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.
Photomicrograph of the microflora Streptococcus pyogenes bacteria, 900x mag. In microbiology, collective bacteria and other microorganisms in a host are historically known as flora. Although microflora is commonly used, the term microbiota is becoming more common as microflora is a misnomer. Flora pertains to the Kingdom Plantae.
Numerous microbial antagonists, including yeasts and bacteria, are isolated from diverse environments such as soil, plants, compost, and oceans for their potential to control plant diseases. For example, endophyte microorganisms found inside guarana seeds and rhizospheric soil have shown their ability to fight harmful pathogens, making them ...
Plant pathogens, organisms that cause infectious plant diseases, include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. [2] In most plant pathosystems, virulence depends on hydrolases and enzymes that degrade the cell wall.
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 ...
Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli. Erwinia uses cell wall–degrading enzymes to cause soft rot.
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.
