The complex Arom locus of Aspergillus nidulans. Evidence for multiple gene fusions and convergent evolution.

abstract：:Cells of all living organisms contain complex signal transduction networks to ensure that a wide range of physiological properties are properly adapted to the environmental conditions. The fundamental concepts and individual building blocks of these signalling networks are generally well-conserved from yeast to man; y...
