Researchers from the Salk Institute used the latest DNAsequencing technologies to study exactly what happens at a molecular level when new genes are inserted into plants. Scientists usually rely on Agrobacterium tumefaciens when they want to put a new gene into a plant. Decades ago, scientists discovered that when the bacteria infected a tree, it transferred some of its DNA to the tree’s genome. Since then, researchers have co-opted this transfer ability of Agrobacterium for their own purposes, using its transfer-DNA (T-DNA) to move a desired gene into a plant. Recently, DNA sequencing technologies started to hint that when the Agrobacterium T-DNA is used to insert new genes into a plant, it may cause additional changes to the structural and chemical properties of the native DNA.
