Nuclear physics detector technology applied to plant biology research

Journal Article

The ability to detect the emissions of radioactive isotopes through radioactive decay (e.g. beta particles, x-rays and gamma-rays) has been used for over 80 years as a tracer method for studying natural phenomena. More recently a positron emitting radioisotope of carbon: 11 C has been utilized as a 11 CO 2 tracer for plant ecophysiology research. Because of its ease of incorporation into the plant via photosynthesis, the 11 CO 2 radiotracer is a powerful tool for use in plant biology research. Positron emission tomography (PET) imaging has been used to study carbon transport in live plants using 11 CO 2 . Presently there are several groups developing and using new PET instrumentation for plant based studies. Thomas Jefferson National Accelerator Facility (Jefferson Lab) in collaboration with the Duke University Phytotron and the Triangle Universities Nuclear Laboratory (TUNL) is involved in PET detector development for plant imaging utilizing technologies developed for nuclear physics research. The latest developments of the use of a LYSO scintillator based PET detector system for 11 CO 2 tracer studies in plants will be briefly outlined. © 2012 Elsevier B.V. All rights reserved.
