Experiment with snails:
Let both N. benthamiana leafs with snails overnight at room
temperature in separated boxes. We will observe if snails eat the leafs
and if appears fluorescence.

Experiment is over due to snails haven’t eaten leafs enough so
we have not been able to see fluorescence.

works but we must optimized it to increase the signal range. In
this way, we will be able to distinguish signal from
noise.

Eliminate 5’ region of the devise
Change linker sequence
Add renilla in luciferase assay
Change reporter to +1
