phototropism

Some bacteria can alternate phototrophy and chemotrophy, depending on availability of light.

They are facultatively aerobic, but do not produce oxygen in the process of producing energy from light, or phototrophy.

They have already replaced phototrophy with heterotrophic absorption.

There are several nutritional strategies in dinoflagellates: phototrophy, mixotrophy and heterotrophy.

Additionally Chloroflexi have a different method of phototrophy (photoheterotrophy) than true photosynthetic bacteria.

There are two major types of phototrophy: chlorophyll-based chlorophototrophy and rhodopsin-based retinalophototrophy.

Chlorophototrophy can further be divided into oxygenic photosynthesis and anoxygenic phototrophy.

Thomas Demand: phototrophy.

Thus, it is likely that phototrophy independently evolved at least twice, once in bacteria and once in archaea.

Some prokaryotes express proton pumps called bacteriorhodopsins, proteorhodopsins, and xanthorhodopsins to carry out phototrophy.

Its best growth conditions are anaerobic phototrophy (photoheterotrophic and photoautotrophic) and aerobic chemoheterotrophy in the absence of light.

In both aerobic phototrophy and chemolithotrophy, oxygen is used as a terminal electron acceptor, while under anaerobic conditions inorganic compounds are used instead.

A.ferrooxidans is a chemolithoautotrophic bacteria, due to the oligotrophic nature (low dissolved organic carbon concentration) of acidic environments, and their lack of illumination for phototrophy.

While oxygenic phototrophs use water as an electron donor for phototrophy, Chloroflexus uses reduced sulfur compounds such as hydrogen sulfide, thiosulfate, or elemental sulfur.

When there is sufficient sunlight for it to feed by phototrophy, it uses chloroplasts containing the pigments Chlorophyll a and Chlorophyll b to produce sugars by photosynthesis.

Last, chlorophyll-based phototrophy is coupled to carbon fixation (the incorporation of carbon dioxide into larger organic molecules) and for that reason is photosynthesis, which is not true for bacteriorhodopsin-based system.

But the close derivation of the Metazoa from any alga requires, in addition to the origination of collagen, the loss of Iysine synthesis and the replacement of phototrophy by ingestion.

Energy metabolism of bacteria is either based on phototrophy, the use of light through photosynthesis, or based on chemotrophy, the use of chemical substances for energy, which are mostly oxidised at the expense of oxygen or alternative electron acceptors (aerobic/anaerobic respiration).

This phenomenon is called phototropism, which means bending toward the light.

The tendency to move or grow towards light is called phototropism.

Similar mechanisms are working in other tropic responses, such as phototropism.

The result was "Phototropism," 13 pieces written, choreographed and scored by the participants.

They are known for their strong phototropism response and helical growth of the sporangium.

His areas of expertise were photosynthesis, phototropism and algae.

He is mainly known for his work on plant hormones, specifically the role of auxin in phototropism.

He turned his chair to face straight into the sun; he has a phototropism that seems to amount to a form of homesickness.

There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism.

Light regulates three major plant processes: photosynthesis, phototropism, and photoperiodism.

A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.

Both root tips and most stem tips exhibit positive phototropism to red light.

Phototropin is the blue light photoreceptor that controls phototropism.

Among the common tropisms seen in plants is phototropism, the bending of the plant toward a source of light.

These responses are called phototropism and skototropism respectively.

Apart being itself the tropic factor (phototropism), light may also suppress the gravitropic reaction.

Where the specific stimulus is light, the phenomenon is phototropism ("light-turning" G).

Splice phototropism genes to growth ones, maybe?

In higher plants, chloroplast movement is run by phototropins, blue light photoreceptors also responsible for plant phototropism.

At least ten different genes (named madA through to madJ) are required for phototropism.

Auxin participates in phototropism, geotropism, hydrotropism and other developmental changes.

Experiments performed were used to explore the mechanisms of both blue-light- and red-light-induced phototropism in plants.

Phototropism in plants such as Arabidopsis thaliana is directed by blue light receptors called phototropins.

Dennstaedita punctilobula can exhibit varying degrees of phototropism.

These specialized hyphae usually show negative gravitropism and positive phototropism allowing good spore dispersal.
