The diagram on the right illustrates that rhizosphere microorganisms like plant-growth-promoting bacteria (PGPB), arbuscular mycorrhizal fungi (AMF), and fungi from the genus Trichoderma spp. can establish beneficial interactions with plants, promoting plant growth and development, increasing the plant defense system against pathogens ...
The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [ 1 ] [ 2 ] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.
The root microbiome (also called rhizosphere microbiome) is the dynamic community of microorganisms associated with plant roots. [1] Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria , fungi , and archaea .
Interactions between the host plant and phyllosphere bacteria have the potential to drive various aspects of host plant physiology. [ 8 ] [ 2 ] [ 9 ] However, as of 2020 knowledge of these bacterial associations in the phyllosphere remains relatively modest, and there is a need to advance fundamental knowledge of phyllosphere microbiome dynamics.
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
The plant microbiome plays key roles in plant health and food production and has received significant attention in recent years. Plants live in association with diverse microbial consortia, referred to as the plant microbiota, living both inside (the endosphere) and outside (the episphere) of plant tissues. They play important roles in the ...
A greater diversity of plants in a soil leads to a greater diversity of microbes in the rhizosphere and furthermore can lead to greater suppression of soil diseases. [9] Management, such as informed crop rotation and soil solarization , can create suppressive soils that naturally suppress pathogens.
Recent studies have investigated the detailed structure of root-associated microbial communities at a continuous fine-scale in other plants, [85] where a microhabitat was divided into four root compartments: endosphere, [75] [86] [87] episphere, [75] rhizosphere, [86] [88] and nonrhizosphere or bulk soil.
