Erratum to: Genome sequencing of the Trichoderma reesei QM9136 mutant identifies a truncation of the transcriptional regulator XYR1 as the cause for its cellulase-negative phenotype.

Following the publication of our recent article in BMC Genomics [1] we wish to bring the following corrigendum to your attention. In the above paper, we wrote in the discussion on page 13: “These are V756F in XlnR (corresponding to V801 in XYR1) and A804V (based on our analysis; not A824V as stated by the authors) in XYR1”. Our analysis of the XYR1 sequence was based on the available Trichoderma reesei QM6a XYR1 sequences deposited in the NCBI database [Protein Accession Number XP_006966092.1 and EGR48040.1]. Recently, Derntl et al. [2] identified that the second intron in xyr1 is in fact not spliced thus giving rise to a protein that, while maintaining the reading frame, is 20 amino acids longer. Consequently, the position A824V given by Derntl et al. [2] is correct, and the numbering of amino acids in our paper after G319 has to be increased by 20.

A corrected version of our statement would read: "These are V756F in XlnR of A. niger which corresponds to V821 in T. reesei XYR1, as well as A824V in XYR1 of T. reesei [35, 42]".

We apologize for this mistake, but would like to stress that none of the results or conclusions in our paper are affected by this change.
