Fig. 3

Averaged Raman spectra (a, b) acquired from LMS−1 lunar regolith-grown A. thaliana, and regolith washed with proline, ascorbic acid, glutathione, and antioxidants. Changes in the intensities of vibrational bands that can be assigned to carotenoids, (1525 cm−1) and cellulose (1048 cm−1) are reported by ANOVA graphs (c). Means of the intensities of vibrational bands are shown by dots; standard deviations by horizontal lines.
