Partial characterization of the P4 pathotype of pea seedborne mosaic virus

Creator:: Kohnen, Paul D.
Abstract:: Biological, serological, and molecular characteristics of the P4 pathotype of pea seedborne mosaic potyvirus (PSbMV) were investigated. The characterization allowed P4 to be differentiated from other pathotypes of the same virus. P4 was distinguished from P1 on the basis of host symptomatology. It induced varied, but often distinctive symptoms in...

Qualitative changes in cytoplasmic proteins in plants treated with plant growth regulating chemicals

Creator:: Norris, L. A.
Abstract:: This thesis concerns the alteration of the course of selective protein synthesis and morphogenesis in plants treated with growth regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings (Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused inhibition of epicotyl and primary root elongation and proliferation of massed lateral...

Cytokinin production by Agrobacterium tumefaciens

Creator:: Kaiss-Chapman, Richard Wilkinson
Abstract:: Certain plant-associated prokaryotes such as Corynebacteriurn fascians and Agrobacterium tumefaciens are known to produce substantial levels of cytokinins. In view of the fragmentary and presumptive evidence available on the quantitative and qualitative levels of cytokinins produced by A. tumefaciens, it was decided to conduct a study of the cytokinins produced...

Occurrence, transmission, and properties of strains of cucumber mosaic virus that are seed-transmitted in Phaseolus vulgaris

Creator:: Davis, Robert Francis
Abstract:: A survey of major bean (Phaseolus vulgaris) breeding programs and seed producing areas in Idaho, Washington, and Oregon was conducted to determine the occurrence of cucumber mosaic virus (CMV), recently reported to be seedborne in beans. Some 259 plants, sampled from breeding lines of diverse germplasm, were found by enzyme-linked...

Evaluation of hop (Humulus lupulus L.) protoplast inoculation with Prunus necrotic ringspot virus

Creator:: Jochimsen, Kenneth N.
Abstract:: Hop tissue (Humulus lupulus L.) was grown in vitro in callus, suspension, and protoplast cultures. Medium components were evaluated for optimal callus growth. Solid Murashige and Skoog (MS) medium with picloram at 1.5 uM, 6-benzylaminopurine (BAP) at 10 uM, 1 g/1 casein hydrolysate, and 100 mg/1 citric acid induced white,...

Genomic comparisons of seed-transmissible and non-seed-transmissible strains of cucumber mosaic virus

Creator:: Ried, Jeffrey L.
Abstract:: A sensitive assay for the analysis of contaminating segments in pseudorecombinants constructed from a seed-transmissible (CVM-Pg) and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic virus was developed using partial RNase T₁ digestion. Isolated genomic RNA segments produced unique digestion patterns when 3'- end labeled, treated with RNase T₁, and subjected...

Serological and molecular approaches for distinguishing bean common mosaic and bean common mosaic necrosis potyviruses and their respective pathogroups

Creator:: Xu, Ling, 1963-
Abstract:: Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 recognized BCMV and BCMNV isolates were tested against the two antisera by antigen-coated plate (ACP) ELISA and double antibody sandwich (DAS) ELISA....

Interactions between pea seed-borne mosaic virus pathotype 1 and Pisum sativum resistance gene sbm-1

Creator:: Keller, Karen E.
Abstract:: Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...
