It is revealed that plants affect ecosystem functions through interspecific promotion

Biodiversity strengthens and maintains the functions of ecosystems, which have been confirmed in terrestrial ecosystems such as grasslands, forests, and farmlands
.

However, it is not clear how plant diversity affects ecosystem functions through the interspecific promotion of underground parts

This article is based on a series of research results of the research group in this field over the past 20 years, combined with the latest developments in related fields in the world, and the direct promotion between plants and plants driven by root exudates, signal molecules, and root trait plasticity, as well as plants By influencing the composition of soil microorganisms and animals, and further improving the indirect promotion between plants and plants, the mechanism of the promotion of underground is discussed
.

The occurrence of these direct and indirect promotion effects requires the matching of interaction processes between different plants and between plant and soil organisms, so that promotion can play an important role in the relationship between biodiversity and ecosystem functions

The direct promotion between plants can be mediated by root exudates and signal molecules
.

The results of the research team published in the Proceedings of the National Academy of Sciences of the United States in 2007 and 2016 provide important evidence for this argument

The direct promotion between plants can also be produced by trait plasticity
.

The results of the research group published in the "New Botanist" in 2020 show that the occurrence of interspecific phosphorus promotion requires not only the presence of beneficiary plants with strong phosphorus activating ability in the community, but also the beneficiary plants with weak phosphorus activating ability to pass.

The indirect promotion between plants is mainly produced by the interaction between root system and soil organisms
.

The changes in soil microbial composition and microbial-microbial interaction caused by root exudates can help strengthen the promotion of plants

For ecologists and botanists, how to apply the progress made in the theoretical research of biodiversity to the construction of sustainable ecosystems and the restoration of degraded ecosystems is a major challenge
.

Previous studies have paid more attention to the design of high-yielding communities through the complementarity of resources in time and space.
