The sporophyte generation of the brown alga Ectocarpus sp. exhibits an unusualpattern of development compared with the majority of brown algae. The first cell division is symmetrical and the apical-basal axis is established late indevelopment. In the immediate upright (imm) mutant, the initial cell undergoes anasymmetric division to immediately establish the apical-basal axis. We provideevidence which suggests that this phenotype corresponds to the ancestral state ofthe sporophyte. The IMM gene encodes a protein of unknown function that contains a repeated motif also found in the EsV-1-7 gene of the Ectocarpus virus EsV-1.Brown algae possess large families of EsV-1-7 domain genes but these genes arerare in other stramenopiles, suggesting that the expansion of this family mighthave been linked with the emergence of multicellular complexity. EsV-1-7 domaingenes have a patchy distribution across eukaryotic supergroups and occur inseveral viral genomes, suggesting possible horizontal transfer during eukaryoteevolution.
