Higher plants display a variety of architectures that are defined by the degree of branching, internodal elongation, and shoot determinancy. Studies on the model plants of Arabidopsis thaliana and tomato and on crop plants such as rice and maize have greatly strengthened our understanding on the molecular genetic bases of plant architecture, one of the hottest areas in plant developmental biology. The identification of mutants that are defective in plant architecture and characterization of the corresponding and related genes will eventually enable us to elucidate the molecular mechanisms underlying plant architecture. The achievements made so far in studying plant architecture have already allowed us to pave a way for optimizing the plant architecture of crops by molecular design and improving grain productivity.
高等植物呈现出多种结构,这些结构由分支程度、节间伸长和茎尖确定性所定义。对拟南芥和番茄等模式植物以及水稻和玉米等作物的研究极大地加深了我们对植物结构分子遗传基础的理解,而植物结构是植物发育生物学中最热门的领域之一。鉴定在植物结构上有缺陷的突变体并对相应及相关基因进行表征,最终将使我们能够阐明植物结构背后的分子机制。到目前为止,在研究植物结构方面所取得的成果已经使我们能够为通过分子设计优化作物的植物结构和提高谷物产量铺平道路。
