Other claims from this paper (12)
- Observation Searches found several inhibitors of fungal development in wheat.
- Observation Searches found little evidence of postinfection increases in these inhibitors.
- Observation No evidence was obtained for phytoalexin formation in wheat.
- Association Hypersensitivity was closely associated with most studied forms of wheat resistance.
- Mechanism Histology suggested rust-strain and Lr20-specific elicitors cause hypersensitivity.
- Observation Heat and epidermis-free leaf experiments were consistent with the specific-elicitor interpretation.
- Observation Attempts to extract specific elicitors from infected wheat leaves failed.
- Observation Extracts of infected leaves yielded nonspecific elicitors.
- Observation Nonspecific elicitors were obtained from washing fluids of leaves infected by leaf and stem rust.
- Observation Nonspecific elicitors were also obtained from germ tubes of both rust species.
- Association Nonspecific elicitors selected for a chromosome 5 A determined character in some wheat cultivars.
- Mechanism The authors suggest nonspecific elicitors act as incompatibility factors between rust fungi and wheat.
