Functional categories of kiwi genes. A. Functional classifications are as described in the Gene Ontology Consortium http://www.geneontology.org. B. Classification of genes are based on their involvement in various pathways as categorized by the KEGG pathways database http://www.genome.jp/kegg/pathway.html. The functions and pathway involvement of kiwi genes were deduced from their chicken counterparts for which gene ontology functions or KEGG pathway information were available.
