The CDKD;1, CDKD;2, CDKD;3, and CDKA;1 reporter constructs are fully functional. (A) Phenotypes of cdkd;2/− cdkd;3/− double mutants and cdkd;2/− cdkd;3/− double mutants containing a CDKD;2 and CDKD;3 reporter, respectively, in comparison with WT. Photographs were taken 5 wk after sawing. Scale bar, 3 cm. (B) Inflorescences of the cdkd;2/− cdkd;3/− double mutants and the CDKD;2 and CDKD;3 reporter lines (in a cdkd;2/− cdkd;3/− mutant background) in comparison with WT plants of the same age. Photographs were taken 14 wk after sawing. Scale bar, 7 cm. (C) Siliques of WT, the CDKD;2 and CDKD;3 reporters in a cdkd;2/− cdkd;3/− mutant background, and the CDKD;1 reporter in a cdkd;1/− cdkd;3/− mutant background versus cdkd;1/−cdkd;3/+ double mutants, which have a high level of seed abortion, indicated by red asterisks. Scale bar, 1 mm. (D) The main stem and siliques of the CDKD;1 reporter line in a cdkd;1/−cdkd;3/− background versus cdkd;1/−cdkd;3/+ double mutant. Scale bar, 3 cm. (E) Peterson staining of anthers for WT, CDKD;1, CDKD;2 and CDKD;3 reporter lines in the indicated cdkd mutant background. Scale bar, 20 µm. (F and G) Chromosome spread analysis of CDKA;1:mTurquoise2 in cdka;1/− (F) versus cdka;1/− D mutant (G). Scale bar, 10 µm.
