Obtaining the fragment and BsaI digested verification

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

We construct tENO2 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 tENO2(238bp) matched with previous expectations by compared with Marker MK8000 ladder, confirming the successful assembly of Toolkit plasmids and availability in subsequent construction.

. The initiation of the CsF3H sequence is done by promoter pGAL7, with termination done by tENO2. The sequence ConL1 and ConR2 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.

tENO2 is also involved in assembly of synthesis pathway of catechin, shown by Fig.3.
