ObjectiveIn this experiment, a region of the neural crest will be transplanted from one stage-fourteen embryo to another (Figure 1). To facilitate the visualization of the grafts and observe the cell fates of the tranplanted region, both albino and wild type embryos will be used. Ten transplants will be attempted in which a region of an albino embryo neural crest will be tranplanted into the regularly pigmented wild-......閱讀全文

到2050年,全球人口將達到97億,預計作物產量翻一番才能滿足全球人口的糧食需求。為了達到這一目標,作物產量需每年增長2.4%,但目前作物產量平均增長率僅為1.3%。作物生產性能的遺傳改良仍然是提高作物生產力的關鍵因素,但當前的改善速度無法滿足可持續性和糧食安全的需要。為了確保糧食安全、生態系統的可
