Fig. 5From: In vivo quantitative imaging of photoassimilate transport dynamics and allocation in large plants using a commercial positron emission tomography (PET) scanner 11C allocation at different times after 11CO2 administration. Quantification of 11C-allocation from three emission scans performed 2Â h, 3Â h, and 4Â h after 11CO2 administration to the leaf of a 70 DAP sorghum plant. Each data point represents decay-corrected 11C-radioactivity (MBq) measured in that ROI, except for total export which represents total radioactivity exported from the leaf for each scanBack to article page
