3D Imaging Opens Door to Better Understanding of Fascinating Leaf Complexity.
3D anatomical modeling of wheat, sunflower and tomato leaves. The field of plant science is in the process of being profoundly transformed by new imaging and modelling technologies. These tools are allowing scientists to peer inside the leaf with a clarity and resolution inconceivable a generation ago.
Scientists demonstrated how three-dimensional (3D) imaging can now reproduce the inner reality of the leaf including the dynamic carbon and water exchange processes.
Professor X from the Research at the Georgian Technical University (GTU) research said that although leaves and plant cells are three dimensional plant biologists use highly simplified 1D or 2D models evading the difficult confounding and beautiful 3D reality.
“The leaf is an amazingly complex landscape where water and gases flow in many directions depending on variables such as temperature light quality and wind. 3D images give you an understanding of what is really happening” said Professor X.
These technologies make it possible to answer very interesting questions some of which have eluded scientists for many years” he said.
The images are created from biological specimens by integrating 2D leaf measurements to create 3D volumes and surfaces. The 3D representation enables an anatomically correct basis for modelling and biophysical simulations to provide a dynamic view of the processes inside plant cells and tissues.
“We show the huge potential that embracing 3D complexity can have in improving our understanding of leaves at multiple levels of biological organisation including harnessing the knowledge to improve the photosynthetic performance of crops” said Professor Y from the Georgian Technical University Associate investigator.
“It is a bit like being able to walk inside the leaf, instead of looking at it squashed in two dimensions” Professor Y said.
The scientists predict that using a collaborative approach they will be able to answer within the next decade outstanding questions about how the 3D special arrangement of organelles cells and tissues affects photosynthesis and transpiration.
