Functional classification of differentially expressed genes in LEC1-OXi transgenic plants

Functional classification of the differentially expressed genes was performed using the biological process category of Arabidopsis Gene Ontology (http://www.geneontology.com). Percentage (far right column) refers to the ratio of genes of each functional category relative to total up-regulated or down-regulated differentially expressed genes identified in the microarray experiment.
