Identification of hac1- and bip1- overexpression in isolated transformants with improved cellulase-producing ability. a, b Copy numbers of hac1 (a) and bip1 (b) in the transformants as determined by quantitative PCR. The expressing cassettes for only hac1 or bip1, but not the other four genes, were found in the seven strains with improved cellulase-producing ability. c, d The relative transcript levels of hac1 (c) and bip1 (d) in these transformants as analyzed by RT-qPCR
