    摘要: The invention relates to a process for identifying gene(s)/genetic element(s) associated with mating impairment in strains of Trichoderma reesei QM6a or strains derived thereof comprising the steps of a) providing a first strain being a Trichoderma reesei QM6a strain having a MAT1-2 locus or a strain derived thereof, b) sexually crossing said strain with a second strain being a mating competent strain of a Trichoderma reesei (Hypocrea jecorina) strain having a complementary locus, i.e. the MAT1-1 locus, c) repeatedly back-crossing the MAT1-1 progenies from the crossing of b) or the back-crossing thereof with the first strain of a), until a strain is obtained that is substantially identical to the first Trichoderma reesei QM6a strain or a strain derived thereof, but carries the MAT1-1 locus and is mating competent for crossing with Trichoderma reesei QM6a or any of its MAT1-2 progeny, d) selecting the progeny from step c) that is mating competent for crossing with a Trichoderma reesei (Hypocrea jecorina) having a MAT1-2 locus, and e) identifying the gene(s)/genetic element(s) associated with mating impairment by comparing the genome of the progenies selected in step d) with the genome sequences of the first strain of a) whereby said gene(s)/genetic element(s) may be fully or partially missing or existing in a mutated form or in a form having deletions or insertions in the first strain thus being a gene or a genetic element directly or indirectly associated with mating impairment in strains of Trichoderma reesei QM6a or a strain derived thereof as well as to a process for correcting the mating impairment of a Trichoderma reesei QM6a strain or a strain derived thereof having a MAT1-1 locus and that is not competent to mate with a Trichoderma reesei QM6a strain having a MAT1-2 locus or a strain derived thereof, wherein one or more mutated or fully or partially missing gene(s) and/or genetic element(s) identified as above is/are replaced by or complemented with the corresponding functional gene(s) and/or genetic element(s). Moreover, the invention relates to the use of a thus obtained fungal strain of the genus Trichoderma in industrial breeding and production of a product of interest. Moreover, the invention relates to the genes associated with mating impairment of Trichoderma reesei QM6a and strains derived therefrom and to genes essential for mating of Trichoderma reesei QM6a and strains derived therefrom.

    摘要: The invention relates to a recombinant DNA molecule encoding a polypeptide having phytase activity and increased temperature stability and increased proteolytic stability of the enzyme activity. The DNA sequence has been obtained by variation of the mature wild-type E. coli phytase sequence with defined amino acid positions being modified in comparison to the wild-type sequence or with the sequences having N- and/or C-terminal extensions, respectively. The invention further relates to a method for expressing the recombinant phytase as well as its use in the food and animal feed technologies.
