【 摘 要 】

The phytopathogenic fungi Phytophthora cinnamomi cause systemic leaf necrosis on its non-host tobacco; in culture, it secretes a protein, called cinnamomin, which elicits leaf necrosis and protects tobacco against the pathogen Phytophthora nicotianæ, in a way similar to cryptogein and different from capsicein, elicitins of known amino acid sequences. The cinnamomin sequence has been determined and compared to other elicitins. The differences in the 3 elicitin sequences were correlated to the biological acivities: 2 lysines were ascribed as the key amino acids involved in the differential control of protection with respect to necrosis.
