Abstract:
The digestive methods employed by amphioxus ( Branchiostoma )—both intracellular phagocytic digestion and extracellular digestion—have been discussed since 1937. Recent studies also show that epithelial cells lining the Branchiostoma digestive tract can express many immune genes. Here, in Branchiostoma belcheri , using a special tissue fixation method, we show that some epithelial cells, especially those lining the large diverticulum protruding from the gut tube, phagocytize food particles directly, and Branchiostoma can rely on this kind of phagocytic intracellular digestion to obtain energy

Abstract:
As the extant representatives of the basal chordate lineage, amphioxi (including the genera Branchiostoma, Asymmetron and Epigonichthys) play important roles in tracing the state of chordate ancestry. Previous studies have reported that members of the Branchiostoma species have similar morphological phenotypic characteristics, but in contrast, there are high levels of genetic polymorphisms in the populations. Here, we resequenced 20 Branchiostomabelcheri genomes to an average depth of approximately 12.5X using the Illumina HiSeq 2000 platform. In this study, over 52 million variations (~12% of

Abstract:
Thyroid hormone (TH) is important for metamorphosis in many species, including the cephalochordate Branchiostoma floridae, a marine invertebrate (amphioxus) living in warmer coastal areas. Branchiostoma expresses a TH receptor, which is activated by 3,3′,5-triiodothyroacetic acid (TA3) but not by T3. The Branchiostoma genome also contains multiple genes coding for proteins homologous to iodothyronine deiodinases in vertebrates, selenoproteins catalyzing the activation or inactivation of TH. Three Branchiostoma deiodinases have been cloned: two have a catalytic Sec, and one, bfDy, has a Cys res

Abstract:
Amphioxi represent the evolutionary link between vertebrates and invertebrates. For this reason, research dealing with these animals has been focused mainly on embryological and anatomical studies. Out of 30 described species, only one, Branchiostoma elongatum, is known to inhabit shallow sandy bottoms along the Humboldt Current System (HCS) of Chile and Peru. The population dynamics of B. elongatum from northern Chile was studied between February 2008 and January 2009, and the results were compared with other species within the genus Branchiostoma inhabiting distinct ecosystems.

These coelomocytes probably originate from the coelomic lining, but autoradiography failed to substantiate this. T

The ParaHox cluster is the evolutionary sister of the Hox cluster. Like the Hox cluster, the ParaHox cluster is subject to complex regulatory phenomena such as collinearity. Despite the breakup of the ParaHox cluster within many animals, intact and collinear clusters have now been discovered within the chordate phyla in amphioxus and the vertebrates, and more recently within the hemichordates and echinoderms. The archetypal ParaHox cluster of amphioxus places it in a unique position in which to examine the regulatory mechanisms controlling ParaHox gene expression within the last common ancesto

Nitric Oxide (NO) is a gaseous molecule that acts in a wide range of biological processes. NO can be produced by enzymatic and non-enzymatic pathways and, in this scenario, the enzyme Nitric Oxide Synthase (NOS) has a great importance for its exclusive role in <i>de novo</i> synthesis of NO. In the present study, the role of the NO in the embryonic development was investigated in the cephalochordate <i>Branchiostoma lanceolatum</i> (amphioxus) with the purpose of acquiring further knowledge on the ancestral role of animal <i>Nos</i> and the acquisition of new NO functions during evolution.
