...The above are not requirements for gene flow, but they may significantly affect the frequency of flow and probability of introgression (Jenczewski et al., 2003)....

...The extent of this overlap can indicate the likelihood of hybridization (Jenczewski et al., 2003)....

...Therefore, plants that may normally fall outside of the necessary proximities and compatibilities are not definitively denied access to genes, but they may receive them less frequently (Jenczewski et al., 2003)....

...…from previous studies: 1) the frequency of gene flow that allows transgenes being transferred to wild populations; 2) the fitness of early hybrids relative to their wild parents, and 3) possible fitness costs or benefits that are associated with a particular transgene (Jenczewski et al., 2002)....

...For the estimation of long-term persistence and spread of transgenes in wild rice population in relation to the fitness change, three key factors should be take into consideration, given that knowledge of the close genetic relationships and high compatibility among the AA-genome Oryza species are obtained from previous studies: 1) the frequency of gene flow that allows transgenes being transferred to wild populations; 2) the fitness of early hybrids relative to their wild parents, and 3) possible fitness costs or benefits that are associated with a particular transgene (Jenczewski et al., 2002)....

...Note that mating systems and differences in ploidy levels are not the only reproductive barriers that can limit crop-to-wild gene flow (see Arnold, 1997; Rieseberg, 1997; Rieseberg and Carney, 1998 for review)....

...The presence of either unreduced gametes or endomitosis after fertilization leads to production of fertile allopolyploid F1 hybrids containing each of the parental genomes at the diploid stage (Bretagnolle and Thompson, 1995; Ramsey and Schemske, 1998)....

...The resulting triploid hybrids are not as systematically sterile as previously considered; some of them are able to produce euploid gametes and can thus serve as a bridges for gene flow or the formation of new polyploid species (Ramsey and Schemske, 1998)....

...Detailed reviews have recently addressed the mechanisms controlling polyploidization (Bretagnolle and Thompson, 1995; Ramsey and Schemske, 1998) and hybrid speciation (Rieseberg, 1997)....

...Although introgression between wild and domesticated plants is suspected to be widespread (De Wet and Harlan, 1975; Harlan, 1992; Rieseberg and Wendel, 1993; Ellstrand et al., 1999), it has rarely been demonstrated in wild populations (Luby and McNicol, 1995; Whitton et al., 1997; Linder et al.,…...
