French Froggies : New Xenopus plasmids for creating multicellular systems

General Evry Xenopus plasmid schematic

  • We developed and submitted to the registry 3 new plasmid backbones for creating multicellular synthetic systems. They contain a CMV promoter: (ubiquitous expression), an elastase promoter: (pancreas specific), and a Heat-shock promoter: (Heat or stress inducible). All plasmids can be directly injected in to the Xenopus embryo after a miniprep, and are designed for rapid testing of multicellular devices. They contain all sequences necessary for a tissue specific expression, as well as debugging tools. Several plasmids can be co-injected, allowing ratio adjustment and linking the system do modeling. Once the system is tested and debugged, the final system can be implemented by chromosomal insertion.

The auxin system

The auxin emission system

  • K812020:IAAH enzyme that catalyzes the second and last step towards auxin production
  • K812021:IAAM enzyme that catalyses the transformation of Tryptophan to Inodle-3-acetamide
  • K812014:Auxin production cassette containg both enzymes above which is monocystronic

The auxin receiver system

  • K812010:GFP fusion with the ubuquitinase E3 OsTirI recoginition domain which a main part of the degron system
  • K812012:OsTirI Ubiquitinase E3 for AID tagged protein degradation in the presence of auxin
  • K812013:

Reporters and promotors

Summary

In our Project we planned to screen a series of different reporters along with different tissue specific promotors. This was done to validate cross-talk between the emitter-receiver system and and screen various reporters to elucidate the efficiency of different reporters in Tadpole manipulation.

  • K812030:Citrine reporter with a Kozak sequence for eukaryotic expression
  • K812031:sfGFP with kozak sequence for eukaryotic expression
  • K812032:mCFP with kozak sequence for eukaryotic expression
  • K812200:Biobricked pSC2+ plasmid with Elastase promoter for frogs and chicken
  • K812300:Biobricked pSC2+ plasmid with HSP70 promoter for frogs and chicken
  • K812233:sfGFP in pCS2+ downstream to elastase promoter
  • K812331:sfGFP in pCS2+ downstream to HSP70 promoter
