Legumes form symbiotic associations with either nitrogen-fixing bacteria or arbuscular mycorrhizal fungi. Formation of these two symbioses is regulated by a common set of signalling components that act downstream of recognition of rhizobia or mycorrhizae by host plants. Central to these pathways is the calcium and calmodulin-dependent protein kinase(More)
Despite significant progress in clarifying the subunit compositions and functions of the multiple NADPH dehydrogenase (NDH-1) complexes in cyanobacteria, the subunit maturation and assembly of their NDH-1 complexes are poorly understood. By transformation of wild-type cells with a transposon-tagged library, we isolated three mutants of Synechocystis sp. PCC(More)
Conserved pathogen-associated molecular patterns (PAMPs), such as chitin, are perceived by pattern recognition receptors (PRRs) located at the host cell surface and trigger rapid activation of mitogen-activated protein kinase (MAPK) cascades, which are required for plant resistance to pathogens. However, the direct links from PAMP perception to MAPK(More)
