Rhizoplane

from Wikipedia, the free encyclopedia

Rhizoplane refers to a community of extremely metabolically and reproductively active bacteria, including Actinomycetales. This community is in very close contact with the fine roots and is located a few μm near the root surface. The soluble carbohydrates, oligosaccharides, organic acids, enzymes, vitamins and growth substances secreted by the roots support the formation of a specific microflora. The mucilage coat of the root tips consists of liquefiable carbohydrates and acts as a substrate for the microflora near the root. The plant benefits from the mutual exchange of substances with the rhizoplane. It receives additional nutrients that are released by the bacteria. Mycorrhizal fungi act as transmitters. The associated microflora also secrete antibiotic substances, protecting the roots of the plant from specific pests.[1] The rhizoplane is seamlessly followed by the rhizosphere. Rhizoplane and rhizosphere together form the soil root interface[2] (soil root interface).
