From Molecule to Meaning: Click and Bioorthogonal Chemical Reporters for Plant Systems, Biological Imaging, and Artistic Expression.

Chemical biology has reshaped the ability to investigate complex biological systems at the molecular level. In this context, chemical reporters have become important tools for labeling and tracking biomolecules in living systems with spatial and temporal precision. In plant biology, they provide an alternative to genetic approaches and allow the study of dynamic processes in species or organs that are not easily accessible. Through the use of click and bioorthogonal chemistry, small-molecule probes can be metabolically incorporated into specific molecular scaffolds such as sugars, monolignols, amino acids, and lipids. These probes make it possible to follow events like glycosylation, lignification, lipid turnover, or protein synthesis in living plant tissues. This review presents an overview of current chemical reporter strategies, from molecular design and synthetic considerations to their application in plant imaging. Herein, how these tools have contributed to the development of plant chemical biology by enabling precise and modular investigations of plant structure and metabolism is described. Herein, it is also examined how chemical reporters have entered interdisciplinary contexts, including collaborations between science and the arts. By converting molecular-level information into visual and sensory formats, these approaches open new perspectives for research, education, and communication across scientific and creative disciplines.
