摘　　要：Dear Editor,Weedy rice(Oryza spp.)is a problematic paddy weed known for traits such as high seed shattering,persistent seed dormancy in the soil seed bank,and robust competitiveness against cultivated varieties,threatening rice production yields worldwide(Nadir et al.,2017).Recent population genomics studies have shown that weedy rice strains around the world have repeatedly and independently evolved from various cultivated ancestors at different times in the history of rice cultivation(Li et al.,2017;Qiu et al.,2017;Sun et al.,2019).This de-domestication(feralization)process involves phenotypic reversions from key domestication traits,such as non-shattering and non-dormant seeds,to more wild-like characteristics.Diverse genetic mechanisms appear to underlie the convergent evolution of weedy rice worldwide(Qi et al.,2015;Qiu et al.,2020).While most global weedy rice directly descends from domesticated rice,introgression from wild rice also contributes to its adaptive evolution,particularly in tropical Asia where wild Oryzas occur(Li et al.,2024a).
