Heterokaryon-Incompatibility Factor Interaction in Tests between Neurospora Mutants.
Studies on presumably isogenic ad-3A and ad-3B mutants of the ascomycete Neurospora crassa derived from the same wild-type strain have revealed that the negative heterokaryon tests shown by certain pairwise combinations can be attributed to interaction of incompatibility factor mutations.
