ROLE OF THE GAMETE MEMBRANES IN FERTILIZATION IN SACCOGLOSSUS KOWALEVSKII (ENTEROPNEUSTA). I. THE ACROSOMAL REGION AND ITS CHANGES IN EARLY STAGES OF FERTILIZATION. (1/153)

Previous electron microscope studies of sperm-egg association in the annelid Hydroides revealed novel aspects with respect to the acrosomal region. To determine whether these aspects were unique, a comparable study was made of a species belonging to a widely separated phylum, Hemichordata. Osmium tetroxide-fixed polyspermic material of the enteropneust, Saccoglossus, was used. The acrosomal region includes the membrane-bounded acrosome, with its large acrosomal granule and shallow adnuclear invagination, and the periacrosomal material which surrounds the acrosome except at the apex; here, the acrosomal membrane lies very close to the enclosing sperm plasma membrane. After reaching the egg envelope, the spermatozoon is activated and undergoes a series of changes: the apex dehisces and around the resulting orifice the acrosomal and sperm plasma membranes form a continuous mosaic membrane. The acrosomal granule disappears. Within 7 seconds the invagination becomes the acrosomal tubule, spans the egg envelopes, and meets the egg plasma membrane. The rest of the acrosomal vesicle everts. The periacrosomal mass changes profoundly: part becomes a fibrous core (possibly equivalent to a perforatorium); part remains as a peripheral ring. The basic pattern of structure and sperm-egg association in Saccoglossus is the same as in Hydroides. Previous evidence from four other phyla as interpreted here also indicates conformity to this pattern. The major role of the acrosome is apparently to deliver the sperm plasma membrane to the egg plasma membrane.  (+info)

ROLE OF THE GAMETE MEMBRANES IN FERTILIZATION IN SACCOGLOSSUS KOWALEVSKII (ENTEROPNEUSTA). II. ZYGOTE FORMATION BY GAMETE MEMBRANE FUSION. (2/153)

An earlier paper showed that in Saccoglossus the acrosomal tubule makes contact with the egg plasma membrane. The present paper includes evidence that the sperm and egg plasma membranes fuse to establish the single continuous zygote membrane which, consequently, is a mosaic. Contrary to the general hypothesis of Tyler, pinocytosis or phagocytosis plays no role in zygote formation. Contact between the gametes is actually between two newly exposed surfaces: in the spermatozoon, the surface was formerly the interior of the acrosomal vesicle; in the egg, it was membrane previously covered by the egg envelopes. The concept that all the events of fertilization are mediated by a fertilizin-antifertilizin reaction seems an oversimplification of events actually observed: rather, the evidence indicates that a series of specific biochemical interactions probably would be involved. Gamete membrane fusion permits sperm periacrosomal material to meet the egg cytoplasm; if an activating substance exists in the spermatozoon it probably is periacrosomal rather than acrosomal in origin. The contents of the acrosome are expended in the process of delivering the sperm plasma membrane to the egg plasma membrane. After these membranes coalesce, the sperm nucleus and other internal sperm structures move into the egg cytoplasm.  (+info)

AN UNUSUAL CONFIGURATION OF THE GOLGI COMPLEX IN PIGMENT-PRODUCING "TEST" CELLS OF THE OVARY OF THE TUNICATE, STYELA. (3/153)

The test cell in the ovary of the tunicate Styela contains a large and robust Golgi complex which demonstrates a regional structural differentiation. In one of the regions, branching of the lamellae occurs resulting in a honeycomb or lattice-type arrangement. Small, dense granules or homogeneous material of moderate density may be present within certain of the Golgi cisternae. The close association, or continuity in some cases, between elements of the Golgi complex and immature forms of pigment suggests that the Golgi complex in these cells is involved in pigment formation. These relationships are shown and discussed in terms of possible functional significance.  (+info)

A CYTOCHEMICAL STUDY OF CYTOPLASMIC BASIC PROTEINS IN THE ASCIDIAN OOCYTE. (4/153)

