Influence of Cytoplasm Factor on Asymmetric Recovery of Nuclear Types from Dikaryons in Lentinula edodes

This study has determined the genetic relations between the phenomenon of significant asymmetric ratio of the two component nuclear types from dikaryons and cytoplasm factors in Lentinula edodes via di-mon mating. Genetic analysis to fully compatible di-mon mating showed that the monokaryons with rived dikaryon, this showed that a pre-entrance nucleus exists in donor and pre-entrance nucleus mainly dependent on the compatible specificity of B mating-type factor between acceptor and donor nucleus; the higher the specificity, the faster the migration of pre-entrance nucleus.
