520 |a Bacillus tequilensis DZY 6715 was isolated from healthy leaves in Camellia oleifera, and the strain DZY 6715 significantly inhibited anthracnose disease resulting from Colletotrichum fructicola in C. oleifera, besides, its associated mechanism of disease resistance was explored. B. tequilensis DZY 6715 treatment controlled mycelial growth of C. fructicola in C. oleifera, and significantly decreased C. oleifera anthracnose incidence and disease index compared with the control group. B. tequilensis DZY 6715 has strong biofilm forming ability, and also secretes extracellular β-1, 3-glucanase and chitinase, which could cause cell membranes damage and increased cellular compound leakage. C.oleifera treated with DZY 6715 also effectively enhanced enzyme activities and stimulated the synthesis the substances related to phenylpropane metabolism and reactive oxygen metabolism. Moreover, transcript profiling analysis revealed more differentially expressed genes related to phenylpropanoid pathway metabolism and antioxidant system inducing by DZY 6715 compared with the control in C. oleifera. Thus, it can be concluded that B. tequilensis DZY 6715 is a suitable bio-control agent to control anthracnose disease in C. oleifera
