Characterization 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 کاملComparison of the complete genome sequences of Pseudomonas syringae pv. syringae B728a and pv. tomato DC3000.
The complete genomic sequence of Pseudomonas syringae pv. syringae B728a (Pss B728a) has been determined and is compared with that of P. syringae pv. tomato DC3000 (Pst DC3000). The two pathovars of this economically important species of plant pathogenic bacteria differ in host range and other interactions with plants, with Pss having a more pronounced epiphytic stage of growth and higher abiot...
متن کاملPseudomonas syringae pv. tabaci in papaya seedlings
The natural occurrence of Pseudomonas syringae pv. tabaci causing leaf spot symptoms in papaya seedlings is reported. The pathogen was identified through biochemical, physiological, serological, and molecular assays and artificial inoculations in papaya plants. It was also shown that the strains were pathogenic to bean and tobacco plants. The restriction patterns obtained with Afa I, Alu I, Dde...
متن کاملبیماری لکه‌زاویه‌ای ختمی خواب‌آلود ناشی از یک پاتووار مشابه با Pseudomonas syringae pv. syringae *
بیماری لکه‌زاویه‌ای ختمی خواب‌آلود (Malvaviscus pendulifloru)در چند سال متوالی در برخی از مناطق استان‌های مازندران و گلستان مشاهده شده است. لکه‌ها به قطر 3 تا 4 میلی‌متر، نکروزه، قهوه‌ای رنگ، زاویه‌ای شکل و بدون هاله بودند. از برگ‌های بیمار، یک سودوموناس اکسیداز منفی و تولید کننده لوان جداسازی گردید. جدایه‌ها در ویژگی‌های فنوتیپی ، نوع و میزان اسیدهای چرب سلولی و توالی ناحیه ITS شبیه ب...
