These are also known as limiting factors. They can limit the rate of photosynthesis if it is in short supply. OK, well I guess farmers can't control these limiting factors outside, can they?

Photosynthesis is one of nature’s most efficient ... and enables the formation of long-lived excitons, a crucial factor for harvesting solar energy. In polar solvents, the system demonstrated ...

and transcription factors in regulating light-responsive genes in plants. Their findings are published in PNAS. Light is not only the primary energy source for photosynthesis but also a crucial ...

A group of diatom species belonging to the Nitzschia genus gave up on photosynthesis and now get their carbon straight from their environment, thanks to a bacterial gene picked up by an ancestor.

With artificial photosynthesis, humankind could utilize solar energy to bind carbon dioxide and produce hydrogen. Chemists have taken this one step further: They have synthesized a stack of dyes ...
