Other claims from this paper (9)
- Observation Metabolomic profiling of developing maize kernels detected 409 differentially accumulated metabolites.
- Intervention effect Drought stress induced an accumulation of simple sugars and polyunsaturated fatty acids in B73 relative to irrigated plants.
- Intervention effect Drought stress led to accumulation of sphingolipid and sterol metabolites in Lo964.
- Intervention effect Drought stress led to accumulation of phenylpropanoid and dipeptide metabolites in Lo964.
- Intervention effect Drought stress resulted in greater accumulation of reactive oxygen species and aflatoxin in B73 kernels than in Lo964.
- Association Greater reactive oxygen species and aflatoxin accumulation under drought implies a correlation in their production.
- Mechanism Field drought disordered normal metabolic programming in developing maize kernels and caused oxidative stress.
- Observation Glutathione and urea cycles were central among the drought stress responses of developing maize kernels.
- Recommendation The authors suggest that the drought-response findings provide novel targets to enhance drought tolerance and disease resistance in maize.
