Agrobacterium Tumefaciens-Mediated Transformation Of Sesame (Sesamum Indicuml.), Kemal Meli̇h Taşkin, A. Gülhan Ercan, Kenan Turgut

Turkish Journal of Botany

Sesamum indicum L. cv. Özberk was infected with various Agrobacterium tumefaciens strains to screen susceptibility to infection by Agrobacteria. Following infection, tumorigenesis was efficient with wild type A. tumefaciens strains, A281 and A136 NC, and transgenic cells were obtained with disarmed A. tumefaciens strain LBA4404/pBI121, harbouring a reporter gene. At the wound sites, tumorigenesis induced by the succinamopine strain A281 was more extensive than by the octopine strain A136 NC.

Expression And Inheritance Of Gus Gene In Transgenic Tobacco Plants, Ti̇jen Talas Oğraş, Nermi̇n Gözükirmizi

Turkish Journal of Botany

Agrobacterium tumefaciens-mediated transformation of tobacco leaf discs was performed with plant transformation vec-tors of pBI 121 and pGus-Int. Both carry the neomycin phosphotransferase II ( npt II) gene and, unlike the pBI 121, pGus-Int car-ries a portable plant intron inside the beta-glucuronidase (GUS) gene. In addition to the integration of the marker genes into the genomes of primary transformants, R1 and R2 progenies were confirmed by polymerase chain reaction (PCR) and Southern blot analyses. Histochemical and fluorometric analyses were also performed to determine the activity of the GUS gene. Segregation of progenies on kanamycin-resistance trait was also shown as evidence …

Department of Agronomy and Horticulture: Faculty Publications

High Plains disease has the potential to cause significant yield loss in susceptible corn (Zea mays L.) and wheat (Triticum aestivum L.) genotypes, especially in the central and western USA. The primary causal agent, High Plains virus (HPV), is vectored by wheat curl mite (WCM; Aceria tossicheila Keifer), which is also the vector of wheat streak mosaic virus (WSMV). In general, the two diseases occur together as a mixed infection in the field. The objective of this research was to characterize the inheritance of HPV and WSMV resistance using B73 (resistant to HPV and WSMV) × Mo17 (moderately …

Effects Of Sludge Application On Prairie Establishment, Brenda Joan Durbahn

Dissertations and Theses @ UNI

Native prairie in Iowa has all but disappeared since the development of agricultural land by European settlers over the past 165 years. Reconstructing prairie is one way to replace some of the acreage that was lost. A byproduct of settling an area is the generation of garbage and other wastes. Currently there is a surplus of sludge, the waste product of waste water treatment facilities. This material is usually disposed of in landfills, used on agricultural land or reclamation projects.

A small area of prairie was reconstructed on the top of a closed portion of the Black Hawk County Solid …

Measurement Of Sorghum Stalk Strength Using The Missouri-Modified Electronic Rind Penetrometer, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Resistance to lodging is critical in sorghum [Sorghum bicolor (L.) Moench] grown for grain, yet adequate tools for plant breeders to assess this character at or before anthesis have not been developed. The objective of this study was to evaluate whether an electronic penetrometer previously shown to be an effective tool for measuring stalk strength in maize (Zea mays L.) could be usedd to differentiate among grain sorghum hybrids. Entries in three commercial grain sorghum hybrid trials were evaluated for rind penetrometer resistance (RPR) of the peduncle, the lower stalk anthesis and the lower stalk at maturity. Actual …

Plant Hybrid Zones And Insect Host Range Expansion, Diana Pilson

Diana Pilson Publications

The hybrid bridge hypothesis suggests that plant hybrids ‘‘bridge’’ the genetic gap between actual and potential host species, and that, for this reason, herbivorous insects are more likely to evolve an expanded host range in the presence of hybrids. While intuitively appealing, the hypothesis has two implicit assumptions: that phenotypic gaps between potential hosts limit host range, and that characters controlling host use are additively inherited in plant hybrids. Evaluation of these assumptions suggests that operation of the hybrid bridge hypothesis is relatively uncommon. In addition, the hypothesis has not been well integrated into existing theoretical and empirical work on …

Soluble Sugar Composition Of Elaeagnus Angustifolial.Var. Orientalis (L.) Kuntze (Russian Olive) Fruits, F. Ahmet Ayaz, Asim Kadioğlu, Ali̇ True

Turkish Journal of Botany

Soluble sugar composition from ethanolic extract of Elaeagnus angustifoliaL. (Russian olive) ( Elaeagnaceae) collected from six different populations in the Gümüshane-Bayburt Valley was determined by gas chromatography. In the fruits, fructose and glu-cose were determined to be the major sugars. The analysis showed the occurrence of fructose and glucose in concentrations (w/w) of 32.62-34.60% and 23.37-24.10% (minimum-maximum), respectively. Sucrose was not detected in mature fruits while fruc-tose and glucose were identified as the major sugars among these populations.

The Use Of Rapd To Detect Genetic Variation In Populations Of Liatris Aspera Michx., Duane Joseph Kitchen

Dissertations and Theses @ UNI

The tall grass prairie is one of the most degraded and fragmented ecosystems on earth. Interest in conserving, restoring, and reconstructing tallgrass prairie began early in the 1900s, and has increased dramatically since the 1960s. Early restoration and reconstruction efforts relied primarily on seed collected from prairie remnants near the planting site, but with the increase in prairie planting efforts came a greater demand for large quantities of affordable, viable seed of native prairie species. Following an increase in the use of cultivated varieties (cultivars) of seed, concerns over the loss of genetic integrity of local populations and low genetic …
