e0“By contrast, the control of leaf activity by protein content was less obvious than in the grain, and changes in leaf enzyme specific activity were suggested during the first 20 d after pollination.”

Other claims from this paper (10)
- Association Maize grain enzyme activity and starch accumulation rate coincided for two years from pollination to maturity outdoors.
- Association The adjacent maize leaf showed no corresponding correlation between enzyme activity and starch accumulation.
- Observation Maize leaves showed large year-to-year differences in starch accumulation pattern.
- Mechanism Parallel changes in Bt2 and Sh2 protein content explained maize grain enzyme activity variation.
- Mechanism Bt2 and Sh2 mRNA changes preceded similar peptide changes in maize grain, suggesting transcriptional control.
- Observation Changes in maize leaf enzyme specific activity were suggested in the first 20 days after pollination.
- Observation A maize leaf clone L2 homologous to Bt2 was isolated and represented one-third of the mature peptide.
- Observation Bt2 and L2 had 97% coding-region homology.
- Observation Bt2 and L2 had poor homology at the 3′ noncoding border.
- Mechanism Bt2 and L2 arise from distinct maize genes with tissue-specific expression, explaining leaf–grain peptide and mRNA size differences.
