Seedborne fusarium and root colonization of container-grown douglas-fir seedlings
The role of seedborne Fusarium in root colonization of container-grown Douglas-fir seedlings was studied in two coastal Douglas-fir seedlots; one contaminated with Fusarium and the other with minimal Fusarium. Seedlots were treated using either a standing water imbibition, or a running water …

Effects of soil pH and soil water potential on arbuscular-mycorrhizal fungal colonization of soybean
… of arbuscular-mycorrhizal (AM) fungal colonization of plants are highly affected by the conditions in the growth medium. The effect of extreme soil pH and moisture conditions on AM fungal development and plant-growth enhancement has been well documented independently. However, the soil …

IDENTIFICATION OF COMMON MECHANISMS TO INTRACELLULARLY ACCOMMODATE BENEFICIAL OR PATHOGENIC FUNGI IN RICE
… Despite their opposing roles, their respective colonization of rice roots share similarities at the transcriptional and morphological level in host cells. This study investigates potential common genetic mechanisms for the intracellular accommodation of these fungi in rice roots. The functional …

DISCLOSING THE ROLE OF ROOT EXUDATES IN MODULATING THE INTERACTION BETWEEN PLANT AND XENOBIOTIC DEGRADING BACTERIA
Positive interactions between plants and root-associated bacteria are fundamental to maintain the homeostasis of the holobiont, especially upon environmental stresses. This crosstalk is mediated by root exudates (REs), including plant secondary metabolites, that are released by the plant as a …

Effects of Heterodera Glycines Population Densities on Fusarium Solani F. Sp. Glycines Colonization of Soybean Roots and Development of Sudden Death Syndrome
Estimation of root colonization by Fsg with the plating bioassay was difficult and the results were often unsatisfactory in these experiments. Therefore, an alternative method was explored, relative quantification with real-time quantitative PCR (QPCR), to estimate fungal colonization of soybean …

Isoflavonoid induction and nitrogen assimilation in AM colonized red clover
… set forth were to determine the impact of AM colonization and/or rhizobial inoculation in red clover on the: (1) growth parameters; (2) nitrogen assimilation, via the activity of glutamine synthetase (GS, E.C. 6.3.1.2), total N content and soluble protein concentration; (3) contents of …

Effect of soilpH and temperature on the biological control of Rhizoctonia solani by Bacillus megaterium and Trichoderma harzianum
The root rot and seedling blight of soybean, caused by Rhizoctonia solani isolate 2B-12 and controlled by Bacillus megaterium and Trichoderma harzianum, was the disease/biocontrol model used for a systematic study of the effect of soil pH and temperature on the biological control of soilborne plant …

Characterization of tomato root-endophytic fungi and analysis of their effects on plant development, on fruit yield and quality and on interaction with the pathogen Verticillium dahliae
… endophytes are able to colonize internally roots without causing visible disease symptoms establishing neutral or mutualistic associations with plants. These fungi known as non-clavicipitaceous endophytes have a broad host range of monocot and eudicot plants and are highly diverse. Some of …

Silver Nanoparticles and the Plant-Associating Abilities of Rhizobiaceae Bacteria
… with AgNPs (50 ppm). A significant decrease in root colonization of Triticum aestivum roots by A. brasilense was observed as AgNP treatment concentrations increased. Although some of the experiments could not be completed, taken together, these experiments and the research reported herein …

Asymptomatic infections of Euphorbia lathyris by Macrophomina phaseolina.
… and the number of infection sites per cm of root increased significantly (P < 0.05) over each growing season and were not related to rhizosphere soil populations of M. phaseolina (P > 0.05). The distribution of infection sites along the tap root over both growing seasons remained the same in …

Effects of Root Characteristics and Deep Tillage on the Development of Sudden Death Syndrome in Soybean
… not always correlate well with infection on the root system or with reductions in yield. A combination of root and foliar symptom severity ratings would provide more information on disease resistance. Yet, it is unknown whether physical mechanisms exist by which the root system of the soybean …

Influence of Penicillium simplicissimum (Oud.) Thom and Penicillium citrinum Thom on growth, chemical composition and root exudation of axenic marigold
… plant containers, designed for collecting root exudates, inside sterile gnotobiotic flexible plastic isolators. Plant roots were treated with washed conidiospores of Penicillium simplicissimum (Oud.) Thom (7 to 8 x 10⁶ per plant) or Penicillium citrinum Thom (4 x 10⁶ conidiospores per …

The relationship between dominant forest mycorrhizal type and the belowground mycobiome of the sugar maple and eastern hemlock
… of dominant forest mycorrhizal types on soil and root (1) fungal diversity and community composition, (2) taxonomic and functional groupings, as well as (3) arbuscular mycorrhizal colonization along four gradients of forest mycorrhizal types. To do this, 435 seedlings of the sugar maple (Acer …

The Role Of Soil Microorganisms In The Resistance Of Giant Ragweed, Horseweed, And Common Lambsquarters To Glyphosate
… was demonstrated to be strongly influenced by root invading soil-borne microorganisms. However, this interaction among plants, glyphosate, and soil microorganisms has only been studied in a number of crop plants, but not in weed species. This is surprising since the soil biotic environment has …

Effects of Seed Applied Fungicide on Arbuscular Mycorrhizal Colonization of South Dakota Cultivars of Oat, Soybean, and Corn
… of cultures isolated from agricultural soils. Roots were cleared, stained, and evaluated for the extent of mycorrhizal root colonization. Plant biomass, height, growth stage, and tissue analysis were measured to evaluate differences between both crop varieties and seed treatments.<br />In oat …
