Transformation of alfalfa using Agrobacterium tumefaciens

Creator:: Gelford, Inga L.
Abstract:: Agrobacterium tumefaciens, the causative agent of crown gall disease, does not readily infect commercial varieties of alfalfa (Medicago sativa). Cloned virulence genes from the megaplasmid pTiBo542 have been shown to enhance Agrobacterium host range and infectivity on dicotyledonous plants. To obtain a gene transfer system for commercial alfalfa cultivars, an...

Advances in expression of heterologous protein products by Streptococcus gordonii

Creator:: Warren, Travis Kent
Abstract:: Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...

Genetics of partial incompatibility and improvement of haploid production in Hordeum vulgare L. x H. bulbosum L. crosses

Creator:: Chen, Fu-chiang and Chen, Fuqiang
Abstract:: The production of barley (Hordeum vulgare L.) haploids by crossing with H. bulbosum is a widely used tool in breeding and genetics. Certain barley genotypes have low seed set in this interspecific cross, a phenomenon known as partial incompatibility. Haploid production efficiency and gamete sampling are important issues with the...

Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

Creator:: Li, Jingyi
Abstract:: Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

Exploration of the feasibility of developing a winter hardy 'Marion' blackberry through genetic engineering

Creator:: Meng, Rengong
Abstract:: Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...

Genetic engineering of disease resistance in poplar : effects of bacterio-opsin over-expression and analysis of a copper-based system for resistance-gene activation

Creator:: Mohamed, Rozi
Abstract:: We tested a synthetic bacterio-opsin (bO) gene derived from Halobacterium halobium for its effect on disease resistance in transgenic poplar hybrids, and assessed a genetic system for controlling expression of this gene. In tobacco the bO gene caused necrotic lesions similar to an induced hypersensitive response (HR), increased levels of...

Factors affecting adventitious shoot formation and expression of microprojectile-introduced DNA in Douglas-fir cotyledons

Creator:: Goldfarb, Barry
Abstract:: Our goal was to develop knowledge that will enable insertion of foreign genes into Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] trees. This required improvement of a tissue culture system for producing adventitious shoots from cotyledons, and study of factors affecting gene delivery, expression, and analysis. Administering a short-duration, concentrated liquid pulse...
