Association of Xa13 expression and pollen development.Bars, 30 μm. (Bp) Bicellular pollen grain; (D) dyad; (Dp) degenerated pollen grain; (E) epidermis; (En) endothecium; (Ml) middle layer; (Up) unicellular pollen grain; (T) tapetum; (Tp) tricellular pollen grain; (V) vascular element; (W) anther wall.
Pollen development at different stages in wild-type Minghui 63 and Xa13-suppressed T0 plant D75RMH2, showing that there is no apparent difference between the wild-type and transgenic plants at the unicellular pollen grain stage, whereas various abnormalities are observed at bi- and tricellular pollen grain stages.
(B) Expression of Xa13 in anthers of wild-type Minghui 63 and T0 plants D75RMH2 and D75RMH5 examinedby in situ hybridization. The dark blue color in the pollen grains, the cells of anther wall, and the connective vascular element indicates hybridization of Xa13 transcripts.
