In order to identify the bio-control related genes from Trichoderma harzianum,Chaetomium cuperium and C. globosum, the expressed sequence tags (ESTs) of these plant disease bio-control fungi were determined. The cDNA libraries of those fungi were constructed from their mycelia and induced cultures. ESTs of the fungi were sequenced. Analysis of those sequences showed that more than 100 genes from the fungi are plant disease bio-control related genes although more possible bio-control related genes are still to be investigated. The biocontrol related genes are very important for new bio-fungicide development in the future.
