1. Antagonistic potentials of QM 6a and the pks4-1 deletion mutant.
Antagonistic potentials of QM 6a and the pks4-1 deletion mutant. Confrontations panels are shown only for Δpks4-1, but both mutants revealed identical mycoparasitic patterns. (a) Front sides of confrontation plates, with plant-pathogenic fungi always on the left side and Trichoderma QM 6a or the mutant always on the right. (b) Back sides of confrontation plates, with plant-pathogenic fungi always on the left side and T. reesei QM 6a or the mutant strain always on the right. Antibiosis zones for Δpks4 strains are indicated by the arrows. Aa, Ss, Bs, and Rs mark Alternaria alternata, Sclerotinia sclerotiorum, Botrytis cinerea, and Rhizoctonia solani, respectively.
