- Intervention effect Drought significantly reduced kernel development.
- Intervention effect Drought significantly reduced starch accumulation.
- Intervention effect Drought significantly reduced starch biosynthetic enzyme activities.
- Intervention effect Drought changed starch granule morphology.
- Observation At 10 days after pollination, water stress yielded 487 differentially accumulated proteins.
- Observation At 25 days after pollination, water stress yielded 465 differentially accumulated proteins.
- Intervention effect Drought downregulated oxidation reduction and oxidoreductase proteins.
- Intervention effect Drought downregulated peroxidase, catalase, and glutamine synthetase.
- Intervention effect Drought downregulated abscisic acid stress ripening 1 and lipoxygenase.
- Intervention effect Several endosperm and starch biosynthesis proteins were upregulated early under water stress.
- Mechanism Early protein upregulation may have accelerated endosperm development and starch synthesis.
- Observation Seventeen proteins remained upregulated at both sampling stages.
- Observation Eleven proteins remained downregulated at both sampling stages.
- Observation Four maize homologs were proposed as candidate proteins affecting kernel development and drought response.
- Association Drought induced proteomic changes correlated strongly with kernel development and starch accumulation.
- Association Kernel development and starch accumulation were closely related to waxy maize yield and quality.
