What is rhizosphere and phyllosphere?
The key difference between rhizosphere and phyllosphere is that rhizosphere is the region of soil surrounding the plant roots, which is under the influence of root exudates and associated microorganisms, while phyllosphere is the surface of the above-ground plant parts that provide habitat for the microorganisms.
What are rhizosphere microorganisms?
The rhizosphere is a group of organisms associated to plants that are also essential to their metabolism. They are found in synergism with plant roots and are known as rhizosphere microorganisms.
Who coined the term phyllosphere?
The term “Phyllosphere” was coined by the Dutch Microbiologist Ruinen. The leaf surface has been termed as Phylloplane and the zone on leaves inhabited by the microorganisms as Phyllosphere (Figure 10.7). In forest vegetation, thick microbial epiphytic associations exist on leaves.
What is microbial bio control?
Microbial biological control agents (MBCAs) are applied to crops for biological control of plant pathogens where they act via a range of modes of action. Some MBCAs interact with plants by inducing resistance or priming plants without any direct interaction with the targeted pathogen.
What is phyllosphere Slideshare?
phyllosphere is a dynamic rapidly changing area surrounding the germinating seed. there are two categories of microbes one is positively enhancing and negatively reducing the plant yield.
What is meant by rhizosphere?
The rhizosphere is the narrow region of soil or substrate that is directly influenced by root secretions and associated soil microorganisms known as the root microbiome. The rhizosphere also provides space to produce allelochemicals to control neighbours and relatives.
What is plant rhizosphere?
Rhizosphere also known as the microbe storehouse is the soil zone surrounding the plant roots where the biological and chemical features of the soil are influenced by the roots. The rhizosphere is coined more than hundred years ago by Hiltner in 1904.
What is Rhizospheric effect?
Rhizosphere effects (REs) are defined as biological, chemical, and physical changes in soils that occur because of root exudates and rhizodeposition2,3. Moreover, plants and microorganisms release exudates, which improve the soil environment and provide food for animals and microbes in the soil2,4,5.
What is meant by microbial activity?
Microbial Activity Overview Microbial activity can be determined by trapping carbon dioxide (CO2) evolved from soil as the microbial biomass actively decompose soil organic matter and fresh plant residues.
What is biological and biological control agents?
A biological control agent is an organism, such as an insect or plant disease, that is used to control a pest species. The risk analyses are based upon an initial submission for release of a biological control agent, which contains the results of host specificity testing.
What is a phylloplane fungi?
Phylloplane fungi are the mycota growing or the surface of leaves. There are two groups of phylloplane fungi: residents and casuals. Residents can multiply on the surface of healthy leaves without noticeably affecting the host. Whereas, casuals land on the leaf surface but cannot grow.

What does the term phyllosphere mean in microbiology?
Freebase(0.00 / 0 votes)Rate this definition: Phyllosphere. The phyllosphere is a term used in microbiology to refer to leaf surfaces or total above-ground surfaces of a plant as a habitat for microorganisms. The below-ground microbial habitats are referred to as the rhizosphere and laimosphere, respectively.
How does the phyllosphere affect the host plant?
Some are beneficial to the plant, others function as plant pathogens and may damage the host plant or even kill it. The leaf surface, or phyllosphere, harbours a microbiome comprising diverse communities of bacteria, archaea, fungi, algae and viruses.
How is the phyllosphere different from the rhizosphere?
Leaves constitute a huge microbial habitat with larger surface areas and diverse microbial communities. The Phyllosphere area has comparatively less microbial number than the rhizosphere as the parts of the phyllosphere is hydrophobic and covered with wax that limits the exudates produced by the parts.
Why is it important to study the phyllosphere?
Research into the characteristics of microbial life in the phyllosphere is of great commercial importance to the agricultural industry for two reasons. First, understanding the survival of plant disease-causing bacteria and fungi is vital for developing new ways to control their spread.
