Abstract

Plant cell walls are highly complex structures, which are adaptable to various environmental stresses. While many biochemical pathways have been discovered, cellular stress indicators are widely unknown. Here we demonstrate a label-free optical setup, that can map both mechanical properties and chemical composition in biological samples. We measured changes in mechanical stiffness and chemical response of rose leaf cells due to inoculation of the fungal disease Diplocarpon rosae. With this we are able to image fungal growth in a dynamical and high-resolution manner.
