Dr. Universe: How do cacti survive in hot, dry environments?

Dr. Universe. A cartoon cat in a lab coatAll plants need water to survive. Those that live in places where water is scarce use some interesting strategies to stay alive.

That’s what I found out from my friend Charles Cody, who manages one of the greenhouses at Washington State University. When I went to visit the greenhouse, he pointed out a few different cacti. One was tall and cylindrical with big spines. Another was » More …

Plant inner workings point way to more nutritious crops

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 …
