Plant-fungal interspecific interactions drive many key ecosystem properties and processes, such as litter degradation, soil carbon sequestration, and mycorrhizal symbiosis
.
However, differences between aboveground and subsurface habitats in plant-fungal interspecific interactions at large spatial scales have been seldom reported
.
Recently, the research group of Chu Haiyan of the Nanjing Institute of Soil Science, Chinese Academy of Sciences, and a number of scientific researchers inside and outside the United Nations published a report entitled "China Life Sciences Plant and fungal species interactions differ between The research paper "aboveground and belowground habitats in mountain forests of eastern China" reveals the plant-fungal interspecific interaction patterns
between aboveground and underground habitats at the large-scale scale (>2000 km) of forests in eastern China.
In the previous study, Chu Haiyan's group quantitatively revealed the significant influence of plant phylogenetic characteristics on the spatial distribution of soil fungal communities in the same regional range, and pointed out that there was a dependence of functional taxa in this influence (ISME J 2019).
。 In this study, the authors first compared the relative effects of climate, soil, plants (including plant species, plant phylogenetic characteristics and plant functional traits) and spatial factors on the biogeographic distribution of soil fungi and intraleaf fungi, and found that plant phylogenetic characteristics were the strongest drivers of intraleaf fungal community composition, explaining 19.
1% of community variation.
Plant phylogenetic characteristics, soil properties and climatic factors explained the spatial variation
of soil fungal communities by 9.
2%, 9.
0% and 8.
7%, respectively.
The theory and method of two-dimensional network were further adopted to reveal the topology of plant-fungal network that was completely different between aboveground and underground habitats, and it was found that compared with the plant-soil fungal two-dimensional network, the two-dimensional network of plant-leaf fungi showed higher specialization, modularity and robustness (resistance to species loss), but the complexity of the aboveground two-dimensional network structure was significantly smaller than that of the underground two-dimensional network
.
In addition, the specialized combination of host plants and fungi, as well as network-key species, have shown significant differences
between aboveground and subsurface habitats in forests.
This study provides a new reference
for in-depth understanding of the mechanism of transboundary coexistence and diversity maintenance between plant and fungal species at large spatial scales.
Comparison of structure and characteristic parameters of plant-fungal networks in aboveground and underground habitats of forests, Associate Professor Yang Teng of Nanjing Institute of Soil Science, Chinese Academy of Sciences is the first author of the paper, and researcher Chu Haiyan is the corresponding author
