Generally, the expression of Sl1-MMP, Sl3-MMP, Sl4-MMP and Sl5-MMP was significantly induced with peaks at 48 h whereas the expression of Sl2-MMP was induced significantly with peaks at 24 h after infection with B. cinerea, as compared with those in the mock-inoculated plants (Fig. 2a). The gene discussed is MMP10; the disease is infection.
