Anthocyanins have many functions in plants. First they are brightly pigmented molecules, used in flowers to attract pollinators. They are also responsible for the color in leaves during autumn. Because they are pigmented, they can act as a plant's "sunscreen" protecting it from bleaching by the sun. Lastly, anthocyanins are powerfulantioxidants, which protect plants from the damage of oxygen radicals.
there is no phycoerythrin present in plants it is only found in red algae, cyanobacteria, cynelles, cryptomaonads and glaucophytes. so in higher plants must be anthocyanin.
Anthocyanin is a pigment in some plants (like blueberries) that absorbs all other colors of light in the light spectrum and reflects blue light.
my guess in that herbicides impacting the photosynthetic apparatus would be more likely to induce foliar anthocyanin accumulation compared with herbicides with modes of action unrelated to photosynthesis (like glyphosate). The anthocyanin accumulation is probably an attempt on the part of the plant to screen from excess radiation a damaged photosynthetic apparatus.
Red. Anthocyanin turns leaves red. Yes, it is spelled correctly!
It can be measured by UV- spectrophotometer. The pH differential method has been used to determine the anthocyanin content
