Physiologic processes affecting the content and distribution of phytonutrients in plants

Plant physiologists and biochemists are unraveling the transport mechanisms and biosynthetic pathways that determine each plant’s unique phytonutrient composition so that crop plants can be modified to improve their nutrition quality. However, before this goal can be achieved, more information is needed on various plant and human phytonutrient-related processes, and some new technical capabilities are required. The current status of our knowledge base and recommendations for technical improvements and research priorities will be discussed.
