Plant intracellular innate immune receptor Resistance to Pseudomonas syringae pv. maculicola 1 (RPM1) is activated at, and functions on, the plasma membrane.
Plants deploy intracellular innate immune receptors to recognize pathogens and initiate disease resistance. These nucleotide-binding, leucine-rich repeat (NB-LRR) proteins are activated by pathogen effector proteins that are delivered into the host cell to suppress host defense responses. Little is known about the sites and mechanisms of NB-LRR activation, but some NB-LRR proteins can function ...
متن کاملQuantitative 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 کاملProtein phosphatase AP2C1 negatively regulates basal resistance and defense responses to Pseudomonas syringae
Mitogen-activated protein kinases (MAPKs) mediate plant immune responses to pathogenic bacteria. However, less is known about the cell autonomous negative regulatory mechanism controlling basal plant immunity. We report the biological role of Arabidopsis thaliana MAPK phosphatase AP2C1 as a negative regulator of plant basal resistance and defense responses to Pseudomonas syringae. AP2C2, a clos...
