| transgenic soybean pollen (glycine max l.) in honey from the yucatán peninsula, mexico. | using precise pollen species determination by conventional microscopic methods, accompanied by molecular genetic markers, we found bees collect gmo (genetically modified) soybean pollen and incorporate it in yucatan honey. honey comb samples from las flores, campeche, mexico, often contained soybean pollen. pollen in honey was analyzed in nine samples; six contained substantial soy pollen and two tested positive for soybean gmo. our analyses confirm field observations that honey bees, apis melli ... | 2014 | 24503936 |
