1. THE WONDERS OF
MYCORRHIZAL
FUNGI

2. MYCORRHIZAL FUNGI
Mycorrhizal fungi are a diverse group of soil
microorganisms that form mutually beneficial
symbiotic relationships with the roots of most plants.
These fungi are found in nearly all terrestrial
ecosystems and play a crucial role in nutrient cycling
and plant health.
Mycorrhizal associations have been estimated to
occur in about 80-90% of all plant species, making
them one of the most widespread and essential
components of terrestrial ecosystems.

3. Arbuscular Mycorrhizae (AM): These fungi, also known as
endomycorrhizae, penetrate the root cells of the host plant, forming
branched structures called arbuscules. AM fungi are known to be
associated with approximately 70% of all plant species.
Ectomycorrhizae (ECM): ECM fungi, on the other hand, form a dense
network around the plant root tips, but they do not enter the root cells.
They are typically associated with trees, particularly conifers.
Ericoid Mycorrhizae (ERM): ERM fungi are specialized for plants in the
Ericaceae family, which includes blueberries, heather, and
rhododendrons.
Orchid Mycorrhizae: Orchid mycorrhizae are unique and crucial for
orchid growth. These fungi assist in the germination of orchid seeds and
provide nutrients during the early stages of development.

4. Mycorrhizal symbiosis is a fascinating example of mutualism
in nature. It involves an exchange of resources between the
plant and the fungus.
The plant supplies the mycorrhizal fungus with
carbohydrates produced through photosynthesis, while the
fungus enhances the plant's nutrient and water absorption
capabilities.
This partnership benefits both parties, as the plant gains
access to essential nutrients like phosphorus and nitrogen,
while the fungus receives a source of energy.

5. BENEFITS OF
MYCORRHIZAL FUNGI
The benefits of mycorrhizal fungi extend far beyond
nutrient uptake. They play a crucial role in enhancing plant
growth, health, and ecosystem sustainability.
Improved Nutrient Uptake: Mycorrhizal fungi increase the
surface area available for nutrient absorption by the plant,
particularly phosphorus, which is often limiting in soils.
Enhanced Drought Tolerance: The fungal network acts as a
reservoir, storing water and helping plants withstand
drought conditions.
Disease Resistance: Mycorrhizae can boost a plant's
defense mechanisms, reducing its susceptibility to
diseases and pathogens.

6. ROLE OF MYCORRHIZAE IN
PLANT NUTRITION
Mycorrhizal fungi aid in nutrient acquisition by extending their hyphal
network into the soil, effectively increasing the plant's reach for
nutrients.
They are especially efficient in acquiring phosphorus, which is typically
found in forms that are challenging for plants to access on their own.
This enhanced nutrient uptake results in healthier, more vigorous
plants, ultimately benefiting agricultural and horticultural practices.

7. MYCORRHIZAE AND
SOIL HEALTH
The benefits of mycorrhizal fungi extend far beyond
nutrient uptake. They play a crucial role in enhancing plant
growth, health, and ecosystem sustainability.
Improved Nutrient Uptake: Mycorrhizal fungi increase the
surface area available for nutrient absorption by the plant,
particularly phosphorus, which is often limiting in soils.
Enhanced Drought Tolerance: The fungal network acts as a
reservoir, storing water and helping plants withstand
drought conditions.
Disease Resistance: Mycorrhizae can boost a plant's
defense mechanisms, reducing its susceptibility to
diseases and pathogens.

8. ARBUSCULAR
MYCORRHIZAE
Arbuscular mycorrhizae are perhaps the
most well-studied and widespread type of
mycorrhizal fungi. They have co-evolved
with plants for millions of years.
AM fungi are known for their ability to form
highly branched arbuscules within plant root
cells, increasing the surface area for nutrient
exchange.
They are associated with a diverse range of
plant species, including many crops and
garden plants.

9. ECTOMYCORRHIZAE
Ectomycorrhizal fungi are primarily
associated with trees, especially
conifers and hardwoods.
Unlike AM fungi, they do not penetrate
plant cells. Instead, they form a sheath-
like structure around the root tips,
known as the Hartig net.
ECM fungi are essential for the growth
and health of many forest ecosystems.

10. ERICOID
MYCORRHIZAE
Ericoid mycorrhizal associations are specialized
for plants in the Ericaceae family, which often
grow in acidic and nutrient-poor soils.
These fungi enable Ericaceae plants like
blueberries and heather to thrive in challenging
environments by improving nutrient uptake.

11. ORCHID
MYCORRHIZAE
Orchid mycorrhizae are a fascinating subset
of mycorrhizal fungi that have evolved
unique adaptations to support orchid
growth.
Orchid seeds lack endosperm and are tiny,
making them dependent on specific
mycorrhizal fungi for germination and initial
nutrition.
The relationship between orchids and their
mycorrhizal partners is highly specialized
and often species-specific.

12. MYCORRHIZAL FUNGI
IN AGRICULTURE
In agriculture, mycorrhizal fungi have gained
attention for their potential to improve crop yields
and reduce the need for synthetic fertilizers.
They can enhance nutrient availability to crops,
leading to healthier plants and potentially higher
harvests.
Mycorrhizal inoculants are now commercially
available for farmers looking to harness these
benefits.

13. MYCORRHIZAE &
ENVIRONMENTAL
SUSTAINABILITY
Mycorrhizal fungi play a vital role in
sustainable agriculture and ecosystem
management.
By reducing the reliance on chemical fertilizers,
they contribute to environmentally friendly
farming practices.
Additionally, mycorrhizae contribute to soil
carbon sequestration, aiding in carbon cycle
regulation and climate change mitigation.

14. MYCORRHIZAL
FUNGI RESEARCH
Ongoing research aims to unravel the genetic,
physiological, and ecological aspects of
mycorrhizal fungi.
Scientists use advanced techniques to study
their role in nutrient cycling, plant-fungal
interactions, and ecosystem dynamics.
This research is critical for harnessing the full
potential of mycorrhizal fungi in agriculture
and conservation efforts.

15. MYCORRHIZAE IN
ECOSYSTEMS
Mycorrhizal fungi are keystone species in many
ecosystems, influencing plant community
composition and ecosystem stability.
They facilitate the growth of a wide variety of
plants, including both native and non-native
species.
The presence or absence of mycorrhizal
associations can impact the success of plant
species in a given ecosystem.

16. CHALLENGES IN
MYCORRHIZAL FUNGI
CONSERVATION
The conservation of mycorrhizal fungi faces
challenges related to habitat destruction, land
use changes, and climate change.
Protecting natural habitats where these fungi
thrive is essential for preserving their diversity
and functionality.
