Table 2 Frequencies of intramolecular homologous recombination between direct repeats (DRs) of different lengths

From: Reversible impairment of the ku80 gene by a recyclable marker in Aspergillus aculeatus

Strain mrTA20 mrTA98 mrTA495
Length of DR (bp) 20 98 495
No. of 5-FOA-resistant strains 6 14 120
No. of resistant strains analyzed 6 6 10
No. of uridine auxotrophs 6 4 9
No. of homologous recombination events between DRs 3 3 9
  1. The 5-fluoroorotic acid (5-FOA) resistant strains were isolated from 1.0 × 106 conidia.
