Expression of orthologous genes encoding enzymes involved in the Leloir (a) and the D-galactose oxido-reductive pathway (b) in A. niger.

The expression was measured in the reference and regulatory mutant strains of A. nidulans after 2h of growth on D-fructose (black bars) and D-galactose (checkered bars). The columns represent the mean and error bars represent standard deviation between biological replicates. Significant change in expression between the reference strain and the mutant was marked by the asterisk. Significant changes in expression between single and double mutants were marked by Greek symbols and braces: an alpha (α) represents a significant change between ΔA and ΔAΔG, a beta (β) represents a significant change between ΔG and ΔXΔG/ΔAΔG, a gamma (γ) represents a significant change between ΔX and ΔXΔG.
