rhizosphere


Also found in: Dictionary, Encyclopedia, Wikipedia.

rhizosphere

the particular area immediately surrounding the roots of plants in which their exudations affect the surrounding microbial flora. Many exudations are nutrients which the microorganisms utilize and include carbohydrates, vitamins and amino acids. Conversely, the plant roots may take up minerals released by the microorganisms. Bacteria may be present in the rhizosphere in numbers fifty times greater than in surrounding soil. Gram-negative rods predominate whereas Gram-positive forms are less common than in the surrounding soil. Fungi are usually present in the rhizosphere in similar quantities to those in the surrounding soil, though some plants encourage particular forms.

2010) also showed that application of bio-organic fertilizer formulated with Bacillus subtilis biological control agent significantly improved fungal population composition in rhizosphere soils and effectively controlled cotton verticillium wilt.

2017) the soil at Nova Esperanga, a rural farming community located within the limit of Manaus, AM, Brazil, where the Coriandrum sativum (coriander) rhizosphere soil samples were collected, presents a sandy texture and at 10-20 cm depth is considered fertile.
Several attempts have been made to produce AMF spores axenically, but pot culture methods have often obtained contaminated material along with plant and other debris, in this study, we aimed to determine whether different LED combinations could induce AMF colonization in bahiagrass and millet roots, and form new spores in the rhizosphere by using a 'glass beads' pot method.
The sampling design of the aboveground biomass was identical to that of the rhizosphere soil - the same plants were used for leaves and rhizosphere soil sampling.
reniformis being found in the soil collected from the soursop rhizosphere, it cannot be confirmed as a host plant of this species given that this nematode is a sedentary semi-endoparasite (FORTUNER, 1987), which may be found in the radicular system of these plants.
Over the last two years, VBC has made sizeable commitments to rhizosphere technologies including the acquisition of Mycorrhizal Applications, LLC (MA) and several licensing and research agreements designed to accelerate its root zone portfolio.