The cytoplasm of young oocytes of the ascidians contains high concentrations of proteins which are stainable with alkaline fast green at pH 8.1 and above. These proteins cannot be stained even with acid dyes at low pH unless RNA is removed. Deamination and formalin blockage of amino groups is incapable of destroying the net positive charge on these protein molecules in the presence of RNA, but these treatments destroy the charge if RNA is removed. It is therefore concluded that basic proteins and RNA exist as a nucleoprotein complex in the ribosomes of these young oocytes. The detectable RNA of the mature oocytes and unfertilized eggs shows no evidence of being associated with basic proteins.  (+info)

Amphioxus and ascidian Dmbx homeobox genes give clues to the vertebrate origins of midbrain development. (5/153)

The ancestral chordate neural tube had a tripartite structure, comprising anterior, midbrain-hindbrain boundary (MHB) and posterior regions. The most anterior region encompasses both forebrain and midbrain in vertebrates. It is not clear when or how the distinction between these two functionally and developmentally distinct regions arose in evolution. Recently, we reported a mouse PRD-class homeobox gene, Dmbx1, expressed in the presumptive midbrain at early developmental stages, and the hindbrain at later stages, with exclusion from the MHB. This gene provides a route to investigate the evolution of midbrain development. We report the cloning, genomic structure, phylogeny and embryonic expression of Dmbx genes from amphioxus and from Ciona, representing the two most closely related lineages to the vertebrates. Our analyses show that Dmbx genes form a distinct, ancient, homeobox gene family, with highly conserved sequence and genomic organisation, albeit more divergent in Ciona. In amphioxus, no Dmbx expression is observed in the neural tube, supporting previous arguments that the MHB equivalent region has been secondarily modified in evolution. In Ciona, the CiDmbx gene is detected in neural cells caudal to Pax2/5/8-positive cells (MHB homologue), in the Hox-positive region, but, interestingly, not in any cells rostral to them. These results suggest that a midbrain homologue is missing in Ciona, and argue that midbrain development is a novelty that evolved specifically on the vertebrate lineage. We discuss the evolution of midbrain development in relation to the ancestry of the tripartite neural ground plan and the origin of the MHB organiser.  (+info)

Retroelement dynamics and a novel type of chordate retrovirus-like element in the miniature genome of the tunicate Oikopleura dioica. (6/153)

Retrotransposable elements have played an important role in shaping eukaryotic DNA, and their activity and turnover rate directly influence the size of genomes. With approximately 15,000 genes within 65-75 megabases, the marine tunicate Oikopleura dioica, a nonvertebrate chordate, has the smallest and most compact genome ever found in animals. Consistent with a massive elimination of retroelements, only one apparently novel clade of non-long terminal repeat (non-LTR) retrotransposons was detected within 41 megabases of nonredundant genomic sequences. In contrast, at least six clades of non-LTR elements were identified in the less compact genome of the tunicate Ciona intestinalis. Unexpectedly, Ty3/gypsy-related Tor LTR retrotransposons presented an astonishing level of diversity in O. dioica. They were generally poorly or apparently not corrupted, indicating recent activity. Both Tor3 and Tor4b families bore an envelope-like open reading frame, suggesting possible horizontal acquisition through infection. The Tor4b envelope-like gene might have been obtained from a paramyxovirus (RNA virus). Tor3 and Tor4b are phylogenetically clearly distinct from vertebrate retroviruses (Retroviridae) and are more reminiscent of certain insect and plant sequences. Tor elements potentially represent a so far unknown, ancient type of infectious retroelement in chordates. Their distribution and transmission dynamics in tunicates and other chordates deserve further study.  (+info)

Bayesian inference of the metazoan phylogeny; a combined molecular and morphological approach. (7/153)

