Fig. 7From: A label-free, fast and high-specificity technique for plant cell wall imaging and composition analysisExample of quantification of lignin in stems using SRS images. SRS images of wild-type (WT) and 35S:MIR408-overexpressing poplar plants acquired at 1600 cm−1, showing the lignin distribution. Color code indicates an increase of the signal intensity from blue to red. Scale bars = 50 µmBack to article page
