Quantitative trait loci for partial resistance to Pseudomonas syringae pv. maculicola in Arabidopsis thaliana
Segregation of partial resistance to Pseudomonas syringae pv. maculicola (Psm) ES4326 was studied in the recombinant inbred population created from accessions (ecotypes) Columbia (Col-4), the more susceptible parent, and Landsberg (Ler-0). Plants were spray inoculated with lux-transformed bacteria in experiments to measure susceptibility. The amount of disease produced on a range of Col × Ler l...
متن کاملVirulence of the phytopathogen Pseudomonas syringae pv. maculicola is rpoN dependent.
We cloned the rpoN (ntrA and glnF) gene encoding sigma(54) from the phytopathogen Pseudomonas syringae pv. maculicola strain ES4326. The P. syringae ES4326 rpoN gene complemented Pseudomonas aeruginosa, Escherichia coli, and Klebsiella aerogenes rpoN mutants for a variety of rpoN mutant phenotypes, including the inability to utilize nitrate as sole nitrogen source. DNA sequence analysis of the ...
متن کاملبیماری لکه برگی باکتریایی خاکشیر تلخ ناشی از یک پاتووار مشابه با Pseudomonas syringae pv. maculicola *
در بهار سال 1382 یک بیماری لکه برگی روی بوته‌های خاکشیر وحشی یا تلخ (Sisymbrium irio) در منطقه پلوراستان تهران دیده شد. لکه‌ها مدور تا نامنظم، قهوه‌ای تا سیاه رنگ، نکروزه، به قطر نیم تا یک و نیم میلی‌متر و اغلب دارای هاله سبز کمرنگ تا زرد بودند. با کشت نمونه‌های آلوده روی محیط آگار غذایی حاوی ساکارز، یک سودوموناس لوان مثبت جدا ...
متن کاملA High-Throughput Forward Genetic Screen Identifies Genes Required for Virulence of Pseudomonas syringae pv. maculicola ES4326 on Arabidopsis
Successful pathogenesis requires a number of coordinated processes whose genetic bases remain to be fully characterized. We utilized a high-throughput, liquid media-based assay to screen transposon disruptants of the phytopathogen Pseudomonas syringae pv. maculicola ES4326 to identify genes required for virulence on Arabidopsis. Many genes identified through this screen were involved in process...
متن کاملCoronatine Facilitates Pseudomonas syringae Infection of Arabidopsis Leaves at Night
In many land plants, the stomatal pore opens during the day and closes during the night. Thus, periods of darkness could be effective in decreasing pathogen penetration into leaves through stomata, the primary sites for infection by many pathogens. Pseudomonas syringae pv. tomato (Pst) DC3000 produces coronatine (COR) and opens stomata, raising an intriguing question as to whether this is a vir...
