各種いもち病菌に対するイネの宿主,非宿主反応の顕微鏡観察

In many studies on the process of race-specific resistance and the resistance of non-host plants to plant pathogenic fungi, studies with light microscope has revealed the timing of the cessation of fungal growih during resistant reactions and the relationship between fungal development and host cell death. To investigate the specific processes involved in these types of resistance may provide not only information about the way in which hostparasite specificity is determined but also some promise for more precise and longlasting control of plant pathogens in the future. Unfortunately, however, similar evidence is remarkably scarce for several Pyricularia spp. infection. Therefore, the object of the present study is to search for significant and key responses of the rice plants against pathogens or non-pathogens in their early infection.
