title: Transformation with green fluorescent protein of Trichoderma harzianum 1051, a strain with biocontrol activity against Crinipellis perniciosa, the agent of witches'-broom disease of cocoa.
abstract: A plasmid vector for fungal expression of an enhanced, red-shifted variant of the Aequoria victoriae green fluorescent protein was constructed by fusion of the EGFP gene to the highly expressed Aspergillus nidulans gpd promoter and the A. nidulans trpC terminator. This construction was introduced by cotransformation, using benomyl selection, into Trichoderma harzianum strain 1051, a strain being evaluated for the biological control of witches'-broom disease of cocoa caused by Crinipellis perniciosa. Epifluorescence microscopy was used to monitor germination and attachment of stable transformant conidia on the surface of C. perniciosa hyphae.
