چکیده انگلیسی
To understand the process of bilaterian evolution, we estimated ancestral gene sets at the split of plant-animal-fungi and the divergence of bilaterian animals and from 1,236,790 non-redundant genes. We, then, examined how the numbers of the gene clusters have changed since the split. As a result, we estimated the numbers of gene clusters in the ancestral gene sets of plant-animal-fungi and bilaterian animals to be at least 2469 and 6577, respectively. Thus, we found a 2.7-fold increase in the number of gene clusters during the period from the evolutionary split of plant-animal-fungi to the divergence of bilaterian animals. Moreover, when we compared these numbers of ancestral gene clusters with those of extant animals such as the nematode, fly, mouse and human, we found that the extant bilaterian animals have retained more than 3500 gene clusters of the ancestral gene set, and have lost more than 1600 gene clusters. It suggests that these processes of genomic diversification provided bilaterian animals with molecular basis for species diversity.
