In both amphioxus and vertebrates, these both account for roughly 13,000 of the total genes. About 85 percent of the introns that interrupt genes are in identical locations in both groups.

Amphioxus, as a basal chordate, offers an insightful window into the evolutionary origins of vertebrate development. Its embryogenesis, characterised by the formation of a notochord, neural tube ...

On page 854 of this issue 1, Manzanares and co-workers describe how they have investigated the genes involved, working with gene sequences from the cephalochordate amphioxus (to picture this ...

Results of the study, entitled “Joint profiling of gene expression and chromatin accessibility during amphioxus development at single cell resolution,” were published in Cell Reports on June 21.

The marine invertebrate amphioxus offers baseline information for genetic roots of vertebrate innovation such as the adaptive immune systemResearch on the genome of a ...

The light-sensing cells of amphioxus, they discovered, may be the "missing link" between the visual cells of invertebrates and the circadian receptors in our own eyes. RELATED TOPICS.

Amphioxus is not widely known to the general public, but is gaining interest in scientific circles because of its position as one of the closest living invertebrate relatives of vertebrates. Although ...

In my lab, we are interested in understanding the developmental evolution of our own subphylum, the vertebrates. To do this, we study developmental gene expression, regulation, and function in three ...

During the evolution of invertebrates like amphioxus into vertebrates like fish, a remarkable structure appeared: the head. How, exactly, the head evolved has long been a mystery, but scientists ...

Schematic presentation of the main findings of this research: (1) a snRNA-seq atlas of amphioxus developmental embryos and multiple adult tissues and a scATAC-seq atlas of amphioxus developmental ...

This muscle development from an unsegmented territory is a specific characteristic of vertebrates, and in cephalochordates (i.e. amphioxus), invertebrates closely related to vertebrates, the paraxial ...

Why these fish-like invertebrates, also known as “amphioxus,” have this green glowing protein has both intrigued and puzzled scientists for nearly a decade. Today, Scripps Institution of Oceanography ...
