Amphioxus, a small marine organism belonging to the cephalochordates, serves as a crucial model for understanding the evolution of vertebrates and the development of chordates. Its simple body ...

The study of the processes by which marine organisms grow and how factors such as temperature, nutrition, microbes, predators, and hormones influence development. (Green fluorescent amphioxus photo by ...

In some ways this effect, described here as a putative innate immune receptor, is reminiscent of the high level of complexity seen in other innate immune receptors in amphioxus and sea urchins.

The identification of distinct waves of progenitors during development, each corresponding to a specific time, space, and function, provided the basis for the concept of a “layered” organization in ...

In the promoter analysis experiment, the upstream 3 kb DNA sequence of Nas15 was amplified by PCR using genomic DNA from C. robusta as a template with primers Nas15 (3 k) -F and Nas15 (3k) -R. The PCR ...
