The novel ZmTCP7 transcription factor targets AGPase-encoding gene to regulate storage starch accumulation in maize.

The process of starch biosynthesis is a major developmental event that affects the final grain yield and quality in maize ( L.), and transcriptional regulation plays a key role in modulating the expression of the main players in the pathway. , which encodes the small subunits of AGPase, is a rate-controlling gene of the pathway; however, much remains unknown about its transcriptional regulation.
