Wheat and triticale plants were transformed by bombardment of isolated scutella with a genetic construct consisting of the two anthocyanin biosynthesis regulatory genes, C1 and Bperu, each under the control of the Ltp1 embryo-specific promoter. Transgenic plants were obtained in the absence of selective pressure and selectable marker gene at a(More)
The excessive use of antibiotics in food animal production has contributed to resistance in pathogenic bacteria, thereby triggering regulations and consumer demands to limit their use. Alternatives for disease control are therefore required that are cost-effective and compatible with intensive production. While vaccines are widely used and effective, they(More)
Three barley tissue-specific promoters (Dhn12, Itr1, and Ltp1) were transcriptionally fused to the C1 and/or the B-peru genes involved in anthocyanin biosynthesis. Transient expression of these constructs was examined in different wheat tissues. Constructs with tissue-specific promoters were only active in embryos. A green fluorescent protein (GFP) driven(More)
A robust, reproducible method of Agrobacterium-mediated transformation was developed for Lupinus mutabilis Sweet (tarwi), a large-seeded Andean legume. Initially, a regeneration and transformation protocol was developed using a plasmid which contained a bifunctional fusion gene conferring both β-glucuronidase (gus) and neomycin phosphotransferase(More)
The production of recombinant vaccines in plants may help to reduce the burden of veterinary diseases, which cause major economic losses and in some cases can affect human health. While there is abundant research in this area, a knowledge gap exists between the ability to create and evaluate plant-based products in the laboratory, and the ability to take(More)
The plant seed is a leading platform amongst plant-based storage systems for the production of recombinant proteins. In this study, we compared the activity of human adenosine deaminase (hADA) expressed in transgenic seeds of three different plant species: pea (Pisum sativum L.), Nicotiana benthamiana L. and tarwi (Lupinus mutabilis Sweet). All three(More)
