Phosphatidylcholine Synthesis in Castor Bean Endosperm : I. Metabolism of l-Serine.

abstract：:In culture, the phytopathogenic fungus Phytophthora cryptogea secretes a protein which elicits hypersensitive-like necroses and protects tobacco plants against invasion by the pathogen Phytophthora parasitica var. nicotianae. This protein, named cryptogein, has been purified and its amino acid sequence determined. In ...
