After the first rejection, I totally revised the grant:
1. I wrote it in English (the first version had been in German)
2. Included only Aplysia (the first one had been on Aplysia and Drosophila)
3. Replaced an imaging study (which I had learned might be difficult in Aplysia) with some molecular biology (I have an expert in the method here at the institute)
4. Wrote a detailed work plan which not only contained which experiments would be conducted in what year, but also the division of labor for the experiments.
5. Backed every experiment up with a "Plan-B-Experiment", in case something would go wrong in the first try. This was to safeguard the project and the graduate student carrying it out from failure.

Thus, basically the only thing left from the first version were some physiological experiments at the end of the project.

The main reasons for the rejection were
1. That I had just resubmitted the original grant
2. That I hadn't published in the past year (the one I was without funding, because my first grant was rejected), despite one paper was submitted and another is in preparation.

Is this borderline fraudulent or is this already crossing the border?
