Maps of pBT, pBT-BbJEN1P-egfp, pBT-BbJEN1P-gus, pBFT, the overexpression vector for BbJEN1 (pBFT-BbJEN1), and the disruption vector for BbJEN1 (pBFT-BbJEN1L/R). PgpdA is the promoter of gpd from Aspergillus nidulans, bar is the herbicide resistance gene, egfp is the enhanced green fluorescent protein gene, gus is the β-glucuronidase gene, TtrpC is the terminator of trpC from A. nidulans, BbJEN1 is the carboxylate transport protein gene, and BbJEN1p is the promoter of BbJEN1 gene in B. bassiana.
