Influences of soil acidity and variety of plant on the populations of Rhizobium trifolii found in nodules of Trifolium subterraneum L.

Creator:: Dughri, Muktar H.
Abstract:: Complementary methods of strain identification were sought to delineate the composition of the population of Rhizobium trifolii found in nodules of Trifolium subterraneum L. when exposed to an Abiqua silty clay loam (Cumulic Ultic Haploxeroll) containing a resident population of R. trifolii. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDSPAGE) was...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Characteristics of bradyrhizobium sp. recovered from Oregon soils

Creator:: Cheng, Hsin-hua
Abstract:: Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

Symbiotic characteristics of Rhizobium leguminosarum bv. trifolii recovered from nodules of field-grown Trifolium subterraneum L.

Creator:: Wanjagi, Francis Ndung'u
Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...

Delineation of the composition of an indigenous soil population of Rhizobium meliloti in root nodules of uninoculated field grown Medicago sativa L.

Creator:: Jenkins, Michael B.
Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...

Novel characteristics (Intra and Ex planta) of indigenous serogroups of rhizobium meliloti

Creator:: Busse, Matt D.
Abstract:: This thesis presents novel findings regarding symbiotic, physiological, and antigenic characteristics of representatives from an indigenous soil-borne population of Rhizobium meliloti. Nodules were sampled from 'Vernal', 'Anchor', and 'Saranac' alfalfa, and the isolates analyzed serologically. Rhizobium meliloti serogroup 31 was identified as a dominant nodule occupant, with a greater and...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...
