Comparative gibberellin relationships in tall and dwarf peas (Pisum sativum L.)

Creator:: Anderson, James David
Abstract:: Experiments were performed to determine whether a direct correlation exists between the growth rates of tall and dwarf peas grown either in the light or in the dark and endogenous gibberellin (GA) content. Three separate but related experimental approaches were utilized: (1) the determination of possible qualitative and /or quantitative...

Role of GacSA Two-component System and Bacterial Surface Attachment in Pseudomonas syringae Virulence

Creator:: O'Malley, Megan R.
Abstract:: Pseudomonas syringae are plant pathogenic bacteria that cause disease by rapidly multiplying within the aboveground tissues of host plants. Growth of P. syringae within plant host tissues requires the disarmament of host immune defenses that limit microbial growth. To combat host defenses, P. syringae deploys a type III secretion system...

Characterization of a bacterial agglutinin from legumes

Creator:: Jasalavich, Claudia Ann
Abstract:: Leaves of Phaseolus vulgaris cv. 'Dark Red Kidney' and cv. 'Red Mexican U. I. 31', Phaseolus lunatus cv. 'Fordhook Bush 242', Phaseolus mungo cv. 'Berken', and Glycine max cv. 'Wilkin' have been shown to contain a factor which consistently agglutinated the saprophyte Pseudomonas putida; another saprophyte Pseudomonas fluorescens was agglutinated...

Taxonomy and host specificity of the genus Agrobacterium

Creator:: Anderson, Arthur Robert
Abstract:: One hundred seventy-eight Agrobacterium isolates, 120 United States (U.S.), 26 Australian and 32 of miscellaneous origin, were characterized for their reactions to 20 biochemical and physiological tests. Isolate pathogenicity and degree of host specificity, utilization of nopaline and octopine, and sensitivity to agrocin-84 also were determined. The U.S. isolates were...

Risk of Exposure to Eastern Equine Encephalomyelitis Virus Increases with the Density of Northern Cardinals

Creator:: Estep, Laura K., McClure, Christopher J. W., Vander Kelen, Patrick, Burkett-Cadena, Nathan D., Sickerman, Stephen, Hernandez, José, Jinright, Joseph, Hunt, Brenda, Lusk, John, Hoover, Victor, Armstrong, Keith, Stark, Lillian M., Hill, Geoffrey E., and Unnasch, Thomas R.
Abstract:: For a variety of infectious diseases, the richness of the community of potential host species has emerged as an important factor in pathogen transmission, whereby a higher richness of host species is associated with a lowered disease risk. The proposed mechanism driving this pattern is an increased likelihood in species-rich...

Reevaluation of systematic relationships in Triticum L. and Aegilops L. based on comparative morphological and anatomical investigations of dispersal mechanisms

Creator:: Morrison, Laura A.
Abstract:: Comparative morphological and anatomical studies of the dispersal mechanisms characterizing the wheat complex (Triticum L. and Aegilops L.) have documented patterns of adaptive radiation which may have significance for evolutionary relationships. These patterns, which form an array of diverse types of diaspores among the diploid taxa, appear conceptually to have...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...
