Plant inner workings point way to more nutritious crops

plant interior animation still imageAlmost every calorie that we eat at one time went through the veins of a plant. If a plant’s circulatory system could be rejiggered to make more nutrients available – through bigger seeds or sweeter tomatoes – the world’s farmers could feed more people.

Washington State University researchers have taken a major step in that direction by unveiling the way a plant’s nutrients get from the leaves, where they are produced through photosynthesis, to “sinks” that can include the fruits and seeds we eat and the branches we process for biofuels. The researchers found a unique and critical structure where the nutrients are offloaded, giving science a new focal point in efforts to improve plant efficiency and productivity. » More …
