Codium illustrates a diplontic life cycle where gametes are the only haploid structures. 3.1E). atlanticum is known to have arrived in the southwest of Ireland around 1808. These calcified green and red seaweeds play an important role in the calcium cycle of the ocean. known in C. fragile and its subspecies (reviewed in Trowbridge 1998). The segments look like dark green fingers. Accordingly, this needs to be confirmed further through more in-depth biochemical studies under controlled laboratory conditions. Codium cell wall polysaccharides, eg, sulfated galactans, sulfated arabinans, mannans, and hydroxyproline-rich glycoproteins, result in distinct structural features, several of them exhibiting biological activities with pharmaceutical applications, eg, anticoagulants, antiangiogenics, antivirals, and immunostimulants (FernÃ¡ndez etÂ al., 2014). Although ascorbic acid is usually destroyed by drying, coastal populations still derive significant quantities of the vitamin from eating the fresh algae (MacArtain etÂ al., 2007; CreacâH and Baraud, 1954). The cytoplasm of Caulerpa contains a specific wound-healing compound known as caulerpenyne. Sulfated heterofucans from C. cervicornis prolonged activated partial thromboplastin time, exhibiting an anticoagulation effect that was only 1.25-fold less than Clexane (Camara etÂ al., 2011). On the other hand, Codium species are used as food for cultured abalone, they are consumed by humans, and they are a source of bioactive compounds (Verbruggen etÂ al., 2007). It is a dark fairly large green seaweed, which grows on hard surfaces at â¦ The development of Caulerpa has not been followed beyond the zygote formation. Surveys were conducted at 2 sites in the San Lorenzo Channel at depths of 8 - 12 m. Comprehensive analysis of the structural polysaccharides and their arrangement in the cell walls was used as a base for detailed description of the unique cell wall architecture of the Codium species (Estevez et al., 2009). Codium fragile (Suhr) Hariot. Septate thalli in this order can be only seen during the reproductive stages. According to Hanisak , seasonal growth of C. fragile ssp. Table 2.4. ), Hypoglossum tenuifolium, Kuckuckia kylinii, Protectocarpus speciosus, Porphyra leucosticta, P. rizzini, Hecatonema terminalis, Gelidiocolax pustulata, and Gonimophyllum africanum on Cryptopleura ramosa) are small epiphytes on Pterocladia capillacea, an abundant alga characteristic of high wave exposure. The predominant seaweeds observed are Enteromorpha, Ulva, Codium, Laminaria, Turbinaria, Sargassum, Padina, Geldium, Gracilaria, Hypena and Ceramium. About dead man's fingers. Thus, gametophyte microthalli of Derbesia sps. Fig. Until the present century, the only detailed structural studies of sulphated polysaccharides from this order were those of Percival and coworkers (Percival & McDowell, 1981), including those carried out on the polysaccharides from C. fragile (Love & Percival, 1964a).  It has also been recorded from the Scilly Isles, the Channel Islands, and the south and west coasts of England and Scotland. Fucoidan has been compared to animal-derived anticoagulant heparin (Patel, 2012). Experiments were carried out on the changes in weight, chlorophyll content and photo-synthetic capacity of Elysia viridis over periods of up to 8 weeks when incubated in light or dark, with and without its source of chloroplasts, the seaweed Codium fragile. Codium and Caulerpa are two important members of this order and belong to the Codiaceae and Caulerpaceae families, respectively. The life cycle of Codium fragile shows strong seasonal trends with respect to frond morphology and chloroplast physiology. It forms long erect finger-like fronds. NMR spectra revealed that the branched fucoidan oligosaccharides display a better anticomplementary activity compared to linear structures (Clement etÂ al., 2010). Codium is found in marine habitats ranging from rocky coasts exposed to full wave-forces to calm lagoons, from intertidal habitats to deep reefs, from arctic to tropical waters and from eutrophic estuaries to nutrient-depleted coral reefs (Verbruggen etÂ al., 2007). atlanticum by its very pointed mucron (the tip of the urticle) – up to µm 68 long. Codium fragile occurs in the low intertidal zone, and subtidal on high-energy beaches. It originates in the Pacific Ocean near Japan and has become an invasive species on the coasts of the Northern Atlantic Ocean. Seema Patel, in Bioactive Seaweeds for Food Applications, 2018. f-h) once erect thalli develop, the fibers are coiled around a larger culture rope. Caulerpa, Dictyota and Laurencia can be used as food in different forms. Very interesting