\mathfrak{The\:Answer\:is}

The microsporangia, or anthers, are borne on the underside of specialized fertile leaves in short strobili (cones). These leaves often have expanded tips to which the anthers are attached. There are two anthers per fertile leaf in many conifers but in some there are more. The cones themselves are produced in the axils of scale-leaves in pines, or at the tips of lateral shoots in other families.

Answer:

The Norway spruce MADS-box genes DAL11, DAL12 and DAL13 are phylogenetically related to the angiosperm B-function MADS-box genes: genes that act together with A-function genes in specifying petal identity and with C-function genes in specifying stamen identity to floral organs. In this report we present evidence to suggest that the B-gene function in the specification of identity of the pollen-bearing organs has been conserved between conifers and angiosperms
