Maeda Lab Outreach In plants, aromatic amino acids are used to make colorful pigments, such as anthocyanins and betalains. These pigments also have important nutritional and pharmacological value to humans. To help disseminate the broader impact of our plant metabolism research in general public, we are currently developing an outreach event called “Pigment-Art”. What is “Pigment-Art”?
When and where?
Who are involved?
