Plant structure visualization by high-resolution X-ray computed tomography

New developments in high-resolution X-ray computed tomography (HRXCT) are promising for the broader application of this non-destructive imaging method in plant sciences. Here, we demonstrate how detailed three-dimensional morphological traits can be extracted rapidly from in vivo Arabidopsis thaliana seedlings without sample manipulation. Furthermore, ex vivo scanning at sub-micron resolution allows the quantification and visualization of the cellular organization of plant tissue samples, making HRXCT a desired tool in developmental plant biology.
