Figure 2From: A novel platform for heterologous gene expression in Trichoderma reesei (Teleomorph Hypocrea jecorina) Use of pyr2 for genetic deletion and direct repeat recombination. A: Genetic deletion using pyr2 as selectable marker. B: Elimination of pyr2 by direct repeat recombination, selected for by subjection to 5-FOA. GOI: Gene of interest, FL1: Upstream flank, FL2: Downstream flank, R: Direct repeats.Back to article page
