Figure 7. Expression levels of GH 18 chitinases and GH 20 hexosamidases in the midgut.

Genes encoding enzymes with putative roles in the breakdown of the N-acetylglucosamine polymer, chitin, were impacted by the feeding substrate. RPKM values were computed using the ‘rpkm’ function in edgeR. *p < 0.05; **p < 0.01, **p < 0.001.
