To identify molecular markers for the resistance gene Mlg located on chromosome 4H, a cDNA-AFLP approach was carried out on near-isogenic lines. Based on the identification of a differentiating fragment of 37 bp, which turned out to be part of a nucleoside diphosphate kinase as estimated by BLASTN, a CAPS marker has been developed, which co-segregated with Mlg in a population of 738 F-2-plants. Due to its co-dominant inheritance, clear banding pattern and close linkage this marker is well suited for marker-based selection procedures.

Here, NO synthesis was analysed in the phloem of Vicia faba in response to stress- and pathogen defence-related compounds. The chemical stimuli were added to shallow paradermal cortical cuts in the main veins of leaves attached to intact plants. NO production in the bare-lying phloem area was visualized by real-time confocal laser scanning microscopy using the NO-specific fluorochrome 4,5-diaminofluorescein diacetate (DAF-2 DA). Abundant NO generation in companion cells was induced by 500 mu M salicylic acid (SA) and 10 mu M hydrogen peroxide (H2O2), but the fungal elicitor chitooctaose was much less effective. Phloem NO production was found to be dependent on Ca2+ and mitochondrial electron transport and pharmacological approaches found evidence for activity of a plant NO synthase but not a nitrate reductase. DAF fluorescence increased most strongly in companion cells and was occasionally observed in phloem parenchyma cells. Significantly, accumulation of NO in sieve elements could be demonstrated. These findings suggest that the phloem perceives and produces stress-related signals and that one mechanism of distal signalling involves the production and transport of NO in the phloem.

The question was raised whether a biotrophically growing fungus manipulates the electrical driving forces (membrane potential., transmembrane pH), required for H+ cotransport of energy-rich compounds. Electrodes were positioned in the substomatal cavity of open stomata or on the leaf surface, and pH was measured continuously up to several days during fungal development. We demonstrate that surface and apoplastic fluids are electrically coupled and respond in a similar manner to stimuli. Apoplastic pH, monitored from the moment of inoculation with conidia, reveals several phases: 2-4 h after inoculation of the barley leaf with either fungus, the host displays rapid transient responses after its first contact with the fungal cell wall; apoplastic pH and pCa increases, cytoplasmic pH and pCa decreases. About 1 day after inoculation, the apoplastic pH increases by up to 2 pH units, which is thought to reflect a resistance response against the intruder. Whereas barley leaf cells possess a membrane potential of -152 +/- 5 mV, hyphae of B. graminis yield -251 +/- 8 mV, indicative of a substantial driving force advantage for the fungus. Although the resting membrane potential of barley remains constant during the first days after inoculation, leaves infected with B. sorokiniona get confronted with an energy problem, indicated by a retarded repolarization following a ��light-off" stimulus.

In either case, establishment of the parasitic or mutualistic interaction is the result of a highly sophisticated cross-talk between the partners. Despite the ecological importance of mutualistic symbioses, the molecular events accompanied by this phenomenon are far from being understood. Piriformospora indica represents a recently discovered fungus that transfers considerable beneficial impact to its host plants. In this review, the current knowledge on this novel symbiosis is summarized by focusing on its biological effects in hosts and the role of programmed cell death in the establishment of the mutualistic interaction.

Infection of the roots with pathogenic necrotrophic fungi of the genus Fusarium, in contrast, leads to necrotized roots and severe reduction of root and shoot biomass. Upon infestation with P. indica, roots were protected from Fusarium infections as evidenced by reduced root rot symptoms. Consistently, Fusarium quantification using quantitative polymerase chain reaction (Q-PCR) revealed a correlation between reduced root rot symptoms and the relative amount of fungal DNA. In vitro analysis of the interaction of P. indica and F. graminearum under axenic culture conditions did not reveal reciprocal growth inhibition suggesting that retardation of Fusarium in roots is mediated by a plant response rather than by antibiosis. Expression of pathogenesis-related genes strongly increased in response to F. graminearum infections, but in contrast was diminished in the presence of P. indica, indicating that PR proteins do not play a crucial role in the P. indica-mediated resistance response to Fusarium.

Endophytic fungal colonization leads to enhanced plant growth while host cell. death is required for proliferation in differentiated root tissue to form a mutualistic interaction. Colonization of barley roots by P. indica and related Sebacina vermifera strains also leads to systemic resistance against the leaf pathogenic fungus Blumerio graminis f.sp. hordei due to a yet unknown mechanism of induced resistance. In order to elucidate plant response pathways governed by these root endophytes, we analyzed gene expression in barley plants exhibiting an established symbiosis with P. indica 3 weeks after inoculation. P. indica-cotonized roots showed no induction of defence-related genes, white other genes showed a differential regulation pattern indicating a faster P. indica-dependent root development. Gene expression analysis of leaves detected only few systemically induced mRNAs. Among differentially regulated transcripts, we characterized the pathogenesis-related gene HvPr17b and the molecular chaperone HvHsp70 in more detail. HvPr17b shows similarity with TaWC15, a wheat gene inducible by chemical resistance inducers and salicylate, and was previously proven to exhibit antifungal activity against B. graminis. HvHsp70 is the first gene found to systemically indicate root colonization with endophytic fungi of the order Sebocinales. Both genes are discussed as markers for endophytic colonization and resulting systemic responses. (C) 2007 Elsevier GmbH. All rights reserved.

Designing such a heterogenous MP-SoC architecture bears enormous potential for optimization, but requires a system-level design environment and methodology to evaluate architectural alternatives. This paper proposes a methodology to jointly design and optimize the processor architecture together with the on-chip communication based on the LISA Processor Design Platform in combination with SystemC Transaction Level Models. The proposed methodology advocates a successive refinement flow of the system-level models of both the processor cores and the communication architecture. This allows design decisions based on the best modeling efficiency, accuracy and simulation performance possible on the respective abstraction level. The effectiveness of our approach is demonstrated by the exemplary design of a dual-processor JPEG decoding system.
