SACM1L and infection: Several genes have been reported in regulating infection cushion development, such as Sac1, Ss-caf1, Ss-oah1, Ss-odc2, and Smk3 (Jurick and Rollins, 2007; Li et al., 2012; Xiao et al., 2014; Liang et al., 2015a; Liang et al., 2015b; Bashi et al., 2016), meanwhile Ggt1, Sac1, and Smk3 are downregulated in SsNR-silenced mutants, indicating that SsNR is involved in the expression of infection cushion development-related genes in fine-tuning the infection cushion formation process during penetration of S. sclerotiorum.
