| 英文摘要 | Cephalochordates, urochordates, and vertebrates comprise the three extant groups of chordates. although higher morphological and developmental similarity exists between cephalochordates and vertebrates, molecular phylogeny studies have instead suggested that the morphologically simplified urochordates are the closest relatives to vertebrates. micrornas (mirnas) are regarded as the major factors driving the increase of morphological complexity in early vertebrate evolution, and are extensively characterized in vertebrates and in a few species of urochordates. however, the comprehensive set of mirnas in the basal chordates, namely the cephalochordates, remains undetermined. through extensive sequencing of a small rna library and genomic homology searches, we characterized 100 mirnas from the cephalochordate amphioxus, branchiostoma japonicum, and b. floridae. analysis of the evolutionary history of the cephalochordate mirnas showed that cephalochordates possess 54 mirna families homologous to those of vertebrates, which is threefold higher than those shared between urochordates and vertebrates. the mirna contents demonstrated a clear correlation between the extent of mirna overlapping and morphological similarity among the three chordate groups, providing a strong evidence of mirnas being the major genetic factors driving morphological complexity in early chordate evolution. |
