You-Liang Peng; Jiko Shishiyama Canadian Journal of Botany 1988. doi:10.1139/b88-107
Other claims from this paper (10)
- Observation Conidia of Pyricularia oryzae germinated and formed appressoria at a similar frequency in all four rice cultivars.
- Observation Fungal penetration frequency differed among rice cultivars, not clearly related to race-specific resistance.
- Association Growth inhibition of infection hyphae was more pronounced in incompatible race-cultivar combinations than in compatible ones.
- Observation Inhibition of infection hyphae was correlated with expression of race-specific resistance in rice.
- Observation The rice cultivars showed five types of cellular reactions to the pathogen.
- Observation Type B reactions (light browning and aniline blue staining of epidermal cell walls) were the first cellular reactions seen in all cultivars.
- Observation The frequency of type B reactions decreased after their first appearance.
- Observation Other cellular reactions, such as cytoplasmic granulation or cell necrosis, increased after type B reactions declined.
- Mechanism Cytoplasmic granulation or cell necrosis may be generated from type B reactions.
- Observation Inhibition of infection hyphae coincided in time with the occurrence of type B reactions.
