Mycorrhiza和Coralloid rots之间的差异|比较类似术语之间的差异

这关键区别在菌根和珊瑚的根之间Mycorrhiza是一种在较高植物和真菌之间发生的一种相互关联cycadswhich are in a mutualistic association with nitrogen-fixing蓝细菌。

共生是生活在一起的两种不同物种之间的长期关联。共生关系有三种类型，作为寄生虫，互助和共同主义。互助是一种共生关系，在这种关系中，双方从关系中受益。Mycorrhiza和Coralloid根是两种相互作用的类型。Mycorrhiza是真菌与血管植物根部之间的共同关联。冠状根是含有氮固定蓝细菌的蛋白石根系的特殊类型。

什么是mycorrhiza？

Mycorrhiza is a type of symbiotic relationship that occurs between a fungus and the roots of a higher plant. It is a type of mutualistic association which is beneficial for both partners. In mycorrhiza, both plant and fungus reach benefits from their association. Fungal hyphae penetrate the soil and bring nutrients to the plant. The plant, in turn, assimilates carbohydrates and shares them with the fungus. Hence, it is an ecologically important relationship. Most importantly, when the plant roots do not have access to the nutrients, fungal hyphae can grow several meters and transport water and nutrients, especially nitrogen, phosphorus, potassium to the roots. Hence, nutrient deficiency symptoms are less likely to occur on plants which are in this symbiotic association. About 85% of vascular plants possess endomycorrhizal associations. In addition, fungus protects the plant from root pathogens. Therefore, mycorrhizae are very important associations in the ecosystems.

有两种类型的菌根作为外生菌和内瘤性。Ectomycorrhizae请勿形成杂草和囊泡。同样，它们的菌丝不会穿透植物根的皮质细胞。然而，外生霉菌非常重要，因为它们有助于植物探索土壤中的养分并保护植物根部免受根病原体的影响。在内菌病，真菌菌丝穿透植物根的皮质细胞并形成囊泡和刺刺。内菌病比外生菌骨更常见。来自Ascomycota和basidiomycota的真菌有助于形成外生肌肉关联，而肾小球的真菌有助于形成内瘤性。

什么是珊瑚根？

珊瑚根是苏铁的专门共生根。仙女与蓝细菌或蓝色绿藻形成这种相互关系。因此，冠状根是一种特殊的根系，可容纳共生氮固定蓝细菌，尤其是阿纳巴纳。这些根是负向地性的。苏铁植物是the only members of gymnosperms that are capable of forming this new association with cyanobionts. In this association, cyanobacteria fix nitrogen for their host plant cycad. Cyanobacteria fix atmospheric N₂into useful forms of nitrogen.

珊瑚根在土壤表面下生长。因此，蓝细菌无法进行光合作用。在居住在根部的过程中，蓝细菌可获得保护，稳定的环境和营养，尤其是植物的碳。该植物接收固定的氮。两种植物（赛车）和蓝细菌（阿纳巴纳) benefit from their mutualistic association.Anabaena CicadaeorNostoc cicadaeare the two cyanobacteria identified commonly in coralloid roots of cycads.
