Prior blood feeding effects on susceptibility of Anopheles gambiae (Diptera: Culicidae) to infection with cultured Plasmodium falciparum (Haemosporida: Plasmodiidae)
(Oxford University Press (OUP), 1994)
We examined the relative susceptibilities of Anopheles gambiae Giles of different physiological ages to infection with cultured Plasmodium falciparum (Welch). Cohorts of mosquitoes were divided into three groups; one was ...
Evidence for phage-mediated gene transfer among Pseudomonas aeruginosa strains on the phylloplane
(American Society for Microbiology, 1994-02)
As the use of genetically engineered microorganisms for agricultural tasks becomes more frequent, the ability of bacteria to exchange genetic material in the agricultural setting must be assessed. Transduction (bacterial ...
Identification and relatedness of coronatine-producing Pseudomonas syringae pathovars by PCR analysis and sequence determination of the amplification products
(American Society for Microbiology, 1994-08)
Production of the chlorosis-inducing phytotoxin coronatine in the Pseudomonas syringae pathovars atropurpurea, glycinea, maculicola, morsprunorum, and tomato has been previously reported. DNA hybridization studies previously ...
Genetic and plasmid diversity within natural populations of Pseudomonas syringae with various exposures to copper and streptomycin bactericides
(American Society for Microbiology, 1994-12)
We examined the genetic and plasmid diversity within natural populations of Pseudomonas syringae isolated from three ornamental pear nurseries in eastern Oklahoma. The bactericide spray regimen differed at each nursery; ...
Disruption of morphogenesis and transformation of the suspensor in abnormal suspensor mutants of Arabidopsis
(Company of Biologists, 1994)
The suspensor is the first differentiated structure produced during plant embryogenesis. In most angiosperms, the suspensor functions early in development to provide nutrients and growth regulators to the embryo proper. ...
Sporogonic development of cultured Plasmodium falciparum in six species of laboratory-reared Anopheles mosquitoes
(American Society of Tropical Medicine and Hygiene, 1994)
Sporogonic development of cultured Plasmodium falciparum was compared in six species of Anopheles mosquitoes. A reference species, A. gambiae, was selected as the standard for comparison. Estimates of absolute densities ...
Plasmodium falciparum: The population structure of mature gametocyte cultures has little effect on their innate fertility
(Elsevier BV, 1994)
In vitro cultured Plasmodium falciparum gametocytes were fed to Anopheles gambiae (G3) mosquitoes to identify parasite population characteristics useful for predicting successful mosquito infections. Parameters were collected ...
Exflagellation responses of cultured Plasmodium falciparum (Haemosporida: Plasmodiidae) gametocytes to human sera and midguts of anopheline mosquitoes (Diptera: Culicidae)
(Oxford University Press (OUP), 1994)
The process of exflagellation was quantified for cultured Plasmodium falciparum gametocytes exposed to human sera and midgut homogenates from six vector species of Anopheles mosquitoes. Neither serum factors related to ...
Effect of risk aversion on feeder cattle prices
(Cambridge University Press, 1994-12)
This paper determines the effects of cattle feeders' risk aversion on feeder cattle prices using pen data of Kansas feedlots. Higher profit risk results in lower feeder cattle prices. The elasticity of feeder cattle price ...
Biosynthetic gene cluster for coronamic acid, an ethylcyclopropyl amino acid, contains genes homologous to amino acid-activating enzymes and thioesterases
(American Society for Microbiology, 1994-12)
Coronamic acid (CMA), an ethylcyclopropyl amino acid derived from isoleucine, functions as an intermediate in the biosynthesis of coronatine, a chlorosis-inducing phytotoxin produced by Pseudomonas syringae pv. glycinea ...
