Abstract

In this study, Bt transgenic rice (KMD rice) residue decomposition and the associated microbial community in a rapeseed-rice cropping system were assessed in comparison with its parental non-Bt rice variety (XiuShui 11). Decomposition was measured as mass loss by straw and root decay in litterbags over two consecutive years. Bacterial and fungal community compositions associated with residue decomposition were detected by terminal restriction fragment length polymorphism (T-RFLP) and the additive main effects multiplicative interaction (AMMI) analysis model. Decomposition dynamics and bacterial and fungal communities associated with decomposition were strongly affected by surface and incorporated placements, and by temporal factors. However, no significant differences were observed between Bt and non-Bt rice variety in either decomposition dynamics or in the soil microbial communities associated with residue decay. Our field study indicated that the insertion of the cry1Ab gene into Xiushui 11 rice genome had no significant effect on the residual decay and decomposition-associated microbial community compositions in the rapeseed-rice cropping system. © 2010 Springer Science+Business Media B.V.