Metazoan phylogeny remains one of evolutionary biology's major unsolved problems. Molecular and morphological data, as well as different analytical approaches, have produced highly conflicting results due to homoplasy resulting from more than 570 million years of evolution. To date, parsimony has been the only feasible combined approach but is highly sensitive to long-branch attraction. Recent development of stochastic models for discrete morphological characters and computationally efficient methods for Bayesian inference has enabled combined molecular and morphological data analysis with rigorous statistical approaches less prone to such inconsistencies. We present the first statistically founded analysis of a metazoan data set based on a combination of morphological and molecular data and compare the results with a traditional parsimony analysis. Interestingly, the Bayesian analyses demonstrate a high degree of congruence between morphological and molecular data, and both data sets contribute to the result of the combined analysis. Additionally, they resolve several irregularities obtained in previous studies and show high credibility values for controversial groups such as the ecdysozoans and lophotrochozoans. Parsimony, on the contrary, shows conflicting results, with morphology being congruent to the Bayesian results and the molecular data set producing peculiarities that are largely reflected in the combined analysis.  (+info)

Evolutionary relationships of Aurora kinases: implications for model organism studies and the development of anti-cancer drugs. (8/153)

BACKGROUND: As key regulators of mitotic chromosome segregation, the Aurora family of serine/threonine kinases play an important role in cell division. Abnormalities in Aurora kinases have been strongly linked with cancer, which has lead to the recent development of new classes of anti-cancer drugs that specifically target the ATP-binding domain of these kinases. From an evolutionary perspective, the species distribution of the Aurora kinase family is complex. Mammals uniquely have three Aurora kinases, Aurora-A, Aurora-B, and Aurora-C, while for other metazoans, including the frog, fruitfly and nematode, only Aurora-A and Aurora-B kinases are known. The fungi have a single Aurora-like homolog. Based on the tacit assumption of orthology to human counterparts, model organism studies have been central to the functional characterization of Aurora kinases. However, the ortholog and paralog relationships of these kinases across various species have not been rigorously examined. Here, we present comprehensive evolutionary analyses of the Aurora kinase family. RESULTS: Phylogenetic trees suggest that all three vertebrate Auroras evolved from a single urochordate ancestor. Specifically, Aurora-A is an orthologous lineage in cold-blooded vertebrates and mammals, while structurally similar Aurora-B and Aurora-C evolved more recently in mammals from a duplication of an ancestral Aurora-B/C gene found in cold-blooded vertebrates. All so-called Aurora-A and Aurora-B kinases of non-chordates are ancestral to the clade of chordate Auroras and, therefore, are not strictly orthologous to vertebrate counterparts. Comparisons of human Aurora-B and Aurora-C sequences to the resolved 3D structure of human Aurora-A lends further support to the evolutionary scenario that vertebrate Aurora-B and Aurora-C are closely related paralogs. Of the 26 residues lining the ATP-binding active site, only three were variant and all were specific to Aurora-A. CONCLUSIONS: In this study, we found that invertebrate Aurora-A and Aurora-B kinases are highly divergent protein families from their chordate counterparts. Furthermore, while the Aurora-A family is ubiquitous among all vertebrates, the Aurora-B and Aurora-C families in humans arose from a gene duplication event in mammals. These findings show the importance of understanding evolutionary relationships in the interpretation and transference of knowledge from studies of model organism systems to human cellular biology. In addition, given the important role of Aurora kinases in cancer, evolutionary analysis and comparisons of ATP-binding domains suggest a rationale for designing dual action anti-tumor drugs that inhibit both Aurora-B and Aurora-C kinases.  (+info)

Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. A robust mining of GPCR families in fungal genomes (Paper I) provides the first evidence that homologs of the mammalian families of GPCRs, including Rhodopsin, Adhesion, Glutamate and Frizzled are present in Fungi. These findings further support the hypothesis that all main GPCR families share a common origin. Moreover, we clarified the evolutionary hierarchy by showing for the first time that Rhodopsin family members are found outside metazoan lineages. We also characterized the GPCR superfamily in two important model organisms (Amphimedon queenslandica and Saccoglossus kowalevskii) that belong to different ...

