Carnivorous sundews actively capture their prey. But in contrast to the related Venus flytraps, sundews are not responding to touch or other mechanical stimulants. Now Chinese researchers show that a small peptide, glutathione, likely released by the captured fly, signals for the trap to close.

How plants photosynthesize
Sometimes it seems that plants grow spontaneously. This all is due to maybe one of the coolest tricks of plants in that they produce their own food. Photosynthesis plays a major role in this process.
Where almond trees store energy can affect yield
Perennial plants store carbohydrates to bridge carbon shortages. Like those in the winter for example. Now American researchers show that it matters where a plant creates those carbohydrate stores.
CO2 regulates stomata opening
Stomata, the pores on the underside of the leaf, let CO2 in for photosynthesis and water vapour out. Now researchers show that by an increasing of CO2 in the atmosphere plants are not using this to fix more energy but for saving water.
