“…On the other hand, Cry proteins may be readily degraded (Wang et al, 2007;Liu et al, 2018b). In a study with the same rice cultivar (Huahui-1), the authors suggest that Cry1Ab/Ac proteins could not be detected in irrigation water of the rhizotrons (Liu et al, 2018a).…”

“…However, the Cry1Ab/Ac of Bt rice can enter soil ecosystems through root exudations, pollen and plant residue inputs, and thus nematodes are likely to be exposed to bioactive proteins from transgenic Bt rice because of their trophic position in soil food webs (Ruf et al, 2013). Moreover, the Cry1Ab/Ac proteins of Bt rice might accumulate in rhizosphere soil (Liu et al, 2018a). However, no definite conclusions have been drawn about whether Bt rice can negatively affect soil nematode.…”

The wide-scale adoption of transgenic crops has aroused public concern towards potential impacts to the ecological services of soil fauna, such as soil nematodes. However, few studies has examined whether the cultivation of transgenic rice would pose greater threats to soil nematode community and associated ecological functions than insecticides application. Moreover, what are determinants of soil nematode community in paddy fields remains unclear. During a 3-year field study, rhizosphere soil samples of transgenic-Bt rice, its counterpart non-Bt parental rice and not-Bt rice with insecticides application were taken at four times in the rice developmental cycle using a random block design with three replications for each treatment. We hypothesized that the effects of pest management practice on soil nematode abundance and metabolic footprint change with trophic group and sampling time. We also predicted there were significant differences in structure and composition of soil nematode community across the three treatments examined and sampling times. In agreement with our expectation, the effects of pest management practice on nematode abundance and metabolic footprints depend on trophic group and sampling time. However, pest management practice exerted no apparent effect on nematode diversity and community composition. Soil nutrient availability and C:N molar ratio are the primary regulating factor of soil nematode community in rice paddy fields. In conclusion, our findings implied that changes in abundance, diversity, metabolic footprints associated with the crop growth stage overweighed the application of Bt rice and insecticides. The cultivation of Bt rice Huahui-1 exerted no measurable adverse effect on soil nematode community in rhizosphere soil over 3 years of rice cropping.
