Plant Molecular Biology

Innate Immunity

How do plants defend themselves against pathogens? A focus of this research is MAP kinase 4 (MPK4) which regulates two major pathways leading to disease resistance (Petersen et al. 2000 Cell 103, 1111 ). Our studies show that MPK4 functions downstream of innate immunity receptors via a nuclear substrate MKS1 (Andreasson et al. 2005 EMBO J. 24, 2579 ) to regulate the activity of the WRKY33 transcription factor which in turn controls the production of anti-microbial phytoalexins (Qiu et al. 2008 EMBO J. 27, 2214 ).

Programmed Cell Death

How do plant cells die? A focus here is the Accelerated Cell Death 11 mutant (acd11; Brodersen et al. 2002 Genes Dev. 16, 490) that constitutively expresses innate immunity genes accompanying the hypersensitive cell death response normally triggered by pathogens perceived by innate immun receptors. Our reverse and forward genetic studies identify pathways and genes required for cell death (Brodersen et al. 2005 Plant Physiol. 138, 1037; Olszak et al. 2005 Plant Sci. 170, 614).
