Cytoplasmic Male Sterility And Intergrafts Between Lycopersicon Esculentum And Solanum Pennellii Corr., W. R. Andersen

Journal of the Minnesota Academy of Science

Attempts to transmit cytoplasmic male sterility through intergrafts between Lycopersicon esculenfum and Solanum pennellii have been unsuccessful. This implies that in these materials, the factor conditioning cytoplasmic male sterility is noninfective. The results of this study and other similar studies by other workers suggest the possibility that grafting might be used as a tool in the classification of cytoplasmic factors affecting mole sterility in plants.

An Estimate Of Winter Utilization Of The Cedar Creek Natural History Area By The White-Tailed Deer, L. D. Frenzel Jr.

Journal of the Minnesota Academy of Science

Estimates of utilization of the Cedar Creek Natural History Area by the white-toiled deer (Odocoileus virginianus borealis) during the winters of 1963 and 1964 were mode using the deer-drive method. The 1964 estimate is considered the more realistic index of winter utilization by deer of the area because of increased efficiency of the drive, weather conditions favoring deer-drive technics, and agreement with results of pellet-count studies mode independently on the area.

Variations In Porphyrin Content In Root Nodules, Marie H. Berg

Journal of the Minnesota Academy of Science

The root nodules of a series of legumes were investigated with and without inoculum in sterilized growing material as well as in open soil to find plants that synthesize extractable amounts of porphyrins. These experiments were a preliminary study toward the investigation of the influence of heavy metal salts on the increased production of porphyrins.

Experimental Studies On Habitat Preference And Thermoregulation Of Bufo Americanus, B. Hemiophrys And B. Cognatus, John R. Tester, A. Parker, Donald B. Siniff

Journal of the Minnesota Academy of Science

This paper reports on responses lo habitat and thermoregulotion exhibited by three species of toads, Bufo omericanus, B. hemiophrys and 8. cognalus, under artificial conditions. The response of the toads to sparse, medium, and dense vegetative cover was investigated by establishing artificial cover types in a sheet-metal enclosure. Each of the three species spent more time in the dense cover than i11 sparse or medium cover. A second experiment to determine if the toads would be attracted by odor to samples of mud, water, and vegetation from their respective ranges suggested that the toads moved randomly to the habitat samples. …

A Review Of Characters Used In The Identification Of North Central States' Sitona Germar (Coleoptera, Curculionidae)., Valerie J. Fridrich

Chemistry Faculty Publications

Until the discovery of the major product of catecholamine n1etabolism, vanillylmandelic acid (VMA), by Annstrong in 1957 (1), biochemical studies of epinephrine and norepinephrine metabolism were dependent upon determination of the small quantities of these materials excreted unchanged in the urine. The methods designed to measure VMA have proved adequate to detect the gross abnormalities in metabolism usually associated with catecholamine-producing tumors (2-7), but more exact procedures are required for quantitative metabolic studies. Present spectrophotometric and electrophoretic methods are nonspecific in that they yield values for VMA that are higher than those obtained by chromatographic and isotope dilution techniques (5). …

A Model For The Chloroplast: A Study Of The Photochemical And Spectral Properties Of Pheophytin A Adsorbed To The Surface Of Small Particles, Richard Andrew Cellarius

Student Theses and Dissertations

One of the major problems in the study of photosynthesis is understanding the role which the structure of the photosynthetic apparatus has in influencing the nature and efficiency of the photochemical electron-transfer reactions of chlorophyll. This research has involved the study of a simple model for the chloroplast with the purpose of gaining some insight into this problem. It is known that chlorophyll and related molecules will photosensitize oxidation-reduction reactions both in solution and in the adsorbed or colloidal state. The model chosen as being most closely related to chlorophyll in vivo has the pigment adsorbed to the surface of …

The Application Of A Reporter Group To Α-Chymotrypsin, Merrill Burr Hille

Student Theses and Dissertations

A reporter group method was developed in order to obtain information about small changes in the environment at specific positions in protein molecules. In this method one environmentally sensitive group is introduced into a specific position in the protein so that small changes induced by substrates or modifiers can be followed. In this study the synthesis of a potential reporter group reagent, 2-bromoacetamido-4-nitrophenol, was accomplished. This reagent has a moiety which is sensitive to the polarity of the environment and to pH, and which reports changes in its environment to an appropriate detector. It contains a second moiety which reacts …

Studies On The Granule-Moving System Of Melanocytes Of Fundulus Heteroclitus, Lorna Green

Student Theses and Dissertations

Pigment granules in melanocytes of Fundulus heteroclitus exhibit both local movements and long distance intracellular migrations in response to hormones. These movements have been studied and a theory of the granule moving system has been proposed: The granules are in a structured continuum which expands and contracts to move them; the state of the continuum is the resultant of a dynamic equilibrium between expansile and contractile forces manifested in the local movements of granules. The fine structure of the cell has been explored by electron microscopy; the prominent features of the cell are microtubules. Several alternatives for the specific granule …

Studies On The Production Of Γm And Γg Antibodies In The Mouse, Richard Charles Blinkoff

Student Theses and Dissertations

The organ localization of intravenously administered C¹⁴-labeled intact S. adelaide was studied in mice. In the absence of circulating antibody, the spleen had a higher specific activity than other organs studied. The primary antibody response to this antigen was then studied using a specific flagellar immobilization assay. Spleen homogenate supernatants exhibited two distinct antibody peaks which were well separated in time. The serum titer curve was not detectably bimodal. Sera and spleen homogenate supernatants were characterized by electrophoresis, ultracentrifugation, and treatment with 2-mercaptoethanol. The primary antibody response was found to consist of the early, transient production of γM …

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson

Journal of the Department of Agriculture, Western Australia, Series 4

TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.

Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.

The Black Beetle, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

Since first reported in Western Australia 27 years ago, the black beetle has spread widely to become a well-known pest in metropolitan home lawns and public grassed areas.

THE black beetle (Heteronychus sanctae-helenae Blanchard) is a native of South Africa which seems to have first gained a footing in Australia in about 1930, for it was then recorded as a pest of maize in New South Wales. (Gurney 1934).
