Natural populations of Hypsizygus marmoreus in Japan exhibit diverse incompatibility factors with significant regional differences, especially for B loci.
- Why it matters: Understanding the distribution of incompatibility factors is crucial for improving breeding efficiency in this major cultivated mushroom species.
- What they did: Researchers analyzed 71 wild isolates from different Japanese regions, identifying 82 monokaryons with different alleles at both A and B loci and 60 shared factors, using mating tests with tester strains.
- The result: Findings suggest incompatibility factors are randomly distributed within regions but vary significantly among regions, indicating ecological and evolutionary influences like dispersal and balancing selection shape their geographical distribution.
