Other claims from this paper (8)
- Observation Dhurrin content in sorghum varies with plant age and growth conditions.
- Observation The cyanide potential of sorghum is highest shortly after the onset of germination.
- Intervention effect Nitrogen application induces an increase in dhurrin content in older sorghum plants.
- Association Dhurrin content in sorghum correlates well with the activity, protein and mRNA levels of CYP79A1 and CYP71E1 at all stages.
- Observation The activity of CYP79A1 is lower than the activity of CYP71E1 during sorghum development.
- Mechanism CYP79A1 probably catalyzes the rate-limiting step in dhurrin synthesis in sorghum.
- Observation The site of dhurrin synthesis in sorghum shifts from leaves to stem during plant development.
- Mechanism Dhurrin content in sorghum is largely determined by transcriptional regulation of CYP79A1 and CYP71E1.
