Lead author Nigel D'Souza, then a postdoctoral researcher at Lamont, discovered the phytoplankton response to oil seeps while on a ship in the Gulf of Mexico monitoring chlorophyll fluorescence — energy that is emitted as light by compounds inside phytoplankton cells used for photosynthesis.

As the LRAUVs move through the ocean, they collect information about water temperature, chemistry, and chlorophyll (an indicator of microscopic algae) and send this data to scientists on shore or on a nearby ship.

Their pigments (possibly bacteriochlorophylls) were predecessors to chlorophyll.

The researchers showed that the conversion of chlorophyll a to chlorophyll f requires only this one enzyme in a simple system that could represent an early intermediate stage in the evolution of photosynthesis.

TerraLeaf is working on using chlorophyllin — the chlorophyll from a plant turned into a salt by adding sodium ions and copper — paired with an electrically conducting polymer to form a membrane that can pull CO2 (or other greenhouse gases) from air and form carbon - based chemicals, and potentially even fuels.

Different pigments serve different functions: Green chlorophyll, which dominates during the growing season, absorbs light energy for photosynthesis, the conversion of carbon and water to sugar.

Just like their red algal ancestors, cryptophytes utilise not only the green pigment chlorophyll for harvesting light, but have also the capability to use green light being missed by chlorophyll.

The experiment showed that, without this enzyme, these cyanobacteria could no longer synthesize chlorophyll f. By artificially adding the gene that encodes the enzyme, the researchers also showed that this one enzyme is all that is necessary to convert cyanobacteria that normally do not produce chlorophyll f into ones that can produce it.

Silk continued to adapt the microscope so that it could, like high - end fluorescent microscopes, detect materials such as chlorophyll or fluorescent dyes, which emit light when irradiated with specific light wavelengths.

If the enzyme is an evolutionary predecessor of Photosystem II, then evolution borrowed an enzyme that was originally used for chlorophyll synthesis and used it to evolve an enzyme that could produce oxygen, which ultimately led to changes in Earth's atmosphere,» said Bryant.

Her efforts allowed her to discover that single - cell plants that were exposed to aldehydes did end up with less chlorophyll — the green pigment in plants that absorbs light and plays a key role in photosynthesis.
