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 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

Endosymbiotic Evolution of Algae, Secondary Heterotrophy and Parasitism [PDF]

open access: yesBiomolecules, 2019
Photosynthesis is a biochemical process essential for life, serving as the ultimate source of chemical energy for phototrophic and heterotrophic life forms. Since the machinery of the photosynthetic electron transport chain is quite complex and is unlikely to have evolved multiple independent times, it is believed that this machinery has been ...

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 ...

Towards universal synthetic heterotrophy using a metabolic coordinator

Metabolic Engineering, 2022
ABSTRACT Engineering the utilization of non-native substrates, or synthetic heterotrophy, in proven industrial microbes such as Saccharomyces cerevisiae represents an opportunity to valorize plentiful and renewable sources of carbon and energy as potential inputs to biotechnological

Heterotrophy in the Lemnaceae

Journal of Plant Physiology, 1994
Summary Lemna minor L. and Wolffia brasiliensis Weddell can use sucrose to support heterotrophic growth in darkness and photomixotrophic growth in the light, but each is killed by galactose in the medium. Spirodela punctata (G. F. W. Meyer) Thompson growth on sucrose and galactose was indistinguishable. L.

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.
