Toehold for Fusarium oxysporum 4

Toehold switches are RNA tools used for the detection of a sequence of interest. They're composed of four main parts: the first part is located at the beginning of the toehold and it is complementary to a given sequence of interest also called trigger; next, there is a hairpin-like sequence, which hides an RBS and start codon; subsequently, at the end of the hairpin, a linker sequence is used as a spacer before the next component; finally, a coding sequence for a reporter gene of choice is added after the toehold design (not present in this part). This toehold is functional at a temperature of 37°C for the detection of Fusarium oxysporum (28S-18S ribosomal RNA intergenic spacer), has a MFE of -36.40000153 (kcal/mol) and was designed using the software Toehold Switch Creator by the Tec-Monterrey 2021 team.

Usage and Biology

In order to have a more graphical approach of the comparison of the structures, we obtained an image of the secondary structure of the toeholds using the NUPACK package.
