PAEXG1 and PAEXG2 are separately and sequentially disrupted. The resulting mutant strains show a significantly reduced efficiency of biocontrol of Botrytis cinerea. When applied to wounded apple fruit, the calculated protection level dropping from 71% (parental strain) to 8% (mutated strain). Exo-beta-1,3-glucanases play a role in the biological control of Botrytis cinerea on apple
