In situ expression of PnTgs1-like in reproductive tissues of sexual (Q4188) and apomictic (Q4117) Paspalum notatum genotypes at late premeiosis/meiosis. Sexual genotype Q4188 reproductive tissues (ovaries + anthers) hybridized with an antisense PnTgs1-like RNA probe, showing expression mainly in the ovule (A, B, C). Larger images of ovules originated from sexual genotype Q4188 (D, E, F). Apomictic genotype Q4117 reproductive tissues (ovaries + anthers) displaying a lower expression of PnTgs1-like (G, H, I). Larger images of ovules originated from apomictic genotype Q4117 (J, K, L). White dotted lines indicate ovule boundaries. OV: ovule; MMC: megaspore mother cell; AI: apospory initials. Bars: 50 μm.
