The hrpZ Gene of Pseudomonas syringae pv. phaseolicola Enhances Resistance to Rhizomania Disease in Transgenic Nicotiana benthamiana and Sugar Beet
To explore possible sources of transgenic resistance to the rhizomania-causing Beet necrotic yellow vein virus (BNYVV), Nicotiana benthamiana plants were constructed to express the harpin of Pseudomonas syringae pv. phaseolicola (HrpZ(Psph)). The HrpZ protein was expressed as an N-terminal fusion to the PR1 signal peptide (SP/HrpZ) to direct harpin accumulation to the plant apoplast. Transgene ...
متن کاملMolecular breeding for resistance to rhizomania in sugar beets
Lennefors, B-L. 2006. Molecular breeding for resistance to rhizomania in sugar beets. Doctor’s dissertation ISSN: 1652-6880, ISBN: 91-576-7255-5 Rhizomania is one of the most destructive sugar beet diseases. It is caused by Beet necrotic yellow vein virus (BNYVV) vectored by the soilborne protoctist Polymyxa betae Keskin. The studies in this thesis evaluated natural and transgenic resistances t...
متن کاملProteomic Profiling of Sugar Beet (Beta vulgaris) Leaves during Rhizomania Compatible Interactions
Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV), severely impacts sugar beet (Beta vulgaris) production throughout the world, and is widely prevalent in most production regions. Initial efforts to characterize proteome changes focused primarily on identifying putative host factors that elicit resistant interactions with BNYVV, but as resistance breaking strains become more prevale...
متن کاملMolecular Biology of the Beet necrotic yellow vein virus
Beet necrotic yellow vein virus is the etiological agent of one of the most devastating sugar beet viral diseases: rhizomania. This review describes the molecular biology of the rhizomania disease, the functions of the BNYVV encoded proteins, the consequences of their expression as well as the biology of the BNYVV vector, Polymyxa betae. Root proliferation is an important part of the well-known...
متن کاملHigh Level Resistance against Rhizomania Disease by Simultaneously Integrating Two Distinct Defense Mechanisms
With the aim of achieving durable resistance against rhizomania disease of sugar beet, the employment of different sources of resistance to Beet necrotic yellow vein virus was pursued. To this purpose, Nicotiana benthamiana transgenic plants that simultaneously produce dsRNA originating from a conserved region of the BNYVV replicase gene and the HrpZ(Psph) protein in a secreted form (SP/HrpZ(Ps...
