文摘
- •
We examine coordination of sucrose transport and conversion to starch in wheat grains.
- •
Transcriptional regulation of specific genes appear to underlie this coordination.
- •
Responsiveness of the target genes to ABA was examined during grain filling.
- •
ABA represses the transcription of major sucrose transport and cleavage genes.
- •
Transcription of all the predominant starch synthesis genes is also repressed by ABA.
