ETT 388–594 is the auxin-responsive domain. (A) Schematic representation of ETT variants and their behaviour in Y2H assay in combination with IND and in the absence and presence of auxin at different concentrations. Clones EP1, 2 and 3 were isolated from a random mutagenesis analysis of the ES domain; clones called ES_SP, referring to the Ser patch, are serine to threonine mutations introduced by site-specific mutagenesis.

(GJ) Mapping and optical microscopy images of gynoecium of Brassica rapa wild type (G) and ett mutant: BraA.ett.a Stop220 (I) and BraA.ett.a Gln480Stop (J).
