Rhizoplane fibrils in wheat: demonstration and derivation
Science (New York, N.Y.)
|September 20, 1974
Summary
Wheat roots exude fine, curved fibrils into the soil. These extracellular fibrils, 3-10 nm in diameter, associate with microbes and soil particles in the rhizosphere.
Area of Science:
- Plant biology
- Soil science
- Microbiology
Background:
- The rhizosphere is a dynamic interface between plant roots and soil.
- Understanding root exudates is crucial for soil health and plant-microbe interactions.
Purpose of the Study:
- To characterize the extracellular fibrils originating from wheat roots.
- To investigate the association of these fibrils with the rhizosphere environment.
Main Methods:
- Microscopic examination of wheat root rhizoplane.
- Analysis of fibril morphology and diameter.
- Observation of fibril association with microbial cells and soil particles.
Main Results:
- Extracellular fibrils, 3-10 nm in diameter, were observed extending from the wheat root rhizoplane.
- These fine, curved fibrils form aggregates within the rhizosphere.
- Fibril aggregates were found to be closely associated with microbial cells and soil particles.
Conclusions:
- Wheat roots produce extracellular fibrils as part of their rhizoplane activity.
- These fibrils play a role in the structural organization of the rhizosphere.
- The association of fibrils with microbes suggests a potential role in plant-microbe interactions or soil aggregation.

03:25Chemistry of Carbohydrates
Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...
02:21Globular and Fibrous Proteins
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

01:34Introduction to Carbohydrates
Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...
00:55Fibrous Proteins
Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
