    Analysis of host specialization on tobacco of the pathogenic fungus Phytophthora parasitica; study of the involvement of a proteic elicitor

    TRENTIN F.
    Institut Expérimental du Tabac, Bergerac, France
    The behavior of Phytophthora parasitica was studied with the help of an original test for the inoculation of the plantlet roots which showed the existence of three types of isolates: 1) non parasitic isolates of tobacco which secrete parasiticein (N-E+), ...
