Genetically engineered stem rust resistance in barley using the Rpg1 gene.
The stem-rust-susceptible barley cv. Golden Promise was transformed by Agrobacterium-mediated transformation of immature zygotic embryos with the Rpg1 genomic clone of cv. Morex containing a 520-bp 5' promoter region, 4,919-bp gene region, and 547-bp 3' nontranscribed sequence. Representatives of 42 transgenic barley lines obtained were characterized for their seedling infection response to pat...
متن کاملThe barley stem rust-resistance gene Rpg1 is a novel disease-resistance gene with homology to receptor kinases.
Stem rust caused by Puccinia graminis f. sp. tritici was among the most devastating diseases of barley in the northern Great Plains of the U.S. and Canada before the deployment of the stem rust-resistance gene Rpg1 in 1942. Since then, Rpg1 has provided durable protection against stem rust losses in widely grown barley cultivars (cvs.). Extensive efforts to clone Rpg1 by synteny with rice provi...
متن کاملProteolysis of the barley receptor-like protein kinase RPG1 by a proteasome pathway is correlated with Rpg1-mediated stem rust resistance.
In plants, disease resistance mediated by the gene-for-gene mechanism involves the recognition of specific effector molecules produced by the pathogen either directly or indirectly by the resistance-gene products. This recognition triggers a series of signals, thereby serving as a molecular switch in regulating defense mechanisms by the plants. To understand the mechanism of action of the barle...
متن کاملMolecular Mapping of Leaf Rust Resistance Gene Rph5 in Barley
can be easily identified and transferred into appropriate germplasm (Parlevliet, 1976). To date, 16 major raceLeaf rust caused by Puccinia hordei G. Otth is an important disease specific genes (designated as Rph1 to Rph16) for leaf of barley (Hordeum vulgare L.) in many regions of the world. Yield losses up to 32% have been reported in susceptible cultivars. The rust resistance have been identi...
متن کاملGenetically Engineered Mesenchymal Stem Cells Stably Expressing Green Fluorescent Protein
Objective(s) Mesenchymal stem cells (MSCs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. Human mesenchymal stem cells (hMSCs) are ideal targets in cell transplantation and tissue engineering. Enhanced green fluorescent protein (EGFP) has been an important reporter gene for gene therapy. The aim of this stu...
