Proof of concept in fungi
Several separate devices were conducted with Plug ‘n’ Play assembly to verify if the system will work in fungi as well as in mammalian cells. The idea was to target the fungi with a fluorescence protein to specific compartments and in general to express the fluorescence proteins. All the devices have the same promoter, terminator and marker cassette, though with different gene of interest and were all transformed in laboratory
Aspergillus nidulans stain:
argB2, pyrG89, veA1 by random non-homologues-end-joining integration.
We succeed in proving that Plug ‘n’ Play assembly easily transformed and expressed in fungi as we succeed in tagging A. nidulans with two fluorescence proteins. The transformants with integration of our 4 devices change morphology compared with the wild type control strain since the DNA were randomly intergraded and have inflicted some pathways in the fungi.
The results are displayed in the following section.
Device 22
The results shows fluorescence spread evenly in the hyphae which correlate with that in device 22, the gene of interest, only consists of a green fluorescence protein GFP with no specific target.

Device 23
The results shows fluorescence spread evenly in the hyphae and with spots of fluorescence. Device 23 consists of GFP with a target signal to the peroxisomes which can explain the spots compared to the results from device 22. We cannot conclude that the signal is accumulated in the peroxisomes since they are not dyed, though can it be concluded that the GFP signal is target a specific place and accumulated somewhere in the fungi compared to the results from device 22.
