New CO2 microsensor reveals old secrets of plants

2018-10-16· We fixed the tiny CO 2 and O 2 microsensors on a micromanipulator in order to position both sensors in the same leaf on either the CAM or the C 3 plant. In this way, we were able to assess the diel oscillations of both gases simultaneously. In C 3 plants, CO 2 inside the leaves increased to ~ kPa (75-fold CO 2 in air) during darkness. For the CAM plant, CO 2 was mostly below kPa due to ...
