Yeast One Hybrid Services Core


The purpose of the Yeast One Hybrid Services Core is to carry out high-throughput mating-based yeast assays to screen for protein (transcription factor) – DNA (promoter or regulatory region) interactions. These gene-centered assays start with a DNA regulatory region of interest and enable identification of transcription factor(s) that interact with this region.

The Yeast One Hybrid Services Core provides a screening service between promoters and collections of Arabidopsis or Maize transcription factors.


Three collections of transcription factors are available:

i.  A root stele-expressed collection of 800 Arabidopsis transcription factors (Gaudinier, Zhang et al. 2011; Li, Gaudinier et al. 2014) TFLIST 12-10-2014 CLM-1 (-850 root expressed TFs);

ii.  A complete collection of 2,000 Arabidopsis transcription factors (Pruneda-Paz, Breton et al. 2014) TFLIST 11-30-2015 (full Arabidopsis TF collection)

iii.  A collection of 500 maize transcription factors (Burdo, Gray et al. 2014) Maize TF Master list 3-2016.

These constructs will then be provided to the UC Davis Yeast One Hybrid Services Core. The UC Davis Yeast One Hybrid Services Core completes yeast transformation, auto-activation tests, genotyping, and mating-based screens. Positive interactions are recorded for LacZ and HIS3 reporters.
