Influence of soil and rhizosphere actinomycetes on Frankia infection and nitrogenase activity in Alnus rubra Bong

Creator:

Rojas-Melo, Nestor S.

Abstract:

Nodulated roots of young red alder trees and soil samples were collected from a 5 year old clearcut on Mary's Peak, Oregon. Frankia was isolated from root nodules, andactinomycetes from nodules, roots, and soil. A total of 229 pure culture actinomycete isolates were recovered: 131 colonies from root surfaces, 52...

Exploring phylogeny of Rhodococcus fascians isolates using 16S ribosomal DNA sequence analysis

Creator:

Sandberg, Eva Song

Abstract:

Rhodococcus fascians is a Gram-positive, pleiomorphic actinomycete that causes leafy gall formation in a wide range of plant hosts. This particular phytopathogen has been a focus of research at the Oregon State University Plant Clinic, a diagnostic laboratory. Phylogeny of R. fascians isolates obtained from Plant Clinic submissions was determined...
