HIRA is epistatic to HUB1 and RDO2/TFIIS. (a,b) Germination of freshly harvested seeds of Col 0 (black), hub1-5 (red), rdo2-2 (dark blue), hira-1 (grey), hub1-5 hira-1 (orange) and rdo2-2 hira-1 (light blue) at 10 °C (seed viability test; a) or at 25 °C (dormancy test; b) in darkness. Means of biological triplicates with SEM are shown. Statistically significant differences relative to dry seeds were determined using a two-sided Student’s t-test (a = p < 0.01 relative to Col 0; b = p < 0.01 relative to hub1-5; c = p < 0.01 relative to rdo2-2).
