Molecular functional group images of the sorghum seed tissue from the pericarp (outside), seed coat, aleurone layer and endosperm [from left to right: visible image; chemical image, peak area of one peak; spectrum corresponding to the pixel at the cross hair in the visible image (spectrum pixel size: 10 µm × 10 µm)], using synchrotron-based infrared microspectroscopy at the NSLS. (a) Area under the 1725 cm⁻¹ peak (carbonyl C=O); (b) area under the 1655 cm⁻¹ peak (amide I); (c) area under the 1650 cm⁻¹ peak (amide II); (d) area under the 1515 cm⁻¹ peak (aromatic compound); (e) height under the 1428 cm⁻¹ peak (cellulosic compound); (f) height under the 1371 cm⁻¹ peak (cellulosic compound); (g) area under the 1245 cm⁻¹ peak (cellulosic materials); (h) area under the 1185–950 cm⁻¹ peak (total CHO); (i) area under the 1160 cm⁻¹ peak (CHO); (j) area under the 1150 cm⁻¹ peak (CHO); (k) area under the 1080 cm⁻¹ peak (CHO); (l) area under the 1025 cm⁻¹ peak (starch); (m) area under the 930 cm⁻¹ peak (CHO); (n) area under the 860 cm⁻¹ peak (CHO); (o) area under the 3350 cm⁻¹ peak (OH and NH: protein and CHO).
