Resistance Reaction

Two resistance phenotypes to P. brassicae have been found in A. thaliana. A first resistance phenotype has been detected to the isolate 'e<sub>2</sub>' and is polygenically inherited. The second resistance to isolate 'e<sub>3</sub>' is caused by the dominant resistance gene RPB1. By crossing no influence could be shown for salicylic acid, jasmonic acid and ethylene in the latter resistance reaction. The RPB1 locus was narrowed down to 71 kb on chromosome 1, where three pseudogenes and 13 coding sequences are located. Six of them showed cosegregation with RPB1. None of these sequences have similarities to identified resistance genes or other known genes. Ten coding sequences were expressed, but CDS9 was exclusively expressed in the resistant ecotype Tsu-0.

Abstract Background: DNA methylation plays an important role in the growth and development of plants in response to various abiotic stresses. Salicylic acid (SA) is an important signaling molecule that is synthesized by plants and induces the expression of defense genes. Results: In this paper, we investigated the molecular mechanisms by which an upstream regulator (ACD6) in the SA pathway, an ABA pathway-related gene (ACO3), and a stress resistance gene (GSTF14) were induced by various abiotic stresses. The results demonstrated that abiotic stresses, including drought, cold, and salt stresses, induced the demethylation of the repeats in the promoters of ACD6, ACO3, and GSTF14 and transcriptionally activated their expression. Furthermore, our results revealed that ROS1-mediated DNA demethylation plays an important role in the process of transcriptional activation of ACD6 and GSTF14 when Arabidopsis plants were under cold stress.Conclusions: Our results confirmed that ROS1 plays an important role in the process of defense genes in the SA pathway and stress resistance gene GSTF14 in response to abiotic stresses.

RPP13-Nd-mediated resistance prevents parasitism by five isolates of Peronospora parasitica (At) in a transgenic Arabidopsis. Columbia background. We tested the effect of a number of known disease resistance mutations on the RPP13-Nd function and found that resistance remained unaltered in plants carrying mutations in either EDS1 or NDR1 and in double ndr1-1/eds1-2 mutant lines. Furthermore, we found that pbs2, pad4-1, npr1-1, and rps5-1, which compromise resistance to a number of P. parasitica (At) isolates, had no affect on RPP13-Nd function. In addition, RPP13-Nd-mediated resistance remained unchanged in a background of salicylic acid depletion (nahG). We conclude that RPP13-Nd is the first Arabidopsis R gene product reported to act via a novel signaling pathway that is independent of salicylic acid-mediated responses and is completely independent of NDR1 and EDS1.

AbstractPipecolic acid is essential for the establishment of systemic acquired resistance in plants. It is synthesized in the plastid and further processed in the cytosol to its active form N-hydroxy pipecolic acid. Here we provide strong evidence that the exporter Enhanced Disease Susceptibility 5 is required for the biosynthesis of not only salicylic acid, but also N-hydroxy pipecolic acid, suggesting that it represents a convergent point of plant immunity.
