摘要： MADS-box family proteins play an important role in grain formation and flower development; however, the molecular mechanisms by which transcription factors regulate the starch metabolism pathway are unclear in maize. Here, we report a transcription factor, ZmMADS1a, that controls starch biosynthesis in maize (Zea mays L.). We demonstrate the expression of ZmMADS1a in tassel, silk, and endosperm, and show that the protein is localized to the cell nucleus. Compared with the control, seeds of overexpressing ZmMADS1a increased starch content (especially amylose content), had smaller starch granules and altered chemical structure. Meanwhile, overexpression of ZmMADS1a resulted in increases in the contents of soluble sugars and reducing sugars in maize. ZmMADS1a plays a positive regulatory role in the starch biosynthesis pathway by up-regulating several starch biosynthesis related genes. We also show that ZmMADS1a has a similar adjustment mechanism of starch biosynthesis in rice. Collectively, our study suggests that ZmMADS1a functions as a positive regulator of starch biosynthesis by regulating the expression of key starch metabolism genes during seed development.
