Difference Between Primary and Secondary Mycelium

这key differencebetween primary and secondary mycelium is that原发性菌丝体从真菌发展sporeswhen they mature and form germ tubes while secondary mycelium forms from sexually compatible菌丝when they conjugate during thesexual reproduction.

基本菌是真正的真菌。这myceliumof basidiomycete fungi undergoes several development changes such as primary, secondary and tertiary stages. Primary mycelium appears during the primary stage while secondary mycelium appears during the secondary stage of their life cycles. Primary mycelium develops from basidiospores. Spores mature and form ag erm tube and develop into the primary mycelium. During sexual reproduction, sexually compatible two types of hyphae conjugate with each other and form the secondary mycelium.

What is Primary Mycelium?

Primary mycelium is the collection of hyphae formed from the germination of haploid basidiospores. Therefore, primary mycelium is generated after the germination of basidiospores of basidiomycetes.

原发性菌丝体由单因子菌丝组成。因此，菌丝体包含一个单倍体核。原发性菌丝体代表生命周期的单因子阶段。原发性菌丝体的菌丝可以结合并形成二级菌丝体。换句话说，兼容交配菌株的菌丝体可以结合并形成次级菌丝体。但是，与二级菌丝体不同，一菌丝不含夹具连接。此外，原发性菌丝体的寿命很短。

What is Secondary Mycelium?

继发性菌丝体是在两种性兼容的基本菌丝真菌结合后发展的菌丝体。性兼容的菌丝被称为加分和减去菌丝类型。

二级菌丝体包含两个单倍体核，一个来自每个父母。因此，二级菌丝体代表了真菌生活周期的硅藻性阶段。二卡罗尼亚阶段不是二倍体。直到孢子产生前不久，两个核一直没有旋转。这个二核阶段是基础菌群生命周期的主要阶段。二级菌丝体产生了一个带有我们称为蘑菇的基础或水果体。Basidiocarp在其帽子下的ill上包含Basidia。

初级和二级菌丝体之间有什么相似之处？

• 原发性和二级菌丝体是在真菌中看到的两种类型的菌丝体。
• 这y are two development changes in the life cycle.
• When two primary mycelia conjugate, secondary mycelium is formed.
• Basidiomycetes fungi produce both primary and secondary mycelia.

What is the Difference Between Primary and Secondary Mycelium?

Primary mycelium is generated from the germination of basidiospores while secondary mycelium is developed from the conjugation of two mating types of primary mycelia. So, this is the key difference between primary and secondary mycelium. Furthermore, the primary mycelium contains one haploid nucleus. Hence, it represents the monokaryotic phase of the life cycle. In contrast, secondary mycelium contains two haploid nuclei one from each parent. It represents the dikaryotic phase of the life cycle. Moreover, it is the dominant stage of the life cycle.

摘要 - 初级与二级菌丝体

Primary mycelium is the haploid or monokaryotic hyphae generated from the germination of basidiospores. Secondary mycelium is the dikaryotic hyphae formed from the conjugation of two mating types of fungi during the sexual reproduction. Therefore, primary mycelium contains one haploid nucleus while secondary mycelium contains two unfused haploid nuclei. Secondary mycelium represents the dominant stage of the life cycle, unlike primary mycelium. Moreover, secondary mycelium has a long life span compared to primary mycelium. Thus, this summarizes the difference between primary and secondary mycelium.