Conway Morris and Caron (2012) have recently published an account of virtually all the available information on Pikaia gracilens, a well-known Cambrian fossil and supposed basal chordate, and propose on this basis some new ideas about Pikaias anatomy and evolutionary significance. Chief among its chordate-like features are the putative myomeres, a regular series of vertical bands that extends the length of the body. These differ from the myomeres of living chordates in that boundaries between them (the myosepta) are gently curved, with minimal overlap, whereas amphioxus and vertebrates have strongly overlapping V- and W-shaped myomeres. The implication, on biomechanical grounds, is that myomeres in Pikaia exerted much less tension on the myosepta, so the animal would have been incapable of swimming as rapidly as living chordates operating in the fast-twitch mode used for escape and attack. Pikaia either lacked the fast-twitch fibers necessary for such speeds, having instead only slow-twitch fibers, or

The death receptor (DR)-mediated apoptosis pathway is thought to be unique to vertebrates. However, the presence of DR-encoding genes in the sea urchin and the basal chordate amphioxus prompted us to reconsider, especially given that amphioxus contains 14 DR proteins and hundreds of death domain (DD)-containing adaptor proteins. To understand how the extrinsic apoptotic pathway was originally established and what the differences in signaling are between invertebrates and vertebrates, we performed functional studies of several genes that encode DDs in the amphioxus Branchiostoma belcheri tsingtauense (Bbt). First, we observed that the increased abundance of Bbt Fas-associated death domain 1 (BbtFADD1) in HeLa cells resulted in the formation of death effector filamentous structures in the cytoplasm and the activation of the nuclear factor κB pathway, whereas BbtFADD2 protein was restricted to the nucleus, although its death effector domain induced apoptosis when in the cytoplasm. We further ...

A common feature of chemosensory systems is the involvement of G protein-coupled receptors (GPCRs) in the detection of environmental stimuli. Several lineages of GPCRs are involved in vertebrate olfaction, including trace amine-associated receptors, type 1 and 2 vomeronasal receptors and odorant receptors (ORs). Gene duplication and gene loss in different vertebrate lineages have lead to an enormous amount of variation in OR gene repertoire among species; some fish have fewer than 100 OR genes, while some mammals possess more than 1000. Fascinating features of the vertebrate olfactory system include allelic exclusion, where each olfactory neuron expresses only a single OR gene, and axonal guidance where neurons expressing the same receptor project axons to common glomerulae. By identifying homologous ORs in vertebrate and in non-vertebrate chordates, we hope to expose ancestral features of the chordate olfactory system that will help us to better understand the evolution of the receptors themselves and

Phylum Chordata includes the vertebrates. Although not as common as the invertebrates, teeth and bones from different classes of vertebrate animals can be found at Canal sites.
The most complex group of animals to exist are the Chordates; comprising of all vertebrates and some invertebrates the Chordates all share and experience certain characteristics at some stage in their development.. These characteristics are what defines the chordates as complex animals. A notochord, the cartilage between the nerve chord and the spinal cord is only present in chordates. The dorsal hollow nerve chord will eventually develop into the central nervous system. Pharyngeal slits are gill like structures, we lose these before leaving the womb but some chordates keep them their whole lives. the final characteristic that defines and organism as part of the phyla chordata is a post anal tail. In humans, this is our coccyx.. Contain all of these characteristics and its safe to say youre a complex Chordate.. From Crash Course: Biology on YouTube presented by Hank Green. ...

Austroblechnum lanceolatum and A. norfolkianum are a species pair that need further taxonomic investigation. Exact distinctions between these species are difficult. Chambers & Farrant (1998) suggest that this is due to hybridisim but the basis for that suggestion is not clear. Most field botanists distinguish these two species on the basis of distribution and ecology with A. norfolkianum known only from northern New Zealand where it is mostly found on offshore islands. In this area it is typically found on rodent-free, sea bird islands where it is a conspicuous member of the shaded forest floor of petrel colonies as well as the more usual shaded bank and cliff habitats. Austroblechnum norfolkianum usually has brighter green, succulent fronds without the darker pink or maroon pigmentation often seen in A. lanceolatum, and the pinna of A. norfolkianum are consistently falcate (those of A.lanceolatum less often so), while the fertile fronds of A. norfolkianum are said to be shorter than sterile ...

