After infection with B. bassiana, the relative expression pattern of Sfructl4 was synchronized with that of Sfrustat5B, indicating that in S. frugiperda, the JAK/STAT signaling pathway was activated after infection with B. bassiana, and Sfructl4 and Sfrustat5B might play an important role in antifungal immune response (Liu et al., 2015). This evidence concerns the gene SOAT1 and infection.
