Figure 6From: Comparative genomics of parasitic silkworm microsporidia reveal an association between genome expansion and host adaptationA hypothetical model showing how the SPN protein of N. bombycis suppresses the serine protease cascade of the melanization pathway of the host B. mori . After the suppression of the serine protease cascade, the defensive response, the subsequent formation of melanization will be inhibited in the hosts. Abbreviation: PPO, prophenoloxidase; β-GRP, β-glucan recognition protein.Back to article page
