杂交和后代分析表明，5个深色素弱毒力菌株含有单个核基因，赋予了一类欧洲弱毒力菌株的形态特征，以前称为Jaune Régénéré或Pigmentum。这些单核基因也决定了寄主板栗树的限制性毒性。此类菌株仅来自含dsRNA的菌株，并且可能是细胞质遗传物质整合到核基因组中的结果。
Crossing and progeny analyses showed that five deeply pigmented hypovirulent strains contain single nuclear genes that confer the morphology characteristic of a class of European hypovirulent strains formerly called Jaune Régénéré or Pigmentato. These single nuclear genes also determine restricted virulence in host chestnut trees. Such strains arise only from dsRNA-containing strains and may be the result of integration of cytoplasmic genetic material into the nuclear genome.
