Agrobacterium-mediated transformation of Aspergillus awamori in the absence of full-length VirD2, VirC2, or VirE2 leads to insertion of aberrant T-DNA structures.

Abstract excerpt

Reductions to 2, 5, and 42% of the wild-type transformation efficiency were found when Agrobacterium mutants carrying transposon insertions in virD2, virC2, and virE2, respectively, were used to transform Aspergillus awamori. The structures of the T-DNAs integrated into the host genome by these mutants were analyzed by Southern and sequence analyses. The T-DNAs of transformants obtained with the virE2 mutant had...
