<p><b>a</b>) Days until first bud (green columns) and first flower (white columns) for WT, <i>pp2a-bα</i> (SALK_09504), <i>pp2a-bβ</i> (SALK_062614) in 12 h and 24 h days. <b>b</b>) Days until first bud (green columns) or first flower (white columns) for WT, <i>pp2a-bα</i> (SALK_032080), <i>pp2a-bβ</i> (GK_ 290G04) in 12 h and 24 h days. <b>c</b>) Numbers of leaves at first flower (dark green columns) and number of days to first flower (white columns) for WT, <i>pp2a-bα</i> (SALK_09504), <i>pp2a-bβ</i> (SALK_062614) in 8 h and 16 h days. <b>d</b>) Numbers of leaves at first flower (dark green columns) and number of days to first flower (white columns) for WT, and <i>pp2a-b’γ</i> (SALK_039172) in 8 h and 16 h days. The data show that the four <i>pp2a-b55</i> mutant lines tested were early flowering, and the <i>pp2a-b’γ</i> mutant line was late flowering under all conditions tested. For each genotype and treatment 30 plants were scored. SE is given. Columns marked with one or two stars are significantly different from WT at p < 0.05 and p < 0.01, respectively (student’s t-test).</p
