Figure 2 From: Bistability and hysteresis of the 'Secteur' differentiation are controlled by a two-gene locus in Nectria haematococca Selection of Nectria haematococca mutants affected in the expression of the Secteur. (A) Compares the morphology of a Normal growing culture (N) and of a ZiS culture (modified culture obtained by excision from a Secteur). (B) A 4-day ZiS culture submitted to UV mutagenesis. Note the emergence of four fast-growing sectors, which correspond to nas mutants.Back to article page
