Fig. 6.
Expression pattern of the three Arabidopsis PDI-C gene promoters during flowering and seed formation. The GUS staining pattern of PDI7 pro:GUS (a, d, g) PDI12 pro:GUS (b, e, h), and PDI13 pro:GUS (c, f ,i) at the floral shoot apex (a–c), in mature flowers (d–f), and green siliques showing developing seeds (g–i). Arrows indicate expression in filaments (f), in pollen of anthers (po) and the style (sy). The images were derived from at least three independent experiments of with a minimum of 10 independent transgenic lines per construct. Scale bar 1 mm
