<i>NF-YC</i> mutants show opposing phenotypes in response to ABA.

<p>A–C) Germination of <i>nf-yc triple</i> mutants on B5 media, B5 media with 1 µM ABA, and in response to variable ABA dosage at 84 hours, respectively. D–F) As in A–C for all <i>nf-yc</i> double mutant combinations and G–I) single mutants. J) Percent germination for all <i>nf-yc</i> mutant combinations on 1 µM ABA at 84 hours. K) Percentage of plants with open green cotyledons at 10 days for all combinations of <i>nf-yc</i> mutants. L) Picture of 10 day old seedlings grown on 1 µM ABA; 1 = Col-0, 2 = <i>nf-yc3</i>, 3 = <i>nf-yc4</i>, 4 = <i>nf-yc9</i>, 5 = <i>nf-yc3/c4,</i> 6 = <i>nf-yc3/c9,</i> 7 = <i>nf-yc4/c9,</i> 8 = <i>nf-yc triple</i>. Asterisks for J–K represent Fisher’s Exact Test p-values; *p<0.01, **p<0.001, ***p<0.0001. Germination data is a compilation of two experiments (n = 6 replicates per genotype) using independent sets of matched seeds. Each replicate contained at least 30 seeds.
