From: Identification of transcription-factor genes expressed in the Arabidopsis female gametophyte
Expression patterns of transcription-factor promoter:cGFP fusions in the female gametophyte. (A) pAT2G22750:cGFP expression in the antipodal cells. (B) pAT1G49770:cGFP (ZOU/RGE1) expression in the central cell and the synergid cells. (C) pAT5G11050:cGFP (MYB64) expression in the central cell, the egg cell, and the synergid cells. (D) pAT1G75250:cGFP (RL6) expression in the central cell, the egg cell, and the synergid cells. Each panel contains an epifluorescence image (top) and an overlay (bottom) of the epifluorescence and a bright-field image of the same ovule. Images in (A) were taken at the developmental stage FG5, the rest of the images were taken at stages FG6 to FG7 [63]. ac, antipodal cells; cc, central cell; ec, egg cell; sc, synergid cell. Scale bars: 50 μm.
