Abstract:
Recent advances in cloning avirulence genes from a rust fungus and three oomycete species have provided the novel insight that these eukaryotic plant pathogens deliver small proteins into the host cell cytoplasm where they are recognized by resistance proteins. Anne Rehmany et al. have recently identified a potential host-targeting signal in oomycete avirulence proteins from Hyaloperonospora parasitica, Phytophthora sojae and Phytophthora infestans that might be involved in transporting proteins into the host cell. This signal is surprisingly similar to the host targeting signal used by the malaria pathogen Plasmodium fulciparum to target virulence proteins to the mammalian host cell.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
