Figure 3

Gene dispensability and alternative splicing. Percentage of alternatively spliced genes according to gene dispensability in evolution. All the gene functions were present in the common ancestor of animals, plants and fungi. Dispensable genes (black): the KOG's to which they belong was lost in at least one of the animal or fungal species included in KOG database. Indispensable genes (grey): KOG's present in the seven studied species.
