Heterotrophy in Tropical Scleractinian Corals

Biological Reviews, 2009
AbstractThe dual character of corals, that they are both auto‐ and heterotrophs, was recognized early in the twentieth Century. It is generally accepted that the symbiotic association between corals and their endosymbiotic algae (called zooxanthellae) is fundamental to the development of coral reefs in oligotrophic tropical oceans because zooxanthellae

On the Origin of Heterotrophy

Trends in Microbiology, 2016
The theory of autotrophic origins of life posits that the first cells on Earth satisfied their carbon needs from CO2. At hydrothermal vents, spontaneous synthesis of methane via serpentinization links an energy metabolic reaction with a geochemical homologue.

Heterotrophy of particulate organic matter subsidies contributes to divergent bleaching responses in tropical Scleractinian corals

Limnology and Oceanography
Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching.

AUXOTROPHY AND HETEROTROPHY IN MARINE LITTORAL DIATOMS

Canadian Journal of Microbiology, 1960
Forty-four pure cultures of marine littoral diatoms (43 pennate and 1 centric) have been studied to determine (a) whether any accessory organic factors (vitamins) are essential for growth in light, and (b) whether the cells can grow in darkness using glucose, acetate, or lactate as substrates.Six isolates were shown to require thiamine as sole growth ...

Facultative Heterotrophy in Some Chlorococcacean Algae

Science, 1961
All known species of the genera Bracteacoccus , Spongiochloris , and Dictyochloris , and some of the species of Neochloris and Spongiococcum are capable of growing heterotrophically in darkness in a glucose-salts medium ...

Screening Arthrospira (Spirulina) strains for heterotrophy

Journal of Applied Phycology, 2005
Thirty-five clonal, axenic Arthrospira strains were screened for their ability to grow heterotrophically on six carbon sources (20 mM). Glucose (34 strains) and fructose (24 strains) were the only substrates permitting growth in the dark. In some assays, however, not every replicate grew and, in at least one strain (D867), repeat assays over 2 years on

Molecular analysis of sugar transporters and glycolysis pathways in Ettlia sp. under heterotrophy using fructose and glucose

Biotechnology Journal, 2021
Fructophilic behavior in microalgae is a rare trait that could benefit biorefineries by enabling substitution of carbon source with fructose, and our previous study identified that Ettlia sp. prefers fructose relative to glucose.

Leaf Transition from Heterotrophy to Autotrophy is Recorded in the Intraleaf C, H and O Isotope Patterns of Leaf Organic Matter.

Rapid Communications in Mass Spectrometry, 2020
RATIONALE Quantitatively relating 13 C/12 C, 2 H/1 H and 18 O/16 O ratios of plant α-cellulose and 2 H/1 H of n-alkanes to environmental conditions and metabolic status should ideally be based on the leaf, the plant organ most sensitive to environmental ...

The evolutionary ecology of myco‐heterotrophy

New Phytologist, 2005
SummaryNonphotosynthetic mycorrhizal plants have long attracted the curiosity of botanists and mycologists, and they have been a target for unabated controversy and speculation. In fact, these puzzling plants dominated the very beginnings of the field of mycorrhizal biology.

Autotrophy and heterotrophy in root herniparasites

Trends in Ecology & Evolution, 1989
More than 3000 species of flowering plants are at least partially parasitic, acquiring water and solutes from the host via haustoria. More than one third of all parasitic angiosperms - the root hemiparasites - possess green leaves and root systems.
