Obtaining the pTEF1 fragment and BsaI digested verification

Figure 1: [1] Results of yeast toolkit plasmids enzyme-digested verification

We construct pTEF1 with vector type8-pSB1K3-GFP and proceed digested verification using BsaI. According to Fig.1, we obtain two clear bands after BsaI digested, the length of the vector(1622bp) and the inserted fragments pTEF1(709bp) matched with previous expectations by compared with Marker MK8000 ladder, confirming the successful assembly of Toolkit plasmids and availability in subsequent construction.

pTEF1 in Level1 plasmid assembly

Figure 2: [2] A: the construction strategy; B: results of colony PCR; C: results of sequencing analysis of coding sequence GbCHS

The construction schematic of GbCHS sequence demonstrated as Fig.2. The initiation of the GbCHS sequence is done by promoter pTEF1, with termination done by tADH1. The sequence ConL2 and ConR3 are connector sequences within the Level 1 plasmid assembly. Furthermore, typr9-KVF and type9-VR are imposed to enact selection through colonies PCR, results shown in Fig.2 The band length 2500bp match with expectations. The sequence analysis results show no significant mutations or deletions, representing the success of the assembly.

pTEF1 is also involved in assembly of synthesis pathway of naringenin, shown by Fig.3.
