|February 14, 2019
Summary
Researchers identified effective arbuscular mycorrhizal (AM) fungi from Crimean Steppe soils. These AM fungi, primarily from the Rhizophagus genus, form beneficial symbiotic relationships with Sorghum sudanense plants.
Area of Science:
- Soil Microbiology
- Plant Pathology
- Mycology
Background:
- Arbuscular mycorrhizal (AM) fungi are crucial for plant health and soil ecosystems.
- Understanding AM fungal diversity and effectiveness in specific environments like the Crimean Steppe is vital for agricultural applications.
Purpose of the Study:
- To isolate and identify effective arbuscular mycorrhizal (AM) fungi from Crimean Steppe soils.
- To characterize the symbiotic associations formed by these fungi with Sorghum sudanense.
Main Methods:
- Selection of AM fungi based on morphological characteristics of Sorghum sudanense root colonization.
- Analysis of spore morphology and surface appearance for preliminary identification.
- Molecular identification techniques to confirm fungal species and genera.
Main Results:
- Six effective AM fungal associations (P3, P5, S1, S3, S8, S9) were identified.
- AM-fungi formed Arum-type symbiosis with well-established spores specific to each association.
- Morphological and molecular data identified associations P3, P5, S1, S3, S8, and S9 as belonging to the Rhizophagus genus, and association S1 to the Funneliformis genus.
Conclusions:
- The study successfully identified and characterized several effective AM fungal strains from the Crimean Steppe.
- Rhizophagus and Funneliformis genera represent key AM fungal players in this ecosystem, forming effective symbiotic relationships with Sorghum sudanense.

02:11The Roles of Bacteria and Fungi in Plant Nutrition
47.3K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

01:29Overview of Fungi
1.7K
Fungi are a diverse group of eukaryotes more closely related to animals than other eukaryotes. Fungal cell walls comprise chitin, a polysaccharide that provides structural strength, and glucans, which contribute to flexibility and integrity. Other polysaccharides, such as mannans and galactosans, may supplement or replace chitin in some fungi. These adaptations, along with their preference for acidic environments and tolerance for high osmotic pressure, enable fungi to thrive in various...

01:21Association Areas of the Cortex
9.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
