Strains are ordered according to the criteria for which they were selected for analysis. Selection criteria correspond to the topics important for evaluation of cellulase production in the respective mutant. The result of this evaluation was used to determine whether this gene may contribute to the efficiency of the cellulase mixture of Δwc-1, Δwc-2 or Δvvd. Mutants were checked for known growth defects http://www.broadinstitute.org/annotation/genome/neurospora/MultiHome.html webcite. Gene loci given in bold cause significantly altered specific cellulase activity or biomass accumulation on cellulose. Where available, data showed no indication of growth defects in the mutant strains used in this study