A chordate is an animal belonging to the phylum Chordata; chordates possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle. Chordates are deuterostomes, as during the embryo development stage the anus...
The notochord is an elongate, rod-like, skeletal structure dorsal to the gut tube and ventral to the nerve cord. The notochord should not be confused with the backbone or vertebral column of most adult vertebrates. The notochord appears early in embryogeny and plays an important role in promoting or organizing the embryonic development of nearby structures. In most adult chordates the notochord disappears or becomes highly modified. In some non-vertebrate chordates and fishes the notochord persists as a laterally flexible but incompressible skeletal rod that prevents telescopic collapse of the body during swimming. The nerve cord of chordates develops dorsally in the body as a hollow tube above the notochord. In most species it differentiates in embryogeny into the brain anteriorly and spinal cord that runs through the trunk and tail. Together the brain and spinal cord are the central nervous system to which peripheral sensory and motor nerves connect. The visceral (also called pharyngeal or ...

Using sequence homology with experimentally known amphioxus mature miRNAs, a total of 155 candidate miRNAs with 71 miRNA-stars was identified from the amphioxus B. belcheri genome (Supplemental Table I). Among the 57 novel bbe-miRNAs, 55 were identical to bfl-miRNAs from B. floridae and 2 were homologous to bja-miRNAs from B. japonicum. Of the 155 mature bbe-miRNAs, 108 were amphioxus specific. To further determine whether these candidate miRNAs were genuine miRNAs, the pre-miRNA sequences downloaded were used to scan the amphioxus B. belcheri genome for stem-loop structures for the candidate miRNAs. In total, 124 loci with typical hairpin structures were generated (Supplemental Table I). These loci were considered candidate miRNA genes and were coding for 112 mature miRNAs and 68 miRNA-stars. Forty-three other mature miRNAs and their pre-miRNAs were not identified in the amphioxus B. belcheri genome; a possible explanation is this genome is not sequenced completely. For example, all of the ...

Passerines (phylum Chordata, subphylum Vertebrata, superclass Tetrapoda, class Aves, order Passeriformes), sometimes called perching birds, are birds adapted to hold on to a perch tightly, even when they are asleep. Three of their four toes are oriented forward, and the remaining one is oriented backwards. All the toes can move independently of each other, with the back toe being exceptionally strong. And when a passerine lands on a perch, its weight causes the tendons in the leg to tighten and the toes will clamp together tightly, allowing the bird to have a tight grip on the perch ...
The ParaHox gene cluster is an array of homeobox genes (involved in morphogenesis, the regulation of patterns of anatomical development) from the Gsx, Xlox (Pdx) and Cdx gene families. These genes were first shown to be arranged into a physically-linked chromosomal cluster in amphioxus, an invertebrate with a single member of each of the three gene families. All the ParaHox genes in the amphioxus genome are therefore in the ParaHox gene cluster. In contrast, the human genome has six ParaHox genes (GSX1, GSX2, PDX1, CDX1, CDX2, CDX4), of which three genes (GSX1, PDX1 (=IPF1), CDX2) are physically linked to form a human ParaHox gene cluster on chromosome 13. Mouse has a homologous ParaHox gene cluster on chromosome 5. The other three human ParaHox genes are remnants from duplicated ParaHox gene clusters that were generated in the 2R genome duplications at the base of vertebrate evolution. Some vertebrates, notably chondrichthyan fish and coelacanths, have retained an additional ParaHox gene ...

The guidelines identify key indicators for the identification of demographic issues in coastal area management and for monitoring the impact of management measures on the socio-economic well-being of coastal and fishing communities. The guidelines also identify data sources and methods for the collection of data. Case studies on the use of demographic data in coastal area management in Italy and the USA and a summary of the proceedings of a regional workshop on the use of demographic data in coastal area management in the Philippines and other Southeast and South Asian Countries provide practical examples as to how demographic indicators are actually used.

