Given the task definition and input, reply with output. Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Context: To investigate the efficiency of Agrobacterium tumefaciens mediated transformation of Aspergillus fumigatus by using pyrG as a recessive selectable marker.', 'FAP1 and SHO1 genes target sequences, composed of a selectable marker pyrG and the flanking sequences of the FAP1 and the SHO1 genes, were cloned into a binary plasmid pDHt/sk, respectively. The produced plasmids were transformed into A. tumefaciens. The A. tumefaciens and uracil auxotroph A. fumigatus were cocultured in induction medium without uricil and uridine at 24 degrees C for 48 h. To inhibit growth of A. tumefaciens and to select transformants, the cultures were transferred to 37 degrees C and incubated for another 48 h.', 'In this study, A. tumefaciens-mediated transformation of A. fumigatus produced high homologous recombination rates, which was 44% (7 of 16) for FAP1 and 35% (7 of 20) for SHO1.
Answer: Our study showed that A. tumefaciens-medidated transformation by using pyrG as a recessive selectable marker is an efficient tool for target gene deletion of A. fumigatus.
Is [ Agrobacterium tumefaciens-mediated transformation of uracil auxotroph Aspergillus fumigatus an efficient method for target gene knockout ]?
