Weeds,especially close relatives of crops,pose severe threats to agricultural production worldwide.As an evolutionary"evil twin"of cultivated rice,weedy rice(Oryza sativa f.spontanea)has emerged as a pernicious weed that evolved with strong growth and reproductive advantages,such as easy seed shattering and long seed dormancy,strong competitiveness for depriving resources,and robust environmental adaptability,to outcompete cultivated rice in the paddy field(Figure 1).
