YAB transcriptional activity in yeast. Three independently transformed yeast strains expressing Arabidopsis YABs (FIL, YAB2, YAB3, YAB5) or Antirrhinum YABs (GRAM, AmYAB2, PROL) fused to the GAL4 DNA-binding domain (BD) were assayed for MEL1 reporter activity using an X-α-gal plate assay. Colour change after 4 h (+++), after 16 h (++), or no colour change after 24 h (−) are shown.