Interleukin-17 receptor (IL-17R) is a cytokine receptor which binds interleukin 17A. Functional IL-17R is a heteromeric complex consisting of at least IL17RA and IL17RC. A number of additional variants exist including IL17RB, which binds preferentially IL17B and IL17E. A total of five members of the family have been identified. The first identified member, IL-17RA is located on human chromosome 22. There are two IL17Rs (IL17RA and IL17RD) in the genome of the basal chordate Amphioxus. After two rounds of whole genome duplications, these two IL17R genes expanded into five early vertebrate IL17R genes, IL17RA to IL17RE. Two (IL17RA and IL17RD) are found in most vertebrates, whereas the other three (IL17RB, ILR17RC and IL17RE) have undergone some losses in vertebrates during evolution. IL-17RA is the founding member of a new IL-17R(A-E) subfamily of cytokine receptors. IL-17RA is by far the largest member of the family and has the largest cytoplasmic tail of the family. This cytoplasmic tail ...

The origin and affinities of chordates and echinoderms have long been a subject of interesting speculation. Relationships between creatures are postulated..
JUNEAU, Alaska (AP) - A resolution aimed at promoting inclusivity in a small Alaska fishing community has been rejected after it proved too divisive.
Dipleurula definition is - a hypothetical bilaterally symmetrical echinoderm larva sometimes regarded as a common ancestor of echinoderms and chordates.

Several Nobel Prize awards correlated with fluorescence. It is a long tradition that many Embyologists (Developmental Biologists) concentrated their interest in marine research. The term ecology was coined very late around 1960. Aspects of ecology and environmental protection (also sustainability) were unknown in the 19. and early 20. century. This is easy to understand, since environmental problems were unknown at thistime. Famous zoologist, especially developmental biologists (mainly Germans) worked at the well known marine station (Anton Dohrn) in Naples and other reserch stations, Sea urchin and lancelet fish Branchiostoma lanceolatum were favored objects for embryological studies.. It is not arrogant to say that still to day the early development of organisms is a cental topic in biology. The individual development (ontogenesis) is the most sensitive period of all organisms. The Contergan disaster during human embryogenesis is a terrible example. As we now know the adult organism is much ...

Appendicularians are pelagic tunicates that remain free-swimming throughout life, in contrast sessile tunicates, witch are only free-swimming as larvae. Urochordates in general are receiving increasing focus in the context of vertebrate brain evolution, since they derive from the base of the chordate linage tree. In this project, "the mapping of the nervous system of Oikopleura dioica", the development of the neurons in the major components of the nervous system is addressed. The development of the caudal nerve cord of the appendicularian Oikopleura dioica was assessed using differential interference contrast and confocal microscopy, phalloidin staining of actin, and in situ hybridization for the neuronal markers α-tubulin and choline acetyltransferase (ChAT). The caudal nerve cord first appears as a stream of α-tubulin mRNA-positive neurons that can be seen extending into the tail from the caudal ganglion as early as 4 hours after fertilization. Already at this stage a few actin-rich nerve ...
The packaging of DNA into nucleosomes is a fundamentally conserved property of the eukaryotic nucleus which is evident in the conservation of histone sequences. Nevertheless, it is now clear that histone sequence variants have diversified in many species to assume crucial roles in the regulation of gene expression, DNA repair, chromosome segregation and other processes. While considerable data exist on coding sequences of histones and some selected histone variants in a wide variety of organisms, the information available on total histone gene complements is much more limited. Oikopleura dioica (Od) is a dioecious marine urochordate that occupies a key phylogenetic position near the invertebrate-vertebrate transition with the smallest genome ever found in a chordate (70 Mb). Its short life cycle is characterized by a developmental switch between mitotic and endocycling cells, making O. dioica an attractive model to study the spatial and temporal use of histone variants and posttranslational ...
My research focuses on understanding the evolutionary origins of complex traits within the vertebrate head. Such complex traits include an elaborated ventricular brain, neural crest and placodal derivatives, and the development of craniofacial structures. Because of their absence outside the vertebrate subphylum, they are generally regarded as vertebrate innovations, thus closely linked to the invertebrate-vertebrate transition. My main objective is to decipher the molecular changes that underlie the emergence of such morphological innovations, which likely facilitated the evolution and radiation of vertebrates on earth. To do this, I use the pre-vertebrate amphioxus (cephalochordate) as a model system, since it is currently regarded as the best extant proxy to the ancestral chordate that gave rise to all vertebrates.. ...