data were obtained on the direct interaction of a sulfated arabinan from C. vermilara with thrombin and on the dependence of anticoagulant activity of the polysaccharide on the position of sulfate groups (FernÃ¡ndez et al., 2013). As expected, green macroalgae also emerged as novel antiviral agents. A highly-sulfated galactan from red algae Lomentaria catenata demonstrated anticoagulation efficacy better than heparin (Pushpamali etÂ al., 2008). Ayyam Velmurugan, ... John Mathai, in Biodiversity and Climate Change Adaptation in Tropical Islands, 2008. On view at the Aquarium in Rocky Shore. The spring and autumn harvests are highest in vitamin C content. I. Levine, in Seaweed in Health and Disease Prevention, 2016. The third ordination axis could be interpreted as a factor describing substrate occupation and epiphytism. A highly ramified molecules built up of 3- and 3,6-linked Î²-D-galactose residues were shown to carry sulfate mainly at C-4, but also at C-6, whereas pyruvate residues form five-membered ketals with O-3 and O-4 of non-reducing terminal galactose residues. P. 202. Codium edule; Codium foveolatum Howe; Codium fragile (Suringar) Hariot; Codium geppii Schmidt; Codium hubbsii Dawson, 1950; Codium intertextum; Codium isthmocladum Vickers, 1905; Codium johnstonei Silva; Codium mamillosum Harv. Altogether 114 species under 62 genera of seaweeds were recorded from Lakshadweep (Kaliaperumal etÂ al.,Â 1989). It was concluded that photosynthesis is of considerable importance in the nutrition of the animal. Daniel G. VassÃ£oKye-Won KimLaurence B. DavinNorman G. Lewis, in Comprehensive Natural Products II, 2010, Sporadic, albeit somewhat preliminary, reports have been made of allyl-/propenylphenol occurrence in brown (Spatoglossum variabile),29 red (Jania rubens30 and Hypnea musciformis31), as well as green (Enteromorpha compressa,31 Caulerpa racemosa,32 and Codium tomentosum32) algae. ... etc. The complete plant body can be divided in two parts: (1) a rhizome with root-like achlorophyllous rhizoids and (2) an erect shoot. Populations of this algae occur mostly in northern Britain. Caulerpa is the lone genus of the family Caulerpaceae. It is estimated that the agarophyte resource with an abundance of Gelidiella acerosa can be utilised for starting an agar-agar unit. Figure 9.1.

In prothrombin test, D. cervicornis SP prolonged the coagulation time only a 1.4-fold lesser than Clexane, a low-molecular weight commercial heparin (Costa etÂ al., 2010). Codium fragile subsp.  The "fingers" are branches up to a centimeter wide and sometimes over 30 centimeters long. Larval metamorphosis in E. viridis was greatest on potential host species, but larvae also responded to nonhost macrophytes and adult conspecifics. The orientals prefer Porphyra, Gracilaria, and Eucheuma; the occidentals have Palmaria or âDulse,â Chondrus or âIrish Moss,â and Porphyra or âLaver,â to cite the more popular ones. Variation in C. fragile frond morphology can be divided into two distinct seasonal phases, namely the winter/spring and sÛmmer/autumn periods. The predominant seaweeds observed are Enteromorpha, Ulva, Natural Products Structural Diversity-I Secondary Metabolites: Organization and Biosynthesis, Daniel G. VassÃ£oKye-Won KimLaurence B. DavinNorman G. Lewis, in, Macroalgae of the Cabo Frio Upwelling Region, Brazil: Ordination of Communities, Y. Yoneshigue-Valentin, J.L. A SP from brown seaweed E. cava also exhibited anticoagulant activity both inÂ vitro and inÂ vivo (Wijesinghe and Jeon, 2012). Moreover, cellulose was found to be a minor fibrillar component of the cell walls from Bryopsis maxima and Bryopsis plumosa (Ciancia etÂ al., 2012; Fukushi etÂ al., 1988; Maeda etÂ al., 1990). Rajapakse and others confirmed the richness of seaweed in some health-promoting molecules such as essential amino acids, vitamins A, B, C, and E, and iodine (Yeh etÂ al., 2014; Rajapakse and Kim, 2011; Dhargalkar and Pereira, 2005). A sulfated rhamnan polysaccharide from the green alga Monostroma latissimum exhibits anticoagulant activity (Li etÂ al., 2011). It is thought to have originally come from the Pacific Ocean near Japan. On the other hand, seaweeds of the Bryopsidales (Chlorophyta) belong to the second group, and only small to trace amounts of uronic acids and rhamnose, if any, were detected in the polysaccharides. Not known how it came to Canada, best guess is from bottom of hulls on ships.  