The Photoprotective Role of Anthocyanin Pigments in Leaf Tissues
Anthocyanins are vacuolar pigments most commonly responsible for red to purple coloration in plant tissues. Because they absorb strongly in the blue-green waveband, anthocyanins effectively reduce internal light within the leaf, which may be beneficial under high-light stress conditions. However, …
