Potential effects of Bt transgenic rice on soil micro-ecosystem

Abstract

Abstract: With the increasing commercial use of genetically modified crops (GMCs),it is quite important to assess their potential ecological risk.The likelihood of genes dispersal from GMCs to related wild species,the tolerance of insects to insect-resistant GMCs,and the potential impact of GMCs on biodiversity have been extensively investigated.This article reviewed the potential ecological risk assessment of transgenic Bt rice-expressed products,including the persistence characteristics of Bt insecticidal crystal proteins in soil,and their effects on soil culturable microbial flora and soil enzyme activities,which could provide useful information for related researches.

Key words: Transgenic Bacillus thuringiensis (Bt) rice, Bt insecticidal crystal proteins, Ecological safety, Soil micro-ecosystem
