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.

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.

This issue sees the publication of the draft genome sequence of an animal that has been studied by biologists for many years as a model for a primitive chordate. The amphioxus or lancelet is a ...

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 ...

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

In a primitive marine organism, scientists find photosensitive cells that may be ancestral to the "circadian receptors" in the mammalian retina.

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 ...

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 ...

Studying the amphioxus to understand how the vertebrate head was formed This muscle development from an unsegmented territory is a specific characteristic of vertebrates, and in cephalochordates (i.e.

Shine a blue light on a lancelet and it glows green. Why these fish-like invertebrates, also known as “amphioxus,” have this green glowing protein has both intrigued and puzzled scientists for nearly ...
