Random amplified polymorphic DNA analysis of China isolates of Phytophthora parasitica var. nicotianae from different districts
China isolates of Phytophthora parasitica var. Nicotianae have been divided into three large pathogenic groups (PGS) (Hv(A), Iv(B), Wv(C)) which came from Yunnan, Shandong and Liaoning. These three districts belong to main tobacco regions in China: 15 isolates derived from Yunnan of the southwest, 13 isolates from Shandong of the east and 20 isolates from Liaoning of the northeast. PGS were det...
متن کاملLipoxygenase gene expression in the tobacco-Phytophthora parasitica nicotianae interaction.
A recently isolated cDNA clone of tobacco (Nicotiana tabacum L.) lipoxygenase (LOX) was used to study LOX gene expression in tobacco cell-suspension cultures and intact plants in response to infection with Phytophthora parasitica nicotianae (Ppn). Southern blot analysis of tobacco DNA indicated that only a small number of LOX genes hybridize to this probe. These genes were not constitutively ex...
متن کاملInitial Cellular Interactions Between Thielaviopsis basicola and Tobacco Root Hairs.
ABSTRACT Cellular events that occur during the initial interactions between Thielaviopsis basicola and root hairs of tobacco (Nicotiana tabacum) were examined microscopically. Time-course documentation of the infection process indicated a dynamic interaction between T. basicola and the living host cell. Upon root hair contact and recognition, the vegetative apex of T. basicola rapidly different...
متن کاملUse of a new tetrazolium-based assay to study the production of superoxide radicals by tobacco cell cultures challenged with avirulent zoospores of phytophthora parasitica var nicotianae
The relationship between the production of reactive oxygen species and the hypersensitive response (HR) of tobacco (Nicotiana tabacum L. ) toward an incompatible race of the Oomycete Phytophthora parasitica var nicotianae has been investigated. A new assay for superoxide radical (O2-) production based on reduction of the tetrazolium dye sodium,3'-(1-[phenylamino-carbonyl]-3, 4-tetrazolium)-bis(...
متن کاملThe incompatible interaction between Phytophthora parasitica var. nicotianae race 0 and tobacco is suppressed in transgenic plants expressing antisense lipoxygenase sequences.
Nicotiana tabacum 46-8 cultivar displays an incompatible interaction with race 0 of Phytophthora parasitica var. nicotianae (Ppn), a fungal pathogen of most tobacco cultivars. At the plant level, incompatibility is characterized by the induction of lipoxygenase (LOX, EC = 1.13.11.12) activity and localized hypersensitive cell death before defense gene activation. To evaluate the involvement of ...