Cephalochordates (subphylum Cephalochordata) are commonly referred to as lancelets or amphioxus. They appear fish-like, but unlike fishes they lack paired fins and only has a very poorly developed tail fin. Their nerve cord is within a simple notochord made up of tightly packed cells. They have no eyes, and use tentacle-like structures in front of the mouth to sense their surroundings and filter suspended food particles such as plankton from the water. They breathe through their skin, and hide in the sediment most of the time, though some of the specimens recorded from Singapore were caught with nets near the surface of the water. They are harvested and consumed in the region. The above photo features an unidentified museum specimen caught from the South China Sea ...
Kingdom: Animalia. Phylum: Chordata. Class: Actinopterygii. Order: Batrachoidiformes. Family: Batrachoididae. This fish is the plainfin midshipman (Porichthys notatus). If you were looking at the top of the fish, you would see a plain grayish fish with a rather large mouth. One of the midshipmans interesting features actually lie underneath the fish. These interesting dots on the underside of the fish are photophores, which can produce a bright light pattern. Its still not clear what the light is for, but some speculate that the midshipman uses them to lure prey closer when hunting. The midshipman will hang in the water column and flash its light to attract prey items.. Interesting thing number 2 is how midshipman reproduce. Like most fish, males are responsible for maintaining the nest and attracting the females to lay their eggs. Male midshipman will hum for hours on end to attract females to their nest. The hum is produced by the fish vibrating their swim bladder, and can be so loud that ...

Retinoic acid (RA)-mediated expression of the homeobox gene Hox1 is a hallmark of the chordate central nervous system (CNS). It has been suggested that the RA-Hox1 network also functions in the epidermal ectoderm of chordates. Here, we show that in the urochordate ascidian Ciona intestinalis, RA-Hox1 in the epidermal ectoderm is necessary for formation of the atrial siphon placode (ASP), a structure homologous to the vertebrate otic placode. Loss of Hox1 function resulted in loss of the ASP, which could be rescued by expressing Hox1 in the epidermis. As previous studies showed that RA directly upregulates Hox1 in the epidermis of Ciona larvae, we also examined the role of RA in ASP formation. We showed that abolishment of RA resulted in loss of the ASP, which could be rescued by forced expression of Hox1 in the epidermis.

There are many competing hypotheses for the form of the evolutionary tree of animals. A traditional hypothesis is that the tree resembles a tuning fork: it has a short base and two main branches. However, there is recent molecular evidence that challenges part of this traditional hypothesis. Under the tuning fork model, the "base" of the tree includes structurally simple animals like sponges, corals, and their relatives. One main branch includes arthropods, molluscs, annelids, and nematodes. This branch, or a large part of it, usually is called the protostomes. The second main branch includes vertebrates (phylum Chordata), and starfish, sea urchins, and their relatives (phylum Echinodermata). This branch usually is called the deuterostomes. Flatworms (phylum Platyhelminthes), which include free living planarians as well as parasitic flukes and tapeworms may be placed very low on the protostome branch, or high on the trunk just below the protostome - deuterostome branching. ...

Gene duplication has been proposed to drive the evolution of novel morphologies. After gene duplication, it is unclear whether changes in the resulting paralogs coding-regions, or in their cis-regulatory elements, contribute most significantly to the assembly of novel gene regulatory networks. The Transcription Factor Activator Protein 2 (Tfap2) was duplicated in the chordate lineage and is essential for development of the neural crest, a tissue that emerged with vertebrates. Using a tfap2-depleted zebrafish background, we test the ability of available gnathostome, agnathan, cephalochordate and insect tfap2 paralogs to drive neural crest development. With the exception of tfap2d (lamprey and zebrafish), all are able to do so. Together with expression analyses, these results indicate that sub-functionalization has occurred among Tfap2 paralogs, but that neo-functionalization of the Tfap2 protein did not drive the emergence of the neural crest. We investigate whether acquisition of novel target ...
