春季种植后,玉米植株常常遭受洪涝灾害,这大大降低了种子萌发及其出苗率,最糟的是洪涝灾害后,很可能整个田间需要重新种植。对此,美国农业部农业研究局的遗传工程学家Many Sachs及伊利诺依大学研究人员正在研究玉米植株对由于洪涝引起的缺氧的基因是如何反应的。 Sachs发现,萌发籽苗通过快速抑制正常蛋白合成而作出反应。然后,它选择性地合成约 After spring planting, corn plants often suffer from flooding, which greatly reduces seed germination and its emergence rate. The worst is that after a flood disaster, it is likely that the entire field needs to be replanted. In response, Many Sachs, a genetic engineering scientist at the USDA’s Agricultural Research Service and researchers at the University of Illinois, are investigating how maize plants react to hypoxia-causing genes due to flooding. Sachs found that germinating seedlings respond by rapidly inhibiting normal protein synthesis. Then, it selectively synthesizes approx
