Fig. 2. H2B.8 is required and sufficient to drive chromatin and nuclear condensation.

Fig. 2

a, Sperm nuclear sizes in WT and other indicated genotypes. P values calculated using one-sided ANOVA followed by individual two-sample Tukey tests. Boxplots marked as A and B are significantly different between groups (P < 0.001) but not within the group (P > 0.1). n = 80 (WT, h2b.8-1, pH2B.8::H2B.8–Myc h2b.8-1, pH2B.8::H2B.8-N234K–Myc h2b.8-1), 79 (pH2B.8::H2B.8–eGFP h2b.8-1, h2b.8-2) or 39 (pH2B.8::H2B.8ΔIDR–eGFP h2b.8-1) nuclei examined over two independent experiments. b,c, Super-resolution 3D-SIM images (left) and associated intensity profiles (right) of sperm and seedling nuclei of indicated genotypes (h2b.8 refers to h2b.8-1 unless specified otherwise). Data shown represent three independent experiments. Scale bars, 1 μm (b), 1 μm (c, upper two panels) and 2 μm (c, lower three panels). d, Root nuclear sizes in indicated genotypes (numbers after the genotype indicate independent transgenic lines). P values calculated using one-sided ANOVA followed by individual two-sample Tukey tests. Boxplots marked as A and B are significantly different between groups (P < 0.05) but not within the group (P > 0.1). n = 100 (WT), 101 (p35S::H2B.2–YFP-9), 103 (p35S::H2B.8–eGFP-3, p35S::H2B.8ΔIDR–YFP-5), 104 (p35S::H2B.8–eGFP-5), 107 (p35S::H2B.8ΔIDR–YFP-2) or 109 (p35S::H2B.2–YFP-8) nuclei examined over two independent experiments.
