TEF1p-SPE1-PRM9t

TEF1p-SPE1-PRM9t:

This composite part was created by fusion PCR and used to exogenously express SPE1 gene and results in the overexpression of putrescine. This part was used in the oaz1Δ strain, in which the polyamine synthesis flux is stronger. We investigate whether this part can confer thermo-tolerance to resulted strain.

ppppppppppppp

Using the OAZ1 knockout strain we previously constructed, we generated yeast expression plasmids to overexpress SPE1, to achieve overexpression of thermospermine. We initially obtained the plasmid backbone through PCR (Figure 1: 7-1 to 7-4) and the insert fragments (Figure 1: 7-5 is TEF1p-SPE1-PRM9t). Subsequently, we used homologous recombination to construct the complete plasmids and validated their successful construction through sequencing (Figure 2).

Then we tested the growth of these strains under 35°C conditions (Figure 3). The results indicate that the expression of the SPE1 gene did not have a significant impact on the yeast's thermo-tolerance capabilities.
