Evolutionary Genomics of Weedy Rice in the USA 总被引:8,自引:0,他引:8

Red rice Is an Interfertlle, weedy form of cultivated rice (Oryza sativa L.) that competes aggressively with the crop In the southern US, reducing yields and contaminating harvests. No wild Oryza species occur In North America and the weed has been proposed to have evolved through multiple mechanisms, Including "de-domestication" of US crop cultlvars, accidental introduction of Asian weeds, and hybridization between US crops and Asian wild/weedy Oryza strains. The phenotype of US red rice ranges from "crop mimics", which share some domestication traits with the crop, to strains closely resembling Asian wild Oryza species. Assessments of genetic diversity have Indicated that many weed strains are closely related to Asian taxa (Including indica and aus rice varieties, which have never been cultivated In the US, and the Asian crop progenitor O. ruflpogon), whereas others show genetic similarity to the tropical Japonica varieties cultivated In the southern US. Herein, we review what Is known about the evolutionary origins and genetic diversity of US red rice and describe an ongoing research project to further characterize the evolutionary genomlcs of this aggressive weed. 相似文献

<正>A starting point of curating bioinformatic resources for the public is marked by the establishment of the US National Center for Biotechnology Information(NCBI)in 1988[1].One of its many purposes is certainly to echo the initiative of the Human Genome Project(HGP)––when two landmark reports were published at the same time:‘‘Mapping and Sequencing the Human Genome’’by the National Research Council[2]and‘‘Mapping Our Genes––The Genome Project:How Big,How Fast?’’by the US Congress[3]. 相似文献