The fronds hang down from rocks during low tide, hence the nickname "dead man's fingers". Caulerpa is also known as a rapidly growing aggressive seaweed because of a unique asexual mode of reproduction, which can be considered as vegetative reproduction. , This subspecies was introduced from Asiatic coasts of the Pacific to Norway, and to Denmark in 1919. Its holdfast is a broad, spongelike cushion of tissue. Among its epiphytes Spiny straggle weed Gelidium spinosum (ID thanks to Seaweeds of the Atlantic facebook page members) which is also freeliving, and finally the green Codium fragile. The highest iodine content is found in brown algae, with dry Laminaria ranging from 1500 to 8000Â ppm and dry Fucus from 500 to 1000Â ppm (Yeh etÂ al., 2014; Dharmananda, 2002). It was observed that anticoagulant activity was higher in SP samples with higher sulfate content. In Codium, zygotes immediately germinate and give rise to a new thallus. Main reference References | Coordinator | Collaborators. tomentosoides is an alga that has been introduced around the globe through shellfish aquaculture, recreational boating, and transport on ship hulls. , This subspecies is found in the low intertidal to subtidal zones around New Zealand at the North Island, South Island, Chatham Islands, Stewart Island, Auckland Island, Campbell Island as well as around the Falkland Islands.. In addition, there is also information available about the fibrillar components of the cell walls of the Bryopsidales. Figure 2.6. Also known widely in the literature as Codium fragile subsp. It has no asexual (sporophyte) stage, and male and female gametes are both produced on separate plants. are among the favored ones. The utricles occur in a wide array of forms, varying in size, shape and composition, with gametangia and/or hairs borne along their sides (Figure 9.1). In culture experiments, higher growth rates of this Codium species were observed at 18 and 24 °C under long-day photoperiods (Hanisak 1979). Generally, seaweed collected from littoral zones is richer in vitamin C than that obtained from deeper waters. Members of this group show a wide range of thallus organization and form. A sulfated Î²-D-mannan from green seaweed C. vermilara had anticoagulation effect, which was improved when the sulfate content was higher (FernÃ¡ndez etÂ al., 2012). Brown (1953) noted the presence of Î´-tocopherol in seaweed. These protein- and iodine-rich marine plants, found in both cold and warm seas, have been known for their contemporary food preparations as salad, soup, pickles, jam, etc. On Pterocladia (site 2), epiphytes are small tufts with erect filaments firmly attached to the host, which allows them to resist local hydrodynamic conditions. 2003. Cellulose is normally replaced by Î²-1,3-linked xylan or a Î²-1,4-linked mannan (Lee, 2008). It is a rapidly spreading invasive species. 3.3). Valentin, in, Coastal Plant Communities of Latin America, Journal of Experimental Marine Biology and Ecology. In 1952, Ericson (1952) reported the presence of vitamin B12, folic acid, in various brown and red seaweeds from the Baltic and North Seas, with content values comparable to that in liver. Likewise, sulfated polysaccharide fraction isolated from the hot water extract of the green alga Caulerpa racemosa was regarded as a selective inhibitor of reference strains and TKâ acyclovir-resistant strains of HSV-1 and HSV-2 in Vero cells, with EC50 values in the range of 2.2â4.2 Î¼g/ml (Ghosh et al., 2004). For example, sporophyte macrothalli of Derbesia and microthalli of Bryopsis produce mannans, while gametophyte microthalli of the same species of Derbesia and macrothalli of Bryopsis biosynthesize xylans. They are similar, both are dark green in color. Codium divaricatum Gepp. The positions of discoid chloroplast and small nuclei are peripheral and interior, respectively. fragile is a large branching green alga which typically grows between 15 to 60 cm tall but can attain almost 1 m in length and weigh up to 3.5 kg. The reported occurrence of very small amounts of apiol (36) and nothoapiol (40) in the brown alga (S. variabile)29 growing on shoreline sublittoral rock near Karachi, Pakistan, would benefit from additional biochemical proof, preferably through the analysis of this alga grown under controlled laboratory growth conditions. Under nitrogen deficiency some species of Codium such as Codium fragile can fix atmospheric nitrogen-like Azotobacter bacteria (Head and Carpenter, 1975). This species displaces the native Codium tomentosum. These sulphated polysaccharides in high ionic strength media such as seawater would remain strongly charged providing mechanical stress resistance, hydration by gel formation, and they would act as ionic and osmotic regulators (Kloareg & Quatrano, 1988). Codium fragile (Suringar) Hariot sponge seaweed Upload your photos Google image | No photo available for this species.  