However , only three species of the cephalochordate including b . lanceolatum , b . floridae , and b . belcheri , have so far been studied for their chromosome numbers , and the karyotypic analysis and banding study of amphioxus chromosomes remains largely untouched Floridae 、 b belcheri三種文昌魚染色體數目。有關文昌魚染色體核型和帶型的研究尚未見任何報道,文昌魚染色體核型和帶型的研究將為比較基因組學和細胞遺傳學研究提供珍貴的背景資料。

Amphioxus or lancelet , a cephalochordate , has long been regarded as the living invertebrate most closely related to the proximate invertebrate ancestor of vertebrates 在動物的進化歷程中,文昌魚是介于無脊椎動物與脊椎動物之間的過渡類型。

Here , we report the results of the study on the complement system of the cephalochordate amphioxus and lower vertebrates lip shark and grass carp 本文選擇了在系統演化上占據主要地位的文昌魚以及軟骨魚和硬骨魚,對它們的補體系統進行了研究。

Amphioxus or lancelet , a cephalochordate , is the extant invertebrate chordate considered to be the closest relationship to the vertebrates 文昌魚被認為是和脊椎動物親緣關系最近的動物。
