Fig. 2: Endosperm cellularization is not affected in BR mutants.

a–d Seeds of Col-0 (a), det2-1^−/− (b), En-2 (c) and bri1-6^−/− (d) at 4 DAP with no visible cellularization; e–h Seeds of Col-0 (e), det2−1^−/− (f), En-2 (g) and bri1-6^−/− (h) at 5 DAP with visible cellular endosperm; i–l Seeds of Col-0 (i), det2-1^−/− (j), En-2 (k) and bri1-6^−/− (l) at 6 DAP with cellular endosperm around the embryo or further developed; m–p Seeds of Col-0 (m), det2-1^−/− (n), En-2 (o) and bri1-6^−/− (p) at 7 DAP with cellular endosperm; q–t Seeds of Col-0 (q), det2-1^−/− (r), En-2 (s) and bri1-6^−/− (t) at 8 DAP with endosperm cellularization ongoing or almost completed. Arrows point to cellular endosperm. Dashed lines delimit endosperm cellularization. Scale bars, 50 μm. These experiments were repeated twice with similar results.
