A.  aAssessing gene flow from Bt cotton in Brazil and its possible consequences.h[electronic resource]  c2006  a261-299. v.2.  a(Environmental risk assessment of genetically modified organisms series, v. 2).vv.2.  aCapítulo 11: Introduction. Factors that affect the likelihood of gene flow: evolutionary and taxonomic background; taxonomy of the Gossypium species indigenous to Brazil; non-Gossypium relatives of cotton and their potential role in Bt gene escape; Gossypium populations in Brazil; occurrence of Gossypium in the three cotton-growing regions of Brazil; reproductive isolation among Brazilian Gossypium species; What would it take to isolate crops and prevent gene flow? Likelihood of transgene establishment and spread: regional differences in insect pressure will change fitness effect of Bt gene; other factors that affect establishment and spread of transgene. Consequences of gene flow. Staging the risk-assessment process: pre-transformation: consideration of crop biology and distribution of recipient populations; posttransformation, prerelease: gene flow and introgression for crop and local recipient populations; small-scale field trials; large-scale testing and release: monitoring and mitigating gene flow. Overall conclusions. References. Glossary of terms.  aBrazil  aAlgodão Bt1 aMALLORY-SMITH, C.1 aBRUBAKER, C. L.1 aGANDARA, F.1 aARAGÃO, F. J. L.1 aBARROSO, P. A. V.1 aQUANG, V. D.1 aCARVALHO, L.
