Summary
This summary is machine-generated.The rare JinEr mushroom harbors a unique bacterial community, with Delftia and Sphingomonas dominating. Some bacteria show compatibility, aiding potential cultivation enhancements.
Area Of Science
- Fungal-bacterial interactions
- Microbial ecology of macrofungi
- Symbiotic associations in fungi
Background
- The JinEr mushroom (Golden Ear) is a rare edible and medicinal macrofungus.
- It's a symbiotic complex of *Naematelia aurantialba* and *Stereum hirsutum*.
- Microbial interactions within this complex are poorly understood.
Purpose Of The Study
- To analyze the microbial diversity and community structure within JinEr basidiomata.
- To investigate the potential functional roles of the endomycotic bacterial community.
- To understand host-specific selection and interactions with cultivation substrate.
Main Methods
- High-throughput amplicon sequencing for microbial diversity.
- In situ microbial isolation and culture for culturable bacteria.
- Microbial confrontation assays and in vitro co-culture experiments.
Main Results
- JinEr basidiomata are dominated by *Stereum hirsutum* (approx. 80%).
- *Delftia* and *Sphingomonas* are dominant bacterial genera (85.42% of prokaryotic sequences).
- Bacterial diversity differs significantly between basidiomata and substrate, indicating host specificity.
- 140 bacterial isolates were obtained; 8 showed compatible growth, 1 showed antagonism.
Conclusions
- JinEr basidiomata host a specific prokaryotic assemblage with potential symbiotic associations.
- This study advances understanding of microbial ecology in rare fungal complexes.
- A culture repository of associated bacteria was established for future cultivation enhancement.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...
