Tissue-specific expression of a COI1-YFP transgene rescues coi1 sterility. (A) coi1 plants expressing a LTPpro::COI1-YFP gene show the YFP signal only in epidermal cells of the filament and anther. (B) In the transgenic plants, filament elongation, anther dehiscence (left), and pollen-tube germination and growth (right) are all sufficient to restore fertility, although (C) filament elongation and anther dehiscence are delayed compared to wild type.
