Introgression from genetically modified plants into wild relatives.

Book cover for Introgression from genetically modified plants into wild relatives.

Description

Introgression is the incorporation of a gene from one organism complex into another as a result of hybridization. A major concern with the use of genetically modified (GM) plants is the unintentional spread of the new genes from cultivated plants to their wild relatives and the subsequent impacts on the ecology of wild plants and their associated flora and fauna. The book reviews these issues, foc...

Chapter 11 (Page no: 139)

Crop to wild gene flow in rice and its ecological consequences.

Gene flow is the major pathway for transgene escape from crops to their wild relatives (including weedy biotypes). Transgenes that spread to and persist in the environment will probably lead to ecological consequences. Those genes that resist biotic and abiotic stresses could considerably enhance ecological fitness of the wild relative species, causing unwanted environmental consequences. If transgenic crop varieties are released into the environment, transgene escape to wild relatives through outcrossing will probably occur. In the origin and diversity centres of crop species and their wild relatives, the possibility of transgene escape to the wild species will be high and, as a consequence, the ecological impact of transgene escape might also be great. It is generally understood that the possible crop to wild transgene escape must satisfy three conditions, these are: (i) spatially, transgenic crops and their wild relatives should have an overlapping distribution and be in close contact; (ii) temporally, the flowering time of transgenic crops and their wild relatives should coincide; and (iii) the transgenic crop and the target wild relative species should have sufficiently close biological relationships and insufficient reproductive barriers. This chapter presents studies of crop to wild gene flow in rice based on data of geographical distribution, flowering habit, interspecific hybridization and gene flow from cultivated rice (Oryza sativa) to its closely related wild relatives, to estimate the opportunity for crop to wild transgene escape. The general expectations of transgenic escape in rice are also discussed in terms of its potential ecological consequences.
