Subject:
Microcystis aeruginosa; algae; algology; cobalt; freshwater; phosphorus; surveys; vitamin B12; Australia
Abstract:
... Micronutrients play key roles in numerous metabolic processes in cyanobacteria. However, our understanding of whether the micronutrient cobalt influences the productivity of freshwater systems or the occurrence of cyanobacterial blooms is limited. This study aimed to quantify the concentration of Co necessary for optimal cyanobacterial growth by exposing Microcystis aeruginosa to a range of Co con ...

Abstract:
... Mixotrophs are increasingly recognized for their wide distribution in aquatic ecosystems and significant contributions to biogeochemical cycling. Many taxa within the phyla Chrysophyta, Cryptophyta, and Haptophyta are capable of phago‐mixotrophy, however, phagotrophy in the Chlorophyta remains controversial due to insufficient research and solid evidence. In this study, we identified a new strain, ...

Abstract:
... The MYB transcription factor (TF) family is one of the largest and most important TF families, regulating the growth and response of microalgae to stress. However, the gene structure and characteristics of Phaeodactylum tricornutum MYB TFs, and their functions under nitrogen deficiency, have not been explored yet. To identify all P. tricornutum MYB (PtMYB) genes, the MYB gene family was analyzed a ...

5. Gene clusters for biosynthesis of mycosporine‐like amino acids in dinoflagellate nuclear genomes: Possible recent horizontal gene transfer between species of Symbiodiniaceae (Dinophyceae)

Author:

Journal of phycology 2022 v.58 no.1 pp. 1-11

Subject:
Symbiodinium; algology; amino acids; biosynthesis; corals; genomics; horizontal gene transfer; multigene family; photosynthesis; phylogeny; sexual reproduction; symbionts; temperature; ultraviolet radiation
Abstract:
... Global warming increases the temperature of the ocean surface, which can disrupt dinoflagellate‐coral symbioses and result in coral bleaching. Photosynthetic dinoflagellates of the family Symbiodiniaceae include bleaching‐tolerant and bleaching‐sensitive coral symbionts. Therefore, understanding the molecular mechanisms for changing symbiont diversity is potentially useful to assist recovery of co ...

Eucheuma; Kappaphycus alvarezii; algology; aquaculture; biofiltration; biomass; carbon dioxide; equations; fish; fish farms; nitrates; nutrient uptake; photosynthesis; solar radiation; thallus
Abstract:
... The declining production of commercially important eucheumatoids related to serious problems, like increasing susceptibility to ice–ice disease and epiphytism, may be ameliorated by nutrition. This ushered an increasing interest in incorporating seaweeds into an integrated multi‐trophic aquaculture (IMTA) setup to take up excess inorganic nutrients produced by fish farms for their nourishment. In ...

Abstract:
... In sessile organisms, phenotypic plasticity represents an important strategy for dealing with environmental variability. Here we test if phenotypic plasticity enables the common coral Stylophora pistillata to occupy a broad niche. We find clear differences in the photo‐physiology of four putative species of photosynthetic dinoflagellate symbionts associated with the coral S. pistillata, namely, Cl ...

Abstract:
... Marine heatwaves (MHWs), discrete periods of extreme warm water temperatures superimposed onto persistent ocean warming, have increased in frequency and significantly disrupted marine ecosystems. While field observations on the ecological consequences of MHWs are growing, a mechanistic understanding of their direct effects is rare. We conducted an outdoor tank experiment testing how different ther ...

Abstract:
... Diatom metacommunities are structured by environmental, historical, and spatial factors that are often attributed to organism dispersal. In the McMurdo Sound region (MSR) of Antarctica, wind connects aquatic habitats through delivery of inorganic and organic matter. We evaluated the dispersal of diatoms in aeolian material and its relation to the regional diatom metacommunity using light microscop ...
