Bt brinjal from non-transgenic, and "aad" is used to identify the transformed bacteria used during the development of the construct. "Aad" contains a bacterial promoter and is not expressed in the Bt brinjal. The completed construct was inserted into young cotyledons from the brinjal plants using an "Agrobacterium"-mediated technique. "Agrobacterium" naturally inserts DNA into plants from its Ti plasmid, and scientists use this to insert genes of interest into various plants. The transformed plants were regenerated and analyzed for the presence of the gene through Southern blotting. The plants' progeny were also analyzed to identify lines segregating in a Mendelian fashion. When
Fruit and vegetable wash Food and Drug Administration nor the United States Department of Agriculture recommend washing fruits and vegetables in anything other than cold water. To date there is little evidence that vegetable washes are effective at reducing the presence of harmful microorganisms, though their application in removing simple dirt and wax is not contested. Fruit and vegetable wash A vegetable wash is a cleaning product designed to aid in the removal process of dirt, wax and pesticides from fruit and vegetables before they are consumed. All fresh produce, even organic, can harbor residual pesticides, dirt or harmful microorganisms on the surface. Vegetable
