| occurrence, leaching, and degradation of cry1ab protein from transgenic maize detritus in agricultural streams. | the insecticidal cry1ab protein expressed by transgenic (bt) maize can enter adjacent water bodies via multiple pathways, but its fate in stream ecosystems is not as well studied as in terrestrial systems. in this study, we used a combination of field sampling and laboratory experiments to examine the occurrence, leaching, and degradation of soluble cry1ab protein derived from bt maize in agricultural streams. we surveyed 11 agricultural streams in northwestern indiana, usa, on 6 dates that enco ... | 2017 | 28314135 |
| occurrence of maize detritus and a transgenic insecticidal protein (cry1ab) within the stream network of an agricultural landscape. | widespread planting of maize throughout the agricultural midwest may result in detritus entering adjacent stream ecosystems, and 63% of the 2009 us maize crop was genetically modified to express insecticidal cry proteins derived from bacillus thuringiensis. six months after harvest, we conducted a synoptic survey of 217 stream sites in indiana to determine the extent of maize detritus and presence of cry1ab protein in the stream network. we found that 86% of stream sites contained maize leaves, ... | 2010 | 20876106 |
