Effects of Transgenic Rice with Genes cry1C and cry2A on Species Diversity of Zooplankton Community in Paddy Fields
摘要
Abstract
In the current study,we investigated the potential effects of transgenic Bt rice on the zooplankton community in rice paddy fields.crylC transgenic rice (T1C-19),cry2A transgenic rice (T2A-1),and their non-transgenic parental rice Minghui63 (MH63) were evaluated for the zooplankton species and community diversity at different growing stages.The numbers of zooplankton fluctuated obviously in rice paddy fields at different growing stages,with the Shannon-Wiener diversity and evenness indexes reaching the highest levels at the elongation stage.During the booting stage,pesticides had to be used to control locust infestation,which caused the numbers of zooplankton,Shannon-Wiener diversity and evenness indexes to decline throughout the rest of the growing stages.However,no significant differences in the diversity and quantity of zooplankton species were found between fields planted with transgenic Bt rice and non-transgenic Bt rice at all growing stages.Our results show that the use of pesticides,but not the introduction ofBt gene,has negative effects on the zooplankton community in rice paddy fields.关键词
