In situ localization of PrMADS3 transcripts in developing SCBs, PCBs, and DSBs. a, Differentiating SCB. Expression in the group of cells initiating ovuliferous scale primordia is shown by arrowheads (magnification ×42). b, Cross-section of differentiating SCB. Expression in the group of cells initiating ovuliferous scale primordia is shown by arrowheads (magnification ×45). c and d, SCB at stage 2. Ovuliferous scale primordia shown by arrowheads (magnification ×100 and ×11.25, respectively). e, Cross-section of SCB at stage 3. Ovuliferous scale primordia shown by arrowheads (magnification ×55). f and g, SCB at stage 3 (magnification ×45 and ×8.3, respectively). h, DSB with initiating needle primordia (arrowheads) (magnification ×90). i, DSB with developing needle primordia (arrowheads) (magnification ×45). j and k, Differentiated PCB with initiating microsporophylls (stage 1). Two layers of tapetal cells surrounding pollen mother cells are shown by arrowheads (magnification ×45 and ×60, respectively). l, PCB after completion of microsporophyll initiation (stage 2) (magnification ×23.5). All sections except b and e, which are cross-sections, are longitudinal. ap, Apical meristem; bp, bract primordia; mi, microsporophylls; pmc, pollen mother cells; sc, sterile cataphylls; and spc, sporogenous cells.
