Summary
This summary is machine-generated.Two new fungal species, Amphichorda excrementa and Amphichorda kunmingensis, were discovered on animal feces in China. Phylogenetic analysis confirmed their unique genetic makeup, expanding the Amphichorda genus.
Area Of Science
- Mycology
- Fungal Taxonomy
- Biodiversity Research
Background
- The fungal genus Amphichorda, previously in Cordycipitaceae, is now classified under Bionectriaceae.
- Amphichorda species are primarily found on diverse substrates, notably animal feces.
- Yunnan Province in China is a region with significant fungal biodiversity.
Purpose Of The Study
- To identify and describe new species of Amphichorda from Yunnan Province, China.
- To conduct a comprehensive phylogenetic analysis to confirm the novelty of the discovered species.
- To compare the morphological characteristics of the new species with existing Amphichorda species.
Main Methods
- Isolation and cultivation of fungal species from animal feces.
- DNA extraction and sequencing of five genes (nrSSU, nrLSU, tef-1α, rpb1, rpb2) and the ITS region.
- Phylogenetic analysis using the generated sequence data.
- Morphological characterization and comparison.
Main Results
- Two new species, Amphichorda excrementa and Amphichorda kunmingensis, were identified.
- Phylogenetic analyses based on five-gene and ITS data supported the distinctness of the new species.
- Detailed morphological descriptions and comparisons with seven known Amphichorda species were provided.
- Both new species were isolated from animal feces in a park environment.
Conclusions
- The discovery of Amphichorda excrementa and Amphichorda kunmingensis expands the known diversity within the Amphichorda genus.
- The study confirms the Bionectriaceae family's classification for Amphichorda.
- This research contributes to the understanding of fungal biodiversity in China, particularly on coprophilous substrates.

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.
The length of the branches can depict time or the relative amount of change among organisms. For instance, the branch length might indicate the number of amino acid changes in the sequence that underlies the...
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
Allopatric Speciation
In allopatric speciation, gene flow between two populations of the same species is prevented by a geographic...
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.
Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...
