| Research Abstract |
We report the successful Agrobacterium tumefaciens-mediated transformation (AMT) of Aspergillus aculeatus for functional genomics. We isolated 40 transformants expected to be disruptants of the regulator(s) controlling cellulase gene expressions in A. aculeatus from 15,000 transformants obtained by AMT. Mutation of the geneA resulted in 5-fold reduction on cellobiohydrolase gene expression in transformant by comparing with that in host strain. Now, we are further analyzing the function of putative transcription factor identified in this study and seeking the other regulators.