The rounded tips of these closely packed utricles give the frond a velvety texture. Codium fragile, an invasive seaweed, has spread widely during the last century, impacting on local seaweed communities through competition and disturbance.Early detection of C. fragile can help on its control and management. The period of maximum carbon fixation, pigment content and chloroplast size occurs during the early winter when competition from other algae is small and the variation in tidal amplitude decreased. Halimeda is another important member of the family Codiaceae. , The subspecies Codium fragile subsp. (2004b) have estimated anti-HSV-1 activity of natural sulfated polysaccharides from 10 green macroalgae (Enteromorpha compressa, Monostroma nitidum, Caulerpa brachypus, Caulerpa okamurai, Caulerpa scapelliformis, Chaetomorpha crassa, Chaetomorpha spiralis, Codium adhaerens, Codium fragille, and Codium latum). In the delineation of the drug-sensitive phase, the polysaccharides of SX4 and SP4 from C. brachypus and SP11 from C. latum showed potent anti-HSV-1 activities with IC50 values of 6.0, 7.5, and 6.9 Î¼g/ml, respectively, even when added to the medium 8 h postinfection. SP from the brown seaweed L. saccharina was protective from thrombosis (Croci etÂ al., 2011). Since 1840, when it was first discovered in Scotland, it has spread the entire length of Britain, including Shetland. This seaweed mainly occurs in tropical and semitropical regions of the world. In this subspecies the mucron is short, no more than 20 µm long.. Interestingly, female gametangia have a dark green color whereas male gametangia have a brown color. Codium fragile subsp. Authors and editors of page Chanda Brietzke, Kelly Fretwell, and Brian Starzomski (2016). (A) General aspect of the Thallus of Codium vermilara. As this calcification of plant usually occur outer portion it also help in fossil formation. Codium fragile occurs in the low intertidal zone, and subtidal on high-energy beaches. They inhibited thrombin and coagulation factor Xa by potentiating antithrombin III (Mao etÂ al., 2008). Species with coordinates close to site 2 on axis III (Callophyllis microdonta, Neuroglossum binderianum (? Some people add slices of green unripe mango and crushed tomatoes to enhance the salad preparation. In addition, it has been shown that the major fibrillar component of the cell wall can vary in the different life stages (Huizing & Rietema, 1975; Huizing, Rietema, & Sietsma, 1979; Wutz & Zetsche, 1976). Paula Virginia FernÃ¡ndez, ... Marina Ciancia, in Advances in Botanical Research, 2014. The content and structures of water-soluble sulfated polysaccharides were carefully investigated in the representatives of the genus Codium. Copyright Â© 2020 Elsevier B.V. or its licensors or contributors. The dark, spongy "fingers" of this seaweed dangle from the tops and sides of rocks. Codium fragile subsp. Species of Caulerpa and Codium, known in the Philippines as âlatoâ (Visayan) and âpok-pokloâ (Ilokano), respectively, are the most common edible green algae among the South-east Asians. The cortex of the branches is formed by closely packed utricles, these are small cylindrical club-shaped structures formed from a single cell up to 1200 µm (micrometre) long. This species also causes a nuisance to humans when it accumulates on beaches and rots producing a foul odor. Anticoagulant properties of seaweed-derived SP have been verified in this regard. This subspecies can be distinguished by the mucron or tip of the utricles. It was observed that anticoagulant activity was higher in SP samples with higher sulfate content. Similar sulfated galactans were also isolated from Codium fragile (Ciancia et al., 2007; Ohta et al., 2009), C. vermilara (Ciancia et al., 2007) and C. isthmocladum (Farias et al., 2008), although the latter polysaccharide contains essentially linear 4-sulfated 3-linked molecules, whereas the former two polysaccharides may really be arabinogalactans having the arabinan part constituted by 3-linked arabinopyranose residues sulfated on C-2 or C-4. A highly sulfated and pyruvylated galactan was isolated from the aqueous extract of Codium yezoense (Bilan et al., 2006b). (C) General aspect of the dry thallus of Codium fragile. The phytochemistry of the genera was largely reviewed by Liu etÂ al. Codium exhibits many adaptations to its habit, changing its number and size of chloroplasts, pigment content, development of frond hairs, etc. fragile (Suringar) Hariot, 1889, e os macro-invertebrados Microscosmus squamiger, Michaelsen, 1927, Bugula neritina L., 1758, Tricellaria inopinata dâHondt e Occhipinti-Ambrogi, 1985 e Zoobotryon verticillatum Delle P.A.
