Gibberellic acid (GA) is a phytohormone that is important for plant growth and development. Mutants in GA biosynthesis, signaling and metabolism have been critical to understanding the role GA plays in plants. GA mutants have also revolutionized global production of staple crops such as rice, wheat, and barley. GA mutants have been isolated in maize and characterization of the underlying genes has helped map the GA biosynthesis and signaling pathways. However, the number of maize dwarf mutants is far less than other species. Here, we identify new dwarf mutants that could benefit our understanding of maize plant height control.
赤霉素（GA）是一种对植物生长和发育至关重要的植物激素。GA生物合成、信号传导和代谢方面的突变体对于理解GA在植物中的作用至关重要。GA突变体也彻底改变了水稻、小麦和大麦等主要作物的全球产量。已在玉米中分离出GA突变体，对其相关基因的表征有助于绘制GA生物合成和信号传导途径。然而，玉米矮化突变体的数量远少于其他物种。在此，我们鉴定出了新的矮化突变体，这可能有助于我们对玉米株高控制的理解。
