食用菌的不同性别菌丝能否结合,主要取决于菌丝的不亲和因子(基因)。根据不亲和因子的情况,可将食用菌划分为不同的交配系统。不亲和性(incompatibility),又叫不相容性。当不同性别的菌丝相遇时,如果它们是亲和的,就发生质配、核配和减数分裂。如果是不亲和的就不发生结合。这种不亲和性和性别有密切关系,但又有区别。性别是指真菌的雌雄性器官和雌雄性细胞。 Edible fungi different sex mycelium can be combined, mainly depends on the mycelium of non-affinity factor (gene). According to the situation of non-affinity factor, edible mushrooms can be divided into different mating systems. Incompatibility, also known as incompatibility. When different gender mycelium meet, if they are compatible, the occurrence of mass distribution, nuclear distribution and meiosis. If it is not affinity will not occur. This lack of affinity and gender are closely related, but different. Sex refers to the fungal male and female organs and male and female cells.
