Functional categorization of Arabica differentially expressed genes (DEGs) in embryogenic calli compared to non-embryogenic calli. An additional stage, the non-embryogenic callus (NEC), was sampled at the same time as the embryogenic callus (C2). DEGs were compared against The Arabidopsis Information Resource database (TAIR, www.arabidopsis.org) using BLASTP with an e-value cut-off of 1 × 10−4. Functional categorization of Arabidopsis orthologs was performed using the Parametric Analysis of Gene set Enrichment (PAGE) tool in agriGO v2.0 . The PAGE tool yielded significant gene ontology (GO) terms that were classified in 11 biological processes. The x-axis corresponds to the different biological processes obtained and the y-axis corresponds to the Z-score values yielded by the PAGE tool
