Other claims from this paper (9)
- Intervention effect Cotton buds exposed to adult cotton fleahoppers produced ethylene at theoretical abscission-inducing rates by 24 h.
- Intervention effect Cotton buds exposed to nymphal cotton fleahoppers produced ethylene at theoretical abscission-inducing rates by 24 h.
- Intervention effect Inoculation with three fleahopper-associated microorganisms promoted cotton shoot-tip ethylene production to theoretical abscission-inducing rates by 24 h.
- Intervention effect Fleahoppers caused cotton shoot tips to darken and soften, changes absent from controls.
- Intervention effect Injected microorganisms caused cotton shoot tips to darken and soften, changes absent from controls.
- Observation In culture, Xanthomonas campestris pv malvacearum produced little ethylene.
- Observation In culture, Penicillium purpurogenum produced higher ethylene levels.
- Observation In culture, P. glabrum produced higher ethylene levels.
- Mechanism The authors propose cotton fleahopper salivary fluids containing cell-wall hydrolyzing enzymes as the primary ethylene-induction mechanism.
