chilena gracilaria chilensis: Topics by
Gracilaria chilensis Gracilariales, Rhodophyta. Se compara este proceso con el descrito en otras especies de la clase. The history of a domesticated marine macroalga is studied using archaeological, phylogeographic and population genetic tools. Phylogeographic and population genetic analyses demonstrated that the cultivated red alga Gracilaria chilensis colonised the Chilean coast from New Zealand.
Combining archaeological observations with phylogeographic data provided evidence that exchanges gasgos New Zealand and Chile have occurred at least before the Holocene, likely at the end of the Last Glacial Maximum LGM and we suggest that migration probably occurred via rafting. Therefore, the aquaculture of this seaweed, based essentially on clonal propagation, is occurring from genetically depressed populations and may be driving the species to an extinction vortex in Chile.
Molecular and functional characterization of ferredoxin NADP H oxidoreductase from Gracilaria chilensis and its complex with ferredoxin. Methods Declaracikn biochemical and kinetic characterization of FNR was performed from the enzyme purified from phycobilisomes enriched fractions. The sequence of the gene that gstos for the enzyme, was obtained using primers designed by comparison with sequences of Synechocystis and Declarracion from Gracilaria. The sequence for FNR was obtained and translated to a protein of Da.
Phycobilisome binding domain, present in some cyanobacteria was absent. Conclusion The interaction model produced, was consistent with functional properties reported for FNR in plants leaves, and opens the possibilities for research in other rhodophyta of commercial interest.
Full Text Available The current study examined the nutrient uptake efficiency of Ulva lactuca and Gracilaria chilensis cultivated in tanks associated with the wastewater of a land-based abalone culture. The experiments evaluated different seaweed stocking densities,and g m-2 and water exchange rates 60, 80,and L h The results show that both U. Furthermore, an annual experiment was performed with U. The growth rate and productivity of U. We conclude that there is sufficient evidence gastox demonstrates the high possibility of changing the traditional monoculture system of abalone in Chile, to a sustainable integrated multi-trophic aquaculture system, generating positive environmental mensyales, including the use of U.
Structural models of the different trimers present in the core of phycobilisomes from Gracilaria chilensis based on crystal structures and sequences. Full Text Available Phycobilisomes PBS are accessory light harvesting declaeacion complexes that directionally transfer energy towards photosystems. Phycobilisomes are organized in a central core and rods radiating from it.
The gastoa of such complexes gashos on the structure of each component declarracion their interaction. Since we have previously focused our studies on the rods of the PBS, in the present article we investigated the components of the core in the phycobilisome from the eukaryotic algae, Gracilaria chilensis and their organization mensuaales trimers.
Transmission electron microscopy provided the information for a three cylinders core, while the three dimensional structure of Allophycocyanin purified from Gch was determined by X-ray diffraction method and the biological unit was determined as a trimer by size exclusion chromatography.
The protein sequences of all the components of the core were obtained by sequencing the corresponding genes and their expression confirmed by transcriptomic analysis. These subunits have seldom been reported in red algae, but not in Gracilaria chilensis.
The subunits not present in the crystallographic structure were modeled to build the different composition of trimers. This article proposes structural models for the different types of trimers present in the core of phycobilisomes of Gch as a first step towards the final model for energy transfer in this system.

Observaciones sobre el comportamiento de Schroederichthys chilensis Carcharhiniformes, Scyliorhinidae. Schroederichthys chilensisthe redspotted catshark or chilean catshark, is gstos endemic species to Peruvian and Chilean waters.
This hypothesized survival strategy has not been previously documented in this species and we recommend further studies to elucidate this behavior. New Microsatellite Loci for Prosopis alba and P.
Full Text Available Premise of the study: As only six useful microsatellite loci that exhibit broad cross-amplification are so far available for Prosopis species, it is necessary to develop a larger number of codominant markers for population genetic studies. Simple sequence repeat SSR markers obtained for Prosopis species from a pyrosequencing run were optimized and characterized for studies in P. Twelve markers that were successfully amplified showed polymorphism in P.
The number of alleles per locus ranged between fastos and seven and heterozygosity estimates ranged from 0. Most of these loci cross-amplify in P. These loci will enable genetic diversity studies of P. New microsatellite loci for Prosopis alba and P. Marine biomass research in Florida.
The red alga Gracilaria tikvahiae may be grown outdoors year-round in central Florida with yields averaging This occurs when the plants are grown in suspended culture, with vigorous aeration and an exchange of 25 or more culture volumes of enriched seawater per day. The biomass is soaked for 6 hours in the digester residue, storing enough nutrients for two week’s growth in unenriched seawater.
It can therefore produce higher yields than Mensulaes in low water exchange conditions. It is also more efficiently converted to methane than is Gracilariabut cannot tolerate Florida’s summer temperatures so cannot be grown year-round.
Attempts are being made to locate or produce through selective breeding, a high-temperature tolerant strain of Ulva. Las franjas electorales en la experiencia chilena.
Native agar gels extracted from Gracilaria debilis and G. Declaracionn extracted from plants harvested during the rainy season were suitable for culturing Observations on the behavior of Schroederichthys chilensis Carcharhiniformes, Scyliorhinidae.
Full Text Available Schroederichthys chilensisthe redspotted catshark or chilean catshark, is an endemic species to Peruvian and Chilean waters. Working in the context of language studies, we adopt a route of discursive description and interpretation of this relationship, which highlights aspects of literary, ociopolitical and cultural memories. For this, we will use the notions of dialogism Bakhtin and memory Charaudeau, highlighting its three dimensions — the memory of signs, the memory of situations and the memory of discourse.
Thus, the relationship between mnemonic in these works contributes to the design the persuasive project of Valadares. Cultivation and conversion of marine macroalgae. Research was conducted on the development of an alternative ocean energy farm concept that would not be dependent upon deep ocean water or other extraneous sources for its nutrient supply and that could be located in shallow, near shore, and protected coastal ocean areas.
There are five tasks reported in this document: An alternative concept to open ocean culture is a land-based energy production system utilizing saline waters from underground aquifers or enclosed coastal areas.
Research was performed to evaluate growth and biomass production of all macroscopic algal species that could be obtained in adequate quantity in the central Florida area.
A total of 42 species were grown in specially adapted burial vaults. These included 16 green algae Garcilaria 4 weekshlorophyta2 brown algae Phaeophytaand 18 red algae Rhodophyta. Of these, the most successful and suitable species were a strain of Gracilaria a red seaweed and Ulva a green seaweed.
These two species have a high carbohydrate content that may be anaerobically digested to methane gas. Well-nourished Gracilaria will double its biomass in 1 to 4 weeks, depending on the season, water flow, and other variables. After its biomass has doubled i.
Enrichment of the new starting crop following harvest could conceivably be accomplished onsite at the seaweed farm, but the rapid uptake and storage of nutrients by depleted seaweeds makes possible a simpler process, known as pulse fertilization. Field studies on the photosynthesis of two desert Chilean plants: Prosopis chilensis and Prosopis tamarugo. The objective of this work was to compare the photosynthetic responses and to determine the degree of adaptation of both species to visible- and UV-radiation stress.
One of the study sites was Refresco in the Atacama Desert, where P. The parameters investigated in both species were photosystem II fluorescence, CO 2 assimilation, stomatal conductance, photosynthetic pigment composition, flavonoid absorption patterns and composition of chlorophyll-protein complexes.
