WebbA typical male flower consists of a central axis bearing numerous spirally-arranged sporophylls (stamens), each of which consists of a slender stalk (filament) terminating distally in a more or less prominent knob or triangular scale, and bearing two or more pollen-sacs (microsporangia) on its lower surface. 1 2 WebbStamen specification and anther development involve a number of extraordinary events such as meristem transition, cell division and differentiation, cell-to-cell communication, etc., which need the cooperative interaction of sporophytic and gametophytic genes [22]. All these stages can be expediently experimented under in vitro conditions.
