Functional classification of DEGs from carotenoid accumulating roots. DEGs from PSY-overexpressing, carotenoid-accumulating Arabidopsis roots with at least 2-fold differences to WT levels were functionally classified using the PANTHER tool. The percentage of genes from the Arabidopsis genome associated with a molecular function (A) and biological process categories (B) was used to compare the corresponding percentage of DEGs from carotenoid accumulating roots associated with the same categories. Changes in abundance indicate that the corresponding process might be affected.
