The ripening papaya transcriptome was studied using the cross-species microarray technique and the Affymetrix ATH1- 121501 GeneChip from A. thaliana. A) Papaya normalized gene expression values were subjected to an analysis to identify overrepresented functional categories using PageMan (indicated by arrows and names). Gene expression data are presented as log₂ fold changes in comparison with the unripe fruit. The data were subjected to a Wilcoxon test, and the results are displayed in false-color code. Red colored bins are significantly up-regulated, whereas blue colored bins are significantly down-regulated (p <0.05). All non-significant categories and some down-regulated bins are collapsed in the display. B) Pie chart showing the percentage of genes in ripe papaya that are over represented with respect to each of the GO biological processes.
