核体

In part of edible fungi, two different nuclei in heterokaryon are generally consided to distribute evenly to all of colony through clamp connection, and the ratio of two nuclei should be 1:1. But other hypothesis was demurrable according aberrancy of nucleus ratio during monokaryotization of oidiospore and protoplast in F. velutipes. My experiment was constituted of two parts.

在部分食用菌中，一般认为异核体菌丝通过锁状联合这一细胞结构将两种核均匀分布到全部菌落，异核体中两种核的数量比例应该是1：1的关系；但金针菇原生质体单核化和粉孢子单核化过程中发生的核偏离的研究表明，异核体菌丝两种核的数量比例可能不是1：1的关系。

Generally speaking, the reaction types involvingα-oxoketene--acetals mainly include the regioselective addition-aromatization with organometallic reagents, conjugate addition-cyclization with nitrogen nucleophilicspecies, nucleophilic reactions ofα-carbon, acting as odorless dithiol equivalentsin thioacetalization, Michael additions and [5+1] annulation, as well as the synthetic applications based on the above reactions.

一般来说，基于α-羰基二硫缩烯酮化学的反应主要为：与金属有机试剂的选择性加成反应，与氮亲核体的共轭加成反应，α-碳原子的亲核性及相关反应，烷硫基作为硫醇的替代试剂的应用，α-羰基二硫缩烯酮在碳环、杂环化合物合成中的应用等。

Some of them undergone sustained division at a density as low as 102/ml or even in a single heterokaryon culture.

培养24—48小时后用稀释法挑选出异核体，部份异核体可在低密度(10~2/ml)甚至单细胞条件下持续分裂。
