse expression profiles exclusively in woolly fruits. Cluster 1 (left) contains 94 genes that have increased expression exclusively in fruits that are wooly (E4: R+, C+), whereas cluster 9 (right) contains 95 genes with decreased expression exclusively in these same fruits. The Gene Ontology annotations of the genes in these clusters are represented below each cluster. The number of genes associated with each GO term is represented by the color of the bars, as depicted in the scale presented in this figure. The dashed line indicates non-ripe fruits, E1 (R-, C-). To the left of the dashed line is the expression levels for ripe, juicy fruits, E2 (R+, C-). To the right of the dashed line are E3 (R-, C+) and E4 (R+, C+) fruits, non-ripe and ripe fruits that have undergone long-term cold storage, respectively. E4 (R+, C+) fruits are wooly. Annotations correspond to the parental plant GO Slim terms.
