Cytological Aspects of Infection by the Rice Blast Fungus Pyricularia Oryzae

  • Hironori Koga


Rice blast, caused by Pyricularia oryzae Cay. (telemorph: Magnaporthe grisea (Hebert) Barr) (Barr 1977) is a major factor limiting yields of rice (Otyza sativa L.) world wide. An understanding of the mechanisms underlying pathogenesis and host specificity is critical to future progress in both applied and basic aspects of rice blast pathology. Many studies on the penetration process of P. oryzae have been made on artificial substrate (Bourett and Howard, 1990; Howard and Ferrari, 1989; Howard et al., 1991), on Bryophyllum pinnatum (Woloshuk et al., 1983), on goosegrass and weeping lovegrass (Heath et al., 1990,1992) and on rice (Hashioka et al., 1968; Koga, 1994 a,b; Koga, 1995; Yoshii, 1937).
