Summary: The potato root secretes root exudates, a mixture of organic molecules out of which solanine is found in the highest concentration (range of ug/ml). Also, solanine is a molecule specifically found in the root exudate of potato plants, which makes it a good candidate for a dependecy molecule which will ensure that Bacillus mycoides doesn't escape the designated action area. Studies have shown that there are soil bacteria able to metabolize solanine as a carbon source. Unfortunately, we weren't able to find an already described solanine-inducing promoter. Because the natural habitat of B. mycoides is the potato rhizosphere, we have strong reasons to believe that if such a promoter may already be present in its genome. In order to find this promoter, we designed a CHIP-Seq experiment. B. mycoides will be incubated with a different range of solanine concentrations. The DNA will be extracted and the CHIP-Seq technique will be used to detect potential binding sites of solanine operators using monoclonal anti-solanine antibodies.
