摘要
DOMESTICATION OF CROPS BY TWO DIFFERENT SCENARIOS Crop domestication is a unique pattern of plant evolution,commonly referred to as the process of generation of cultivated crops from wild specles due to morphological and gen-etic transformation as a result of human intervention and selec-tion.Studies on the relationship between weeds and crops in archaeology,evolutionary biology,and genetics have revolution-ized our understanding of the role of weeds in the agroecosystem and of the intricacy of crop domestication.Weeds,generally be-ing effective competitors of crops,are not the targets of human cultivation;however,like crops,they can adapt to human-made habitats and thereby are under unintentional human selection.The peculiar environment of the agricultural system alows some arable weeds to develop domestication syndrome,Le.,to mimic crop characteristics,such as plant architecture and seed size,to escape being detected and eradicated.
