Silencing of OsiWAK1 affects anther dehiscence and pollen viability in rice. a Flowers of wild type and OsiWAK1-RNAi plants. The length of the anther filament is reduced in OsiWAK1-RNAi plants. b, c Mature and dehiscent anthers of wild type plants (b) and mature and nondehiscent anthers of OsiWAK1-RNAi plants (c). Anthers from opened flowers (left) and closed flowers after anthesis (right) are shown. d Pollen of the wild-type and OsiWAK1-RNAi plants stained with I2/KI. Pollen grains filled with starch granules showed dark blue stain but those with little or no starch stained light yellow with I2/KI
