Table 3 Phenotypes of heterokaryotic mycelia from various pairings

From: Bistability and hysteresis of the 'Secteur' differentiation are controlled by a two-gene locus in Nectria haematococca

  1. aAS differentiates both Anneaux and Secteurs and synthesize α and σ only in the respective modified areas. As* differentiates Anneaux but not Secteurs, though they have the σ determinant throughout the mycelium; As differentiates Anneaux but not Secteurs and never contain the σ determinant.
