estimation of epiphytic population size of pseudomonas syringae pv. syringae on the weeds of apricot orchards infected to bacterial canker
چکیده مرحله اپی فیتی باکتری pseudomonas syringae pv. syringae (pss) در شیوع و انتشار آن نقش اساسی دارد. این تحقیق با هدف تعیین جمعیت اپی فیتی باکتری pss روی تعدادی از علف های هرز باغات زردآلوی آلوده به بیماری شانکر باکتریایی در منطقه مرند انجام گرفت. در ماه های مهر و آبان از علف های هرز موجود نظیر پنیرک، تاج خروس، گل قاصد، پیچک، سلمه، قیاق و مرغ نمونه برداری شد. رقت های مختلف تا 7-10 از سوسپانس...
متن کاملNew insights on the bacterial canker of kiwifruit (Pseudomonas syringae pv. actinidiae)
Since 2008, Pseudomonas syringae pv. actinidiae, the causal agent of bacterial canker of kiwifruit has become the main pathogen of yellow and green fleshed kiwifruit. All major kiwifruit producing countries in the world have been affected by this bacterial pathogen, leading to substantial economic losses. This review presents the current knowledge on various aspects about the origin, epidemiolo...
متن کاملCharacterization of alginate lyase from Pseudomonas syringae pv. syringae.
The gene encoding alginate lyase (algL) in Pseudomonas syringae pv. syringae was cloned, sequenced, and overexpressed in Escherichia coli. Alginate lyase activity was optimal when the pH was 7.0 and when assays were conducted at 42 degrees C in the presence of 0.2 M NaCl. In substrate specificity studies, AlgL from P. syringae showed a preference for deacetylated polymannuronic acid. Sequence a...
متن کاملRegulation of alginate biosynthesis in Pseudomonas syringae pv. syringae.
Both Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate. However, the environmental signals that trigger alginate gene expression in P. syringae are different from those in P. aeruginosa with copper being a major signal in P. syringae. In P. aeruginosa, the alternate sigma factor encoded by algT (sigma22) and the response regulator AlgR1 are required...
متن کاملPseudomonas syringae pv. actinidiae (PSA) Isolates from Recent Bacterial Canker of Kiwifruit Outbreaks Belong to the Same Genetic Lineage
Intercontinental spread of emerging plant diseases is one of the most serious threats to world agriculture. One emerging disease is bacterial canker of kiwi fruit (Actinidia deliciosa and A. chinensis) caused by Pseudomonas syringae pv. actinidiae (PSA). The disease first occurred in China and Japan in the 1980s and in Korea and Italy in the 1990s. A more severe form of the disease broke out in...
