Abstract |
Plants rooted in soil have intimate associations with a diverse
array of soil microorganisms. While the microbial diversity
of soil is enormous, the predominant bacterial phyla
associated with plants include Actinobacteria, Bacteroidetes,
Firmicutes, Proteobacteria, and Verrucomicrobia. Plants supply
nutrient niches for microbes, and microbes support plant
functions such as plant growth, development, and stress tolerance.
The interdependent interaction between the host plant
and its microbes sculpts the plant microbiota. Plant and microbiome
interactions are a good model system for understanding
the traits in eukaryotic organisms from a holobiont
perspective. The holobiont concept of plants, as a consequence
of co-evolution of plant host and microbiota, treats
plants as a discrete ecological unit assembled with their microbiota.
Dissection of plant-microbiome interactions is highly
complicated; however, some reductionist approaches are useful,
such as the synthetic community method in a gnotobiotic
system. Deciphering the interactions between plant and microbiome
by this reductionist approach could lead to better
elucidation of the functions of microbiota in plants. In addition,
analysis of microbial communities’ interactions would
further enhance our understanding of coordinated plant microbiota
functions. Ultimately, better understanding of plantmicrobiome
interactions could be translated to improvements
in plant productivity. |
