Murine toxicit of Agrobacterium tumefaciens.
Eleven strains of the crown gall organism, Agrobacterium tumefaciens, tested by intraperitoneal injection into mice, were lethal within 48 hr. Five other species had some lethal strains. The lethal effect of A. tumefaciens appeared to be the result of a toxic rather than an infectious process, since histopathological anomalies were not found in mice injected with live cultures and since heat-ki...
متن کاملThe Oncogenes of Agrobacterium Tumefaciens and Agrobacterium Rhizogenes
The common soil bacteria Agrobacterium tumefaciens and Agrobacterium rhizogenes are unique genetic pathogens capable of fundamentally redirecting plant metabolism in order to generate macroscopic tissue masses (crown galls and hairy roots, respectively) which support the growth of large populations of Agrobacteria. Central to pathogenesis is the horizontal transfer of a suite of oncogenes from ...
متن کاملAgrobacterium tumefaciens-mediated transformation of yeast.
Agrobacterium tumefaciens transfers a piece of its Ti plasmid DNA (transferred DNA or T-DNA) into plant cells during crown gall tumorigenesis. A. tumefaciens can transfer its T-DNA to a wide variety of hosts, including both dicotyledonous and monocotyledonous plants. We show that the host range of A. tumefaciens can be extended to include Saccharomyces cerevisiae. Additionally, we demonstrate t...
متن کاملانتقال ژن رمز کننده mannitol-1-phosphate dehydrogenase به چغندرقند بواسطه agrobacterium tumefaciens
تنش های غیرزیستی، به ویژه شوری و خشکی علل اصلی کاهش محصول در جهان می باشند. این تنش ها شدیداً بر عملکرد چغندرقند و کیفیت آن تأثیر می گذارند. ثابت شده است که مانیتول نقش محوری در تعدیل تنش های اسمزی و شوری در گیاهان دارد. ژن mtld آنزیم مانیتول-1- فسفات دهیدروژناز را رمز می کند که این آنزیم بیوسنتز مانیتول را کاتالیز می نماید. در این تحقیق از دو ژنوتیپ دیپلویید چغندرقند sbs1-4 و sbs1-5 برای تراریخ...
15 صفحه اولTransformation of Arabidopsis thaliana with Agrobacterium tumefaciens.
Transformed Arabidopsis thaliana plants have been produced by a modified leaf disk transformation-regeneration method. Leaf pieces from sterilely grown plants were precultured for 2 days and inoculated with an Agrobacterium tumefaciens strain containing an avirulent Ti (tumor-inducing) plasmid with a chimeric gene encoding hygromycin resistance. After cocultivation for 2 days, the leaf pieces w...
