T. hamatum biocontrol and plant disease suppression. (A) Leaf segments of rice (cultivar CO-39) showing rice blast symptoms. (B) Suppression of rice blast disease by T. hamatum. Growth of rice cultivar CO-39 in soil amended with T. hamatum GD12 (white bars) and the N-acetyl-β-D-glucosaminidase deficient mutant ΔThnag1::hph (gray bars) reduced the size of the lesions caused by the rice blast Magnaporthe oryzae. Lesions were scored as previously documented (Valent et al., 1991) according to the following range. Type 1 (lesion 0.5 mm in length); type 2 (lesion ~1 mm in length); type 3 (lesions ~2 mm in length) and type 4 (lesions ~3–4 mm in length) lesions. Each bar represents the mean of 8 samples, each with 5 experimental replicates ± SE.
