Abstract Background Polyphenol oxidase PPO activity in plants is a trait with potential economic agricultural and environmental impact. In relation to the food industry PPO-induced browning causes unacceptable discolouration in fruit and vegetables from an agriculture perspective PPO can protect plants against pathogens and environmental stress improve ruminant growth by increasing nitrogen absorption and decreasing nitrogen loss to the environment through the animal s urine. The high PPO legume red clover has a significant economic and environmental role in sustaining low-input organic and conventional farms. Molecular markers for a range of important agricultural traits are being developed for red .
