花粉介导的基因流动是转基因水稻向其野生近缘种逃逸的主要途径，如果将转基因水稻释放到具有AA基因组的野生稻环境中，转基因可能会在基因流动后的野生群体中持续存在并传播，从而造成不良的生态后果。为了评估转基因逃逸所造成的潜在后果，了解转基因水稻到野生近缘种的实际基因流动频率、转基因在野生近缘种中的表达和遗传是很重要的。本文综述了转基因水稻通过基因流向其野生近缘种逃逸及其生态后果的研究进展，并在此基础上探讨了转基因水稻向其野生近缘种逃逸的潜在生态后果的评估框架。(C)2009 Elsevier Inc. All rights reserved.
Pollen-mediated gene flow is the major pathway for transgene escape from GM rice to its wild relatives Transgene escape to wild Oryza species having AA-genome will occur if GM rice is released to environments with these wild Oryza species Transgenes may persist to and spread in wild populations after gene flow, resulting unwanted ecological consequences. For assessing the potential consequences caused by transgene escape, it is important to understand the actual gene flow frequencies from GM rice to wild relatives, transgene expression and inheritance in the wild relatives. as well as fitness changes that brought to wild relatives by the transgenes This article reviews studies on transgene escape from rice to its wild relatives via gene flow and its ecological consequences A framework for assessing potential ecological consequences caused by transgene escape from GM rice to its wild relatives is discussed based on studies of gene flow and fitness changes.
