Barley compatibility factors pivotal for root colonisation and manipulation of basal defence by Piriformospora indica (Project)
Global transcription profiling revealed a significant suppression of the plant innate immune system by Piriformospora indica. Subsequent analyses identified gibberellic acid (GA) as compatibility factor; an activity that might be partly explained by a GA-mediated modification of plant immune signalling (Schäfer et al., 2009). In addition, lipid metabolism was found to be altered in P....

Establishment of cell-specifically inducible expression systems in transgenic barley and maize (Project)
Experimental approaches to over-expression or knock-down of genes implicated in plant pathosystems using constitutive or tissue-specific promoters often result in pleiotrophic effects such as developmental aberrations or reduced viability. Hence, the immediate gene function confined to the context of plant-pathogen interaction cannot be studied properly using these conventional expression systems...

Redirection of photoassimilate partitioning by biotrophic, hemibiotrophic and mutualistic fungi through altered transporter gene expression (Project)
Allocation and distribution of carbohydrates, amino acids, ions, water and numerous other compounds is tightly regulated in higher plants. It is essential for sufficient and timely supply of these compounds to multiple sinks that continuously change in strength and number during development and in response to environmental factors. During plant-pathogen interactions the formation of new sink...

Metabolic determinants in the interaction of biotrophic and hemibiotrophic fungi with cereals (Project)
Major objective of project B6 is to unravel determinants in maize metabolism for the compatibility with the biotrophic fungus Ustilago maydis and the hemibiotrophic fungus Colletotrichum graminicola. Our aim is to uncover the function of genes that are essentially participating in the redirection of host metabolism in response to infection by respective pathogens. In both pathosystems, we employ...

Towards dissecting mechanisms of compatibility in plants and fungi: a systemsbiology approach combining transcriptome and metabolome data (Project)
In FOR 666 Phase I, transcripts and metabolites were identified that confer compatibility in different plant-microbe systems. In FOR 666 Phase II, efforts for the detection of further system-specific and universal compatibility factors will base on comprehensive analyses of the existing transcriptome and metabolome data in combination with new data generated in individual projects. In a...

Interactive signal transfer in the leaf apoplast between host and pathogen during successful infection (Project)
The aim of this project is to unravel electrophysiological changes in compatible interactions of barley with pathogenic and mutualistic fungi. In leaves of different barley genotypes, which are susceptible to infection by biotrophic (e.g. Blumeria graminis) or hemibiotrophic fungi (e.g. Bipolaris sorokiniana), as well as in leaves of super-susceptible transgenic barley (expressing the...

The role of RBOH-type NADPH oxidases in compatibility of barley with fungal organisms (Project)
Reactive oxygen species (ROS) play a central role in interaction of plants with microbial pathogens. Membrane-resident NADPH oxidases (Respiratory burst oxidase homologues, RBOHs) are prominent sources of ROS in plant-microbe interactions. RBOHs are also involved in plant development, wound responses and adaptation to the abiotic environment. Our preliminary work points to a role of barley RBOHs...
