Fig. 1. Wild-type (Ler), duet and revertant plants. (A) Wild-type
plant showing normal elongating siliques. (B) duet mutant plant with
short siliques. (C) Mutant plant with revertant sector showing elongating
silique (arrow). (D) Wild-type flower with long anther filaments and plentiful
pollen. (E) duet flower with short filaments and anthers lacking
pollen. (F) Wild-type cDNA and derived amino acid sequence of DUET
near the site of the Ds insertion. The duet mutant sequence shows a 8
bp duplication (bold underlined). The two excision alleles have a 7 and 8 bp
footprint respectively (bold).
