Determination of Root Exudate Concentration in the Rhizosphere Using 13C Labeling
Authors:  Laurent Simon and Feth el Zahar Haichar, date: 05/05/2019, view: 244, Q&A: 0
One of the most remarkable metabolic features of plant roots is their ability to secrete a wide range of compounds into the rhizosphere, defined as the volume of soil around living roots. Around 5%-21% of total photosynthetically fixed carbon is ...
