For dynamic responses in plants, long-distance carbon (C) transport is required to support growth. Therefore, investigating C allocation in plants is crucial for developing a mechanistic understanding of plant functioning. However, little is known about short-term assimilate transport patterns and velocities, as literature values from singular and invasive measurements are hard to interpret for a highly susceptible system. To study the transport of photo assimilates within plants, we developed phenoPET, a plant dedicated positron emission tomography (PET) scanner. While PET scanners have been widely used in medical science since decades, their use in plant research is less common. For tracing the transport, carbon dioxide containing the short-lived positron-emitting isotope carbon-11 (<sup>11</sup>C) is applied as <sup>11</sup>CO<sub>2</sub> to a single leaf or the whole canopy of a living plant. The plant fixes CO<sub>2</sub> and the <sup>11</sup>C is subsequently transported in the form of photosynthates towards C sinks, e.g. through leaf and stem towards the root system. The decaying tracer can then be located inside the plant by detecting its radiation. To this end, the living plant is placed in the field-of-view of the scanner, which is a volume with a diameter of 18 cm and a height of 20 cm. A lifting table can move the scanner vertically and allows for repeated measurements of different regions of interest along the plant axis. The phenoPET system is located in a climate chamber equipped with LED panels in order to create defined environmental conditions. <br>In our presentation, we will highlight our workflow for gathering quantitative data on C tracer transport velocities between different plant types, single plants, for different plant parts, during a day, and over days. We believe that this will provide new insights into the functioning and dynamics of C transport processes in in the plant-soil system. 001043654 536__ $$0G:(DE-HGF)POF4-2171$$a2171 - Biological and environmental resources for sustainable use (POF4-217)$$cPOF4-217$$fPOF IV$$x0 001043654 588__ $$aDataset connected to CrossRef 001043654 65027 $$0V:(DE-MLZ)SciArea-160$$2V:(DE-HGF)$$aBiology$$x0 001043654 65017 $$0V:(DE-MLZ)GC-170-2016$$2V:(DE-HGF)$$aEarth, Environment and Cultural Heritage$$x0 001043654 7001_ $$0P:(DE-Juel1)173093$$aScherer, Benedikt$$b1 001043654 7001_ $$0P:(DE-Juel1)129360$$aMetzner, Ralf$$b2$$ufzj 001043654 7001_ $$0P:(DE-Juel1)129333$$aHuber, Gregor$$b3 001043654 7001_ $$0P:(DE-Juel1)131784$$aPflugfelder, Daniel$$b4$$ufzj 001043654 7001_ $$0P:(DE-Juel1)129303$$aChlubek, Antonia$$b5$$ufzj 001043654 7001_ $$0P:(DE-Juel1)165733$$aKoller, Robert$$b6 001043654 7001_ $$0P:(DE-HGF)0$$aKnief, Claudia$$b7 001043654 7001_ $$0P:(DE-Juel1)133959$$aWüstner, Peter$$b8 001043654 7001_ $$0P:(DE-Juel1)133962$$aZimmermann, Egon$$b9$$ufzj 001043654 7001_ $$0P:(DE-Juel1)142196$$aNatour, Ghaleb$$b10$$ufzj 001043654 773__ $$a10.5194/egusphere-egu25-4311 001043654 8564_ $$yRestricted 001043654 8564_ $$uhttps://juser.fz-juelich.de/record/1043654/files/EGU25-4311_Posrer_Streun.pdf$$yOpenAccess 001043654 909CO $$ooai:juser.fz-juelich.de:1043654$$pdriver$$pVDB$$popen_access$$popenaire 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)133944$$aForschungszentrum Jülich$$b0$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)173093$$aForschungszentrum Jülich$$b1$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129360$$aForschungszentrum Jülich$$b2$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129333$$aForschungszentrum Jülich$$b3$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131784$$aForschungszentrum Jülich$$b4$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129303$$aForschungszentrum Jülich$$b5$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)165733$$aForschungszentrum Jülich$$b6$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)133959$$aForschungszentrum Jülich$$b8$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)133962$$aForschungszentrum Jülich$$b9$$kFZJ 001043654 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)142196$$aForschungszentrum Jülich$$b10$$kFZJ 001043654 9131_ $$0G:(DE-HGF)POF4-217$$1G:(DE-HGF)POF4-210$$2G:(DE-HGF)POF4-200$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-2171$$aDE-HGF$$bForschungsbereich Erde und Umwelt$$lErde im Wandel – Unsere Zukunft nachhaltig gestalten$$vFür eine nachhaltige Bio-Ökonomie – von Ressourcen zu Produkten$$x0 001043654 9141_ $$y2025 001043654 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001043654 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001043654 920__ $$lyes 001043654 9201_ $$0I:(DE-Juel1)ITE-20250108$$kITE$$lInstitute of Technology and Engineering$$x0 001043654 9201_ $$0I:(DE-Juel1)IBG-2-20101118$$kIBG-2$$lPflanzenwissenschaften$$x1 001043654 980__ $$aposter 001043654 980__ $$aVDB 001043654 980__ $$aUNRESTRICTED 001043654 980__ $$aI:(DE-Juel1)ITE-20250108 001043654 980__ $$aI:(DE-Juel1)IBG-2-20101118 001043654 9801_ $$aFullTexts
